Most of my higher education was reformed Presbyterian at RTS. I remember taking Dr. James Andersons class dealing with doctrinal definitions, counters, proof texts, and rebuttals for the doctrines of grace and being blown away at the reformed systematic theology and its universal application. So most of my Christian life I was reformed, and that is still how my brain is wired, though I have worked as a volunteer children's minister in a charismatic church for the last decade 😅.
Orthodoxy hit me like a semi about a year or 2 ago, and my worldview was destroyed for the most part. While I naturally default to reformed thought, there is that nagging voice in the back of my head telling me I'm probably 99% wrong on most of it. That being said, having a broken systematic theology has forced me to trust less on my intellectual ability to determine truth from heresy through my own subjective interpretation abilities, and has forced me to be more prayerful and dependent on Him. I see it as a win lol
