Read Paul’s letters to the Churches. Read James and John, that’s how you will know that the church is basically the same. Again, I never said that there was no interruption in the doctrine, when the RCC has a monopoly they’re loath to give it up, but Luther put an end to that, along with faithful Baptist churches in Germany.
And yes, my degrees are in Political Science and History, double major.
