Gerhard Ebeling on faith. Gerhard Ebeling (1912–2001), not only the foremost Luther researcher of the previous century but also one of the most prominent contributors to protestant theology during that period, wrote extensively about faith throughout his long and productive life as a professional theologian. He learnt from Luther that discerning judgement in the differentiation of related matters forms the basis of all sound theology. Applying this insight to his own thought, he reflects on the development of the phenomenon of (...) faith in the Old Testament community and early Christianity and the formalisation of the concept for use in the domain of religious studies. He defends the argument that Christian faith is not only faith in Jesus as the Christ and Lord but also that Jesus, and He only, is the founder and perfecter of faith. The concept of faith is also explored by Ebeling in relation to love, life and reason. The article concludes with a critical evaluation of Ebeling’s contribution in guiding us to witness authentically about our own faith in Jesus Christ within our own situation and against the background of the problems it poses for believing in Christ.

Die voortgesette proses van implementering van nuwe materiaal wat gebruik word vir katkisasie in die Nederduitsch Hervormde Kerk van Afrika vertoon 'n besondere trajek. Die proses het, in terme van geloof, begin met die formalisering van sowel die geloofsbegrip as die beskrywing van die inhoud van geloof. Dit is voortgesit deur 'n proses van die objektivering van die inhoud van geloof tot feite wat geleer kan word en is uiteindelik voltrek deur die implementering van 'n pragmatiese opvoedkundige doelwit waarin geloof (...) bloot 'n middel tot 'n doel geword het. Die trajek kan kortliks soos volg beskryf word: • Die Heidelbergse Kategismus Geloof is die aanneming van die beloftes van God wat vertroue in die lewende God skep. • 'Kortbegrip': Geloof is sekere kennis van God en sy beloftes en 'n hartlike vertroue dat al my sondes om Christus ontwil vergewe is. • Die belydenis van die Hervormers: Ek glo in God beteken dat ek al my vertroue op God stel en Hom op sy woord neem. • Geloofsleer: Geloof is kennis van die Woord van God en vertroue in die God van die Woord. • Geloof en Lewe 11: Geloof is die toe-eiening van kenbare geloofoorleweringe wat in die Bybel opgeneem is. Die kerk kan daarom kinders deur 'n proses van kategese begelei tot geloofsvolwassenheid. Vandag is die uitgangspunt van katkisasie en die motivering daarvoor in die Nederduitsch Hervormde Kerk van Afrika die oortuiging dat die kerk kinders deur 'n proses van kategese tot godsdienstige volwassenheid kan lei. Van Selms se kategismus pas nie in die trajek wat hier beskryf word nie. Die Nederduitsch Hervormde Kerk van Afrika sou vandag heeltemal anders gelyk het as meer as een generasie van die lidmate van die Kerk aan hierdie kategeseboek blootgestel was. (shrink)

Rudolf Bultmann was one of the leading thinkers within an influential theological direction that arose in Europe after the First World War, known as dialectical theology. Comprehensive introductions to the life and work of Bultmann in the South African theological journals, written in Afrikaans, either does not exist, or are difficult to trace for the Afrikaans readership. This article on Bultmann aims to fill the gap by offering a lexicographical contribution on the life and work of Bultmann. The focus of (...) this article is on Bultmann as a Lutheran thinker. The theme of the New Testament and systematic theology is essentially the same, namely to explain the concept of Christian self-understanding as an eschatological event in which faith is expressed for the sake of faith in God and only in God. Bultmann explained the same theological concepts with his theology as those that were explained by the church reformers of the 16th century, but under radically new circumstances. The so-called modern and postmodern people of our time not only broke ties with the past, but in the process they also lost their ability for using historical-critical patterns of thought that tries to bridge historical distances, and therefore sacrificed all efforts to think systematically on the altar of relativism. We can learn from Bultmann what systematic reformed theology really is. (shrink)

Disputations were a fixture of Martin Luther’s academic career. Luther participated regularly in disputations. It was an important communicative vehicle through which he developed and expressed his theology. The well-known 95 theses are a case in point. Luther’s career as a disputator was impressive. Several of his most influential disputations were explicitly intended for consideration by his academic and ecclesiastical colleagues, but the majority of his disputations took place as a curricular exercise at the University of Wittenberg. The purpose of (...) these disputations was pedagogical and polemical. Luther deployed the same tools for his defence of proper doctrine that were at the centre of the Protestant reformation in the face of objections. The disputatio de homine is a systematic summary of Luther’s anthropology. It incorporates the doctrine of justification as the theological definition of man. It treats the subject within the context of the relationship between theology and philosophy, and reflects upon the new language of theology. The disputatio de homine provides an essential resource for the study of Luther’s anthropology and the doctrine of justification. (shrink)

