In this review article, the book by J.H. van Wyk, Augustine: A study on the ethics of the church father from Africa is presented and discussed. Short overviews of the content of the six chapters are given. They are: Introduction – the necessity for a book on Augustine’s ethics in Afrikaans, Orientation – an overview of his life and works, Grounding – the relationship between dogmatics and ethics, Typology – the character of his ethics, Themes – marriage and sexual ethics, (...) political ethics and animal ethics, Findings – evaluation of Augustine’s ethics. Support is given to the argument that Augustine is an important forerunner to the Reformation. Information is provided on Augustine and the early years of the Reformation in Wittenberg. Critical remarks are made about the author’s understanding of the relationship between faith and works, dogmatics and ethics. The Lutheran understanding of this topic is presented as an important alternative to the Reformed version that is defended in this book. Finally, attention is given to Augustine’s ‘theory of the two cities’. Also in this regard advice is given from one of Luther’s publication. His exposition of Mary’s Song in Luke 1:46–55 is used as an example of how a witness to the government could look like. (shrink)

Schonsheck attacks views which seek to justify the majority of citizens of a society passing legislation that is designed to serve the purpose of preventing their own first order preferences from changing over time . The issue that I think is more important is a related one, but not precisely the same. It is not whether it is morally permissible for the majority of members of a society to pass legislation designed to prevent their own individual preferences from changing over (...) time, but whether it is morally permissible for them to pass legislation for the sake of preventing the community's preferences from changing over time. As some people mature and acquire preferences and others die, no individual's already-formed preferences have to change for the community's preferences to change. The arguments concerning these two issues are the same, or at least similar, but putting the matter the way I do, raises the question of influencing the preferences of children. I argue that there is nothing intrinsically wrong with a community's doing this and that Schonsheck's arguments to the contrary either are not convincing, or apply in some cases but not in others.

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.

This article gives a short reflection on the background and origin of the social-scientific model change agent in relation to change agency, a relationship that causes an alternate state of consciousness for the change agent. Arguing from the seven-point explanation of Malina and Pilch of how a change agent operates, this article applies the model to the letter to the Ephesians. The conclusion is that this social-scientific model is helpful for the recent church to realise how narrow the relation is (...) between Jesus Christ and the church, in view of the future of the church as a future in Christ. A choice is made to find alternate words in the Afrikaans language suitable for the theological debate, namely opdraggewer [change agency], meningsvormer [change agent] and alternatiewe staat van bewussyn [alternate state of consciousness].

The grammar of faith language in the Canons of Dordt as a result of the nation-state ideology. This article aims to decipher the spirit of the notion ‘predestination’ codified in the Canons of Dordt. It reconsiders the relevance of these dogmatic propositions about predestination as a grammar of the faith language which originated in a very specific context, namely the political concerns and the religious convictions held in the uniting Dutch provinces as a nation-state. In this context Calvin’s views about (...) predestination became instrumental to the establishment of an upcoming nationalistic ideology, based on different interpretations and perceptions of Calvin’s theology. Within the context of the Protestant Dutch resistance against the RomanCatholic Spanish-Habsburg hegemony, the Canons were formulated during the Synod of Dordrecht in 1618–1619 as a Calvinistic movement against the Remonstrants who were stigmatised as collaborators of the Spanish-Habsburg reign over the Netherlands. This article demonstrates that different receptions of Dordt heighten the dogmatic gap between the socalled liberal modernism of the Remonstrants and a strict confessionalism of neo-Calvinism which has influenced the present-day understanding of the Canons of Dordt. It is argued that the grammar of the Canons of Dordt needs to be understood against this background and the meaning of the faith language it reflects, interpreted accordingly. (shrink)

In hierdie hoofstuk word Jürgen Moltmann se bydrae tot Reformatoriese teologie ondersoek. Sy teologie kan beskryf word as 'n teologie wat Bybels gegrond is, 'n eskatologiese gerigtheid en 'n politieke verantwoordelikheid het. Dit is juis om hierdie rede dat sy teologie ook 'reformatories' is. Dit is 'n beskrywing waarvoor hy ook doelbewus kies, omdat die begrip 'reformatories' die dinamiese, voortgaande en profetiese karakter van Reformatoriese teologie aandui. Hierdie teologiese karakter kom veral na vore in Moltmann se verstaan van die Triniteitsleer (...) en sy trinitariese teologie, wat beskryf kan word as 'n 'Trinitariese teologie van solidariteit en sosiale geregtigheid.' Die lewensruimte van die Triniteit word deur Moltmann as 'wye ruimte' beskryf, en as 'n 'uitnodigende ruimte' waarin daar nie beknoptheid is nie. Binne die hoofstuk word dit geargumenteer dat Moltmann se Triniteitsteologie die hartklop is van sy bydrae tot Reformatoriese teologie. Dit is baie nou verbind aan sy politieke teologie en word geïllustreer op die wyse waarop sy Triniteitsteologie en sy politieke teologie van inklusiwiteit en geregtigheid met mekaar verweef is.

