本文對巴特發表於1936年的《上帝恩典揀選》進行細讀分析，探討他如何將神學本體論與認識論的核心從歷史時間的實動性轉移至耶穌基督全然永恆又全然屬歷史的實動性。筆者將專注討論巴特如何使用德意志觀念論的術語來建構當前英語學界所謂的「實動本體論」，以修正拉丁神學傳統之先賢的形上學預定論。本文的立論是，巴特於1936所發展的基督中心揀選論，乃對上帝不可棄存揚升之主體性在上述實動本體論框架下的反思。這套本體論對揀選教義的表述，可在以下關鍵辯證的基礎上理解之：十字架是揀選的外在基礎，而揀選是十字架的內在基礎。

This article comprises an exposition of Karl Barth's Gottes Gnadenwahl (1936). The treatise represents a significant statement of the Swiss theologian's relocation of the centre of theological ontology and epistemology from a locus in temporal actuality to a locus in the actuality of Jesus Christ who is at once eternal and temporal. In this article I will unpack some important implications of this turn to Christocentrism by a close reading of the text, paying close attention to Barth's critical employment of German idealist vocabularies in his development of what might in a qualified sense be called an “actualistic ontology” as a corrective to the metaphysical doctrines formulated by his Latin predecessors. I will set forth the thesis that the Christocentric doctrine of election Barth developed in 1936 is a reflective after-thinking (Nachdenken) of God's unsublatable subjectivity in the framework of the actualistic dialectic: Golgotha is the outward basis of election, and election is the inward basis of the crucifixion.
