Kant’s turn to the subject has changed the epistemological conditions for theology. Four intellectual backgrounds of objections are examined: an Aristotelian and Thomistic teleological order of nature (1); Augustinianism based on original sin in which human agency is completely attributed to God’s grace (2); a Hegelian critique of the deontological conception of an “unconditional ought” which also puts Kant’s postulate of the existence of God into question (3); the combination in Radical Orthodoxy of a postmodern critique of the subject, an (...) Augustinian view of human nature, and a monistic understanding of the Trinity (4). Their different diagnoses why Kant’s work constitutes a cul-de-sac are contrasted with theological positions that welcome it as a watershed: its move from ontology to human subjectivity; from a biologically transmitted inescapable sin to a freedom for good and evil; from a strict reciprocity to an unlimited scope of ethics that is faced with the question of meaning; and from condemning the secular as “heretical” to defining it as the genuine space of the free human counterparts created by God, according to Duns Scotus’s late medieval theology which anticipates Kant’s concept of autonomy. The standard by which theologies are judged is how they do justice to the New Testament’s message of salvation by Jesus Christ. The Conclusion argues that Kant’s turn to freedom in its unconditionality and finitude has opened up a thought form in which the truth of the Gospel finds more adequate categories of understanding than in those of earlier eras.
