That’s a hard question. It’s one I had to resolve, obviously, and hopefully I can give a few answers why.
The most pressing reason was my own weakness in failing to complete my catechumenate in the Orthodox Church. It was not as if I up and left Orthodoxy for Catholicism in one day. Almost a year passed between leaving the OCA parish for the last time and my first class in RCIA.
I hope to spend a few posts explaining why I entered that RCIA class rather than return to the Orthodox Church.