The sentence 'to rule with him in the heavenly world' as example of an eschatological highlight in the letter to the Ephesians: The viewpoint in this article is that the above-mentioned statement in the letter to the Ephesians can be seen as an eschatological sentence of extraordinary value. In view of different eschatological viewpoints from the past, it can be stated that this sentence is an example of eschatology not only for the future, but also for the present. It is (...) understandable that there is a close link between eschatology and mission. The meaning of theosis, a concept from the Eastern churches' theological debate, underlines the need for a present eschatological consciousness that has significance for the future of church and faith. Believers can in this way escape from the destructive lust that is in the world, and may become partakers of the divine nature. (shrink)

Metaphors for the encounter between God and humanity and a roaming theologian’s reflective journey. This article maps the theology of Christo van der Merwe as a mobilising theology which aided the Netherdutch Reformed Church in Africa in discerning its character, role and purpose. The core of Van der Merwe’s theology consists of a journey with God as encountered in the narratives about Jesus and the Spirit told in the Christian Bible. The article shows that the mobilising core of his theology (...) is due to an ‘interoperational relationship’ between ‘knowing and believing’. In the article, the metaphor ‘roaming’ is used to illustrate this biographical journey as contextual theology which equips pastors with ministerial skills to take care of people who are haunted by trauma.

Universities introduce intermediate assessment because it is understood to have positive effects on student behaviour and achievement. Yet, how intermediate assessment is perceived might be conditional for its success. The current study investigates both teachers’ and students’ perceptions of intermediate assessment. Teachers and students were interviewed and Student Evaluations of Teaching were examined. Results indicate that both teachers and students had generally positive perceptions of intermediate assessment. However, the two groups provided different reasons for their positive perceptions. Teachers and students (...) agreed that intermediate assessment helps students to keep up with their study work. Moreover, teachers mentioned that they could assess various knowledge and skills with intermediate assessment, whereas students preferred intermediate assessments to test the same knowledge and skills as the final exam. This finding suggests that teachers and students in our study had different goals... (shrink)

This article discusses the meaning of ecclesiology and church polity as such, in relation to each other, but also in connection to church order which lies in the elongation of both. From a reformed perspective, it is indicated that the ecclesiology of the Netherdutch Reformed Church over the last fifty to hundred years, centred round the viewpoint of the Church as a volkskerk, in conjunction with the church orderly, of the Kerkwet till 1997. The author is of the opinion that (...) the above-mentioned viewpoint limited the church to be a true church of the Word. (shrink)

The relationship between Colossians and Ephesians as a synoptic problem. Research by different scholars concluded that some letters traditionally ascribed to Paul were probably not written by him and drew a distinction between Pauline and Deutero-Pauline letters. The majority of scholars nowadays are of the opinion that the letters to the Colossians and the Ephesians are Deutero-Pauline and that Ephesians, at least, was surely not written by Paul. The results of research on the synoptic problem can be used and applied (...) to the two letters under discussion because a comparison shows that there are striking similarities between the two. The most recent research shows that Ephesians made use of the letter to the Colossians but not without redactional changes to suit the author’s literary purpose. This method is exegetically known as redaction-criticism, linked to the social-science viewpoint that the author of the letter to the Ephesians acted as a change agent on behalf of a change agency.

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)

Vryheid is naas regverdiging een van die belangrikste temas van die Reformatoriese teologie. Luther se geskrif 'Oor die vryheid van 'n Christenmens' is een van sy hoofgeskrifte. In hierdie geskrif beskryf hy die vryheid van die innerlike en die uiterlike mens. Die innerlike mens is vry en niemand se onderdaan nie. Die uiterlike mens is weer elke ander mens se onderdaan en dienskneg. Die Christen dien sy medemens deur die liefde. Luther se verstaan van naasteliefde word vanuit ander geskrifte toegelig. (...) Johannes Calvyn se verstaan van vryheid volgens sy 'Institusie' van 1559 word ook bespreek. Daar word op die groot ooreenstemming tussen Luther en Calvyn gewys. Die verskille tussen die twee Reformatore is minimaal. Calvyn het egter wel groter aandag aan die adiafora-vraagstuk gegee. Daar word ook deurgaans na Philipp Melanchthon se invloed op Calvyn gewys. Die relevansie van die vryheidsvraagstuk lê nie in die instrumentalisering van die Christelike vryheid nie, maar in die hernude bestudering van die klassieke tekste met die bedoeling om die belangrike reformatoriese motiewe te herontdek. Hierdie motiewe is relevant - ook in ons samelewing. (shrink)

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.
