I had been inquiring into Orthodoxy for about 14-16 months when I became a catechumen in the Antiochian jurisdiction. There was no ceremony or anything, the priest just said that I was now a catechumen, we went into his office, looked at the calendar, and he decided that I'd be received roughly 6 months later (Dec. 22, 2001). He assigned someone to catechise me, and this person was also my godfather. My catechist would answer any questions that I had, and we got together a few times to discuss various things. I was reading a lot on my own (too much reading, and not enough praying, to be honest), so that wasn't really a concern. I don't recall all of what I read during that time, but three I do remember were The Cappadocians by Anthony Meredith, The Arena by St. Ignatius, and Orthodox Faith and Life in Christ by St. Justin. The chrismation date came, I got received, and that was that.
