So Kant has this emphasis on moral duties. And if you have a God it's more likely that you're gonna obey your moral duties because you have some fear that God might punish you if you don't do them or reward you if you do them well. That's basically the basis for religion for Kant. That's it. So what does Kant say then about God's actual existence? That's the numina. That's the thing in itself. That's the realm that I don't access. So who knows? Who knows? That's really where Kant comes. And so there are a number of thinkers that are influenced by Kant. There are Kantians and then neo-Kontians. But there's a particular Lutheran figure who's really important in this story and that is Albert Richl. Now if you're gonna discuss what is Protestant liberalism in the 19th century, which I mean technically I guess 1799 is the beginning. So just prior to the 19th century. But Protestant liberalism was basically a movement largely among German Protestants and I've expanded beyond that to say we can still be Protestant Christians but also be good rationalists at the same time. We can make a kind of more rational form of Christianity that denies the supernatural. And Kant gives impetus to some of these ideas in Christian liberalism, particularly that of Albert Richl. And Richl, he is a student of a guy named Herman Lótze who's a neo-Kontian. So he's kind of a next generation later guy who's drawing on Kant. And Richl essentially buys into the major points of Kant's system. He essentially says, he's a theologian here, not a philosopher. So Richl has a theologian says yeah the church is great, the Lutheran church in particular he's saying is necessary for society. Why is it necessary? Because it creates a moral community. Moral community is really the purpose of the church. And we don't really have access to the truths like all that abstract stuff about the Trinity or the pre-existence of Jesus. Like all that. That's all numina. That's all stuff that we don't really have any access to. So he's going to focus on what we can understand, what we can experience, particularly in terms of morality for Richl. Others like Schleiermacher does this in terms of religious feeling and sentiment. So how does this relate to the Doctrine of Union with Christ? Well, Richl has a very influential study of Martin Luther's theology. That's known as Richard's Luther's study. And he devotes a significant amount of time reading and reevaluating Luther's writings. And he does this in a few different works.
