don't attend any sort of seminary. Weirdly, many fundamentalists just don't look into the history of their faith that much.
I grew up Lutheran, which is a very nerdy and self-examining denomination, and many Missouri Synod Lutherans do believe that the Bible is the inerrant and inspired Word of God. I learned in my parochial high school about the Council of Nicea, from an ordained Lutheran pastor. Lutherans generally do not believe the evangelical nonsense that Catholics aren't "true" Christians, though. They think Catholics are wrong, of course, and that only (their specific flavor of) Lutheranism is truly right, but that generally anyone who believes Jesus died for their salvation "has it right enough for the endgame", as it were.
Basically what I was taught as a religious youngster was that the Catholics were the closest to "right" out of all historical versions of Christianity (Arianism, Gnosticism, Adoptionism, and later, Orthodox)...until, of course, Luther came along to fully set things right. Why did that take close to 1600 years? Well, that's not a question you want to ask in a parochial high school class taught by a pastor.