The gospel is not a new law. A clear distinction must be made between law and gospel, so that the gospel is not mistakenly understood as a new law, but as the gospel. The relationship between law and gospel must be considered carefully. Two prominent theologians, Martin Luther and Karl Barth, did just that, but in opposition to one another. This article describes and compares their respective views. Barth defends a political use of the gospel. The gospel provides believers with (...) action instructions for the civilian life. Barth argues in terms of analogical thinking and, according to him, believers’ understanding of reality is determined by their understanding of Christ. Luther, on the other hand, believes that the preaching of Christ and the life experience are in contrast. Faith and life are not identical. He understands the believer as the hearer of the gospel – as passive recipient of the grace of God. The passivity here, however, is a highly creative one. The relevance for us of the theological position defended regarding law and gospel is evident from the document ‘Association of the World Communion of Reformed Churches with the Joint Declaration on the Doctrine of Justification’. The spirit of the document is clearly Barthian. Fundamental theological differences are on the table with the Lutheran position and there is no question of real consensus. Intensive study and frank ecumenical conversation is required to seek real consensus for the sake of a clear Christian testimony in the world. (shrink)

Cell line immortalisation is a growing component of African genomics research and biobanking. However, little is known about the factors influencing consent to cell line creation and immortalisation in African research settings. We contribute to addressing this gap by exploring three questions in a sample of Xhosa participants recruited for a South African psychiatric genomics study: First, what proportion of participants consented to cell line storage? Second, what were predictors of this consent? Third, what questions were raised by participants during (...) this consent process? 760 Xhose people with schizophrenia and 760 controls were matched to sex, age, level of education and recruitment region. We used descriptive statistics to determine the proportion of participants who consented to cell line creation and immortalization. Logistic regression methods were used to examine the predictors of consent. Reflections from study recruiters were elicited and discussed to identify key questions raised by participants about consent. Approximately 40% of participants consented to cell line storage. The recruiter who sought consent was a strong predictor of participant’s consent. Participants recruited from the South African Eastern Cape, and older participants, were more likely to consent; both these groups were more likely to hold traditional Xhosa values. Neither illness nor education were significant predictors of consent. Key questions raised by participants included two broad themes: clarification of what cell immortalisation means, and issues around individual and community benefit. These findings provide guidance on the proportion of participants likely to consent to cell line immortalisation in genomics research in Africa, and reinforce the important and influential role that study recruiters play during seeking of this consent. Our results reinforce the cultural and contextual factors underpinning consent choices, particularly around sharing and reciprocity. Finally, these results provide support for the growing literature challenging the stigmatizing perception that people with severe mental illness are overly vulnerable as a target group for heath research and specifically genomics studies.

International political, social, economic and religious developments influence how local communities operate. The South African church society is influenced by such developments taking place globally and which clearly influence how local churches function. This article explores the role of the contemporary church as a ‘reformation agency’ in enhancing a socially transformative agenda in South Africa. A qualitative research approach – an interpretative phenomenology design – was employed to negotiate a shared understanding through conversation and intersubjective meaning-making with church ministers, with (...) the primary focus being their subjective experience of the changing role of the church in enhancing a transformative agenda in a South African context. A purposive sampling consisted of local church leaders who participated in the face-to-face and telephonic semi-structured interviews to achieve the purpose of the study. The findings clearly show that deliberate and intentional actions by churches allow them to become a voice for the marginalised, to create spaces for searching for excellence and to increase the quality of servant leadership, all as vehicles for transforming church society. Furthermore, servant leadership is a social phenomenon, a philosophy-in-practice aimed at leading by example to achieve a common goal. To accomplish this, church ministers are required to spearhead the challenge as a prerequisite to creating ‘lived experienced’ opportunities for members as an inward-outward spiritual journey. Finally, church leaders believed that transformation is a secular dimension, but that it can also be aligned towards God’s redemption plan and enhancing a socially just transformation agenda. Ultimately, this study proposed several recommendations to allow the local church to be relevant in practicing and promoting stronger unity and reconciliation amongst all churches nationally and globally.

In this paper we present an executable approach to model interactions between agents that involve sensitive, privacy-related information. The approach is formal and based on deontic, epistemic and action logic. It is conceptually related to the Belief-Desire-Intention model of Bratman. Our approach uses the concept of sphere as developed by Waltzer to capture the notion that information is provided mostly with restrictions regarding its application. We use software agent technology to create an executable approach. Our agents hold beliefs about the (...) world, have goals and commitment to the goals. They have the capacity to reason about different courses of action, and communicate with one another. The main new ingredient of our approach is the idea to model information itself as an intentional agent whose main goal it is to preserve the integrity of the information and regulate its dissemination. We demonstrate our approach by applying it to an important process in the insurance industry: applying for a life insurance. In this paper we will: (1) describe the challenge organizational complexity poses in moral reasoning about informational relationships; (2) propose an executable approach, using software agents with reasoning capacities grounded in modal logic, in which moral constraints on informational relatio nships can be modeled and investigated; (3) describe the details of our approach, in which information itself is modeled as an intentional agent in its own right; (4) test and validate it by applying it to a concrete ‘hard case’ from the insurance industry; and (5) conclude that our approach upholds and offers potential for both research and practical application.

