I grew up a rather serious Lutheran, then branched out within Protestantism in college. John Piper, Francis Schaeffer, Tim Keller. Tons of Bible studies and podcasts. I found it to be rather intellectually satisfying.
This is all to say that I don't think bad theology was the issue here. My only issue was that I made too many friends who were missionaries (some with Wycliffe) and, inspired by how they were living life, I flew too close to the sun, as it were.
The "confessional" (theologically and vocationally serious) Lutheran church is having a big moment right now, and I think has a good framework for harnessing the strength and eagerness of young men, whether they should move away or take on parenting or local community-creating. But it's very small and asserts itself against the baby boomer gen x conservatism in the same churches, to a degree. Always some difficulty.
