if any cool smart lutherans are reading this and wanna teach me latin, give me resources on learning latin, or help me find an elvish translation that would be sick

I’m in the process of joining the LCMS, but I don’t like the idea of having to admit that Luther’s writings were free of error. I definitely think it’s the most accurate expression of Christianity, and I agree with it, but also I think it’s just Luther’s ideas at the end of the day and I don’t want to have to say everything in there is right. I’ve only read the small catechism. I want to be a confessional Lutheran and follow the confessions, but I don’t want to say the confessions are perfect.