This study examines the extent to which the highly diverse and volatile Dutch electorate received a diverse offer of political newspaper coverage during the 2006 general election campaign. We measured the level of diversity of five subscription based national newspapers with a partisan history and two free dailies. Two forms of diversity were examined: party diversity and issue diversity. The diversity of party coverage in the free dailies was greater than the diversity across all newspapers. Whereas free dailies paid a (...) relatively large amount of attention to new and opposition parties, traditional newspapers paid a relatively large amount of attention to the parties with whom they were aligned during the period of “pillarization”. Conversely, we only found small differences in the distribution of attention to issues. The diversity of issue coverage across newspapers was larger than the diversity within newspapers. (shrink)

Individuals make decisions under uncertainty every day. Decisions are based on in- complete information concerning the potential outcome or the predicted likelihood with which events occur. In addition, individuals’ choices often deviate from the rational or mathematically objective solution. Accordingly, the dynamics of human decision making are difficult to capture using conventional, linear mathematical models. Here, we present data from a 2-choice task with variable risk between sure loss and risky loss to illustrate how a simple nonlinear dynamical system can (...) be employed to capture the dynamics of human decision making under uncertainty (i.e., multistability, bifurcations). We test the feasibility of this model quantitatively and demonstrate how the model can account for up to 86% of the observed choice behavior. The implications of using dynamical models for explaining the nonlin- ear complexities of human decision making are discussed as well as the degree to which the theory of nonlinear dynamical systems might offer an alternative framework for understanding human decision making processes.

As part of the Dutch national science program “Professional Games for Professional Skills” we developed a stress-exposure biofeedback training in virtual reality for the Dutch police. We aim to reduce the acute negative impact of stress on performance, as well as long-term consequences for mental health by facilitating physiological stress regulation during a demanding decision task. Conventional biofeedback applications mainly train physiological regulation at rest. This might limit the transfer of the regulation skills to stressful situations. In contrast, we provide (...) the user with the opportunity to practice breathing regulation while they carry out a complex task in VR. This setting poses challenges from a technical – as well as from a user-experience perspective. We illustrate how we approach these challenges in our training and hope to contribute a useful reference for researchers and developers in academia or industry who are interested in using biosignals to control elements in a dynamic virtual environment.

A tolerant treatment of church order and the law of usance: This article discusses the recent decline of church polity in the Netherdutch Reformed Church which is obvious in different areas of the Church with special reference to the liturgy practised in sermons of some congregations. This decline is also observed in other churches in South Africa and abroad. The article is a reaction to the reason for this situation and indicates that it should not be found in a collegialistic (...) concept of church, but rather due to congregationalism or independentism in modern form. The article’s viewpoint is that the above-mentioned church polity decline is a result of the fact that church order is not valued as an order with a Scriptural and therefore an ecclesiological basis.

Ephesians 1:14 and 1:22, 23 as a scriptural maximum-minimum for ecclesiology. Against the background of a membership decline in mainstream churches in South Africa and abroad, and conscious of the theological debate in which a missional ecclesiology is presented as at least part of the modern-day solution to the problem, this article points in the direction of a Christological ecclesiology as an important ecclesiological point of departure. The article gives an exegetical outline of Ephesians 1:14 and 1:22, 23 as a (...) critical maximum-minimum for a Christological ecclesiology and as a means of making missional ecclesiology more acceptable.

It is widely recognized that police performance may be hindered by psychophysiological state changes during acute stress. To address the need for awareness and control of these physiological changes, police academies in many countries have implemented Heart-Rate Variability biofeedback training. Despite these trainings now being widely delivered in classroom setups, they typically lack the arousing action context needed for successful transfer to the operational field, where officers must apply learned skills, particularly when stress levels rise. The study presented here aimed (...) to address this gap by training physiological control skills in an arousing decision-making context. We developed a Virtual-Reality breathing-based biofeedback training in which police officers perform deep and slow diaphragmatic breathing in an engaging game-like action context. This VR game consisted of a selective shoot/don’t shoot game designed to assess response inhibition, an impaired capacity in high arousal situations. Biofeedback was provided based on adherence to a slow breathing pace: the slower and deeper the breathing, the less constrained peripheral vision became, facilitating accurate responses to the in-game demands. A total of nine male police trainers completed 10 sessions over a 4-week period as part of a single-case experimental ABAB study-design. Results showed that eight out of nine participants showed improved breathing control in action, with a positive effect on breathing-induced low frequency HRV, while also improving their in-game behavioral performance. Critically, the breathing-based skill learning transferred to subsequent sessions in which biofeedback was not presented. Importantly, all participants remained highly engaged throughout the training. Altogether, our study showed that our VR environment can be used to train breathing regulation in an arousing and active decision-making context. (shrink)
