 Moreover, Kant sees faith, unlike knowledge, as engaging with our will, calling it a “free assent”. This is important for the practical function of faith, since our commitment to morality does not so simply depend on our affirmation of the postulates, but in our free act of faith through which we more completely bind ourselves to morality. Morality, thus “inevitably leads to religion” (AK 6:6 [1793]), since we need the latter in order to sustain or fully realize our commitment to the former. This, however, must not be interpreted as “theological ethics”, as if the authority of the moral law depended upon God. It is not its authority that is in question (perhaps with the exception of the argument at AK 5:114 in the Critique of Practical Reason [1788]). Rather, this advance from morality to religion concerns how we bind ourselves to the former (cf. A632/B660, AK 5:481 [1788], AK 6:3 [1793]).
