What was the hardest part of leaving Protestantism?

My biggest obstacle was the fact that I spent a lot of time studying theology and Protestantism. I was a religion and philosophy major. I had spent a number of years studying apologetics under Greg Koukl with Stand to Reason. I had been to L'Abri Fellowship, which was created by Francis Schaeffer. I had all these Protestant questions and ideas, and my biggest stumbling block was I couldn't find corresponding Orthodox answers. So what I realized was, Protestantism was a theological framework that was a response to Roman Catholicism. And so the dialogue between Catholic and Protestant was like question to question, question to question, question to question. It was very harmonious. And I started to realize that Protestantism and Catholicism were two sides of the same coin. They were the same theological coin, asking the same theological questions but with different answers. The thing that was a big hang-up for me when I came to Orthodoxy, I was like, well, what are the Orthodox answers to my Protestant questions? I just had to educate myself and come to the realization that the church fathers were not former Protestants. They did not believe in Protestantism. They did not have a Catholic framework. They were Orthodox. And the way that they saw life, the healing of the soul, deification, the acquisition of the grace of the Holy Spirit, all of these things had everything to do with the fact that they were not Protestant or Roman Catholic. And so my great struggle was trying to find answers to these questions that I had that made sense. And the reality was, I realized Orthodoxy was very foreign, but it was very foreign because of the fact that I was trying to answer Protestant questions. And I just realized I had to get rid of the questions and I had to find new questions, which were the questions of the church fathers, and I had to listen to their answers. And I think that kind of theological autonomy that I was under, where I could have my own version of Christianity, was very powerful. I had all my own answers, all my own thoughts, all my own conclusions, and I realized that I needed to repent from that and come into the church and listen to what the saints had to say.
