Two Christians Take On Postliberalism: The increasingly hostile political landscape requires a reevaluation of the roles of church and state. (Hunter Baker, March 8, 2024, Modern Age)
As a matter of conviction, Baptists would tend to reject Christian nationalism because of their strong emphasis on a regenerate church community. That means that they envision a church whose members have voluntarily and enthusiastically embraced the Christian faith. It also means Baptists have tended to be great advocates of religious liberty, as they deem forced religion to be an offense to God through its production of hypocrisy. It is no surprise, then, that Miller opposes Christian nationalism.
Wolfe, as a Presbyterian, comes from a denominational background that is connected to the Magisterial Reformation, which was certainly comfortable with national churches. It is probably no accident that the Baptists vigorously reject infant baptism, while both Presbyterians and Catholics embrace it. One cannot fail to notice that in the national churches of the types Magisterial Reformation traditions and the Catholic Church employed, to be born effectively meant to simultaneously enter the church as a Christian and the state as a citizen. This style of Christianity is comprehensive (in that it comprehends almost all citizens within its community) as opposed to the regenerate style that has appeared to work well in modernity. Wolfe would like to return to the comprehensive Christianity of the old national churches and their partner states.
