This article analyses the parallels between the pre-Qin Daoist notion of heng 恒 as a constancy that is nevertheless ceaselessly in motion, and Karl Barth’s concept of Beständigkeit as God’s constancy throughout infinite transformation. Underlying both concepts is an understanding of the ultimate origin (whether dao 道or the Christian God) as irreducibly temporal in nature. Stemming from this conviction, both systems of thought ultimately identify the continuous change of the ultimate origin with the flow of time in the universe. The (...) commonalities found between these two traditions provide fresh resources to advance the study of both. On the one hand, Barth’s deliberate juxtaposition of contrary statements to illustrate the union of permanence and transience in Beständigkeit challenges the frequent assumption that similar juxtapositions in the pre-Qin texts comprise careless inconsistency or outright incoherence. By extension, Barth’s metaphysical underpinning of this juxtaposition offers a compelling framework to explicate the Daoist notion of heng. On the other hand, the pre-Qin texts’ confluence of permanence and freedom in the principle of ziran 自然 offers a new lens through which to read and hence redeem Barth’s oft-critiqued attempt to combine the irrevocability and ongoing freedom of God’s decision of election.
