Kant certainly was sympathetic with the metaphysical tradition of rational theology that he criticized.

Fichte thinks that the mutual recognition of one another as free beings belongs among the transcendental conditions of self-consciousness itself.

The moral law is simply the way we think our own freedom as self-determination.

Fichte is concerned with freedom as non-domination.

Reason necessarily expresses itself through emotions and emotions are healthy only insofar as they are expressions of reason.

Kant was a rational theologian. He did not pretend to be a biblical or revealed theologian.

In fact, if you read what Kant has to say about feeling, desire and emotion, you see that he is not at all hostile to these. He is suspicious of them insofar as they represent the corruption of social life (here he follows Rousseau), but he also thinks a variety of feelings (including respect and love of humanity) arise directly from reason - there is, in other words, no daylight between the heart and the head regarding such feelings.
