There is a weekly FSSP service here in my city and it’s beautiful. I would seriously look into this if I were you. If I had it to do all over again starting as a young teenager and knowing what I know now, I would have prepared myself academically, spiritually, morally, and with discipline to become a priest with them, or at the very least seriously discern a vocation with them. Unfortunately, none of that happened.
When I was going through RCIA when I was 35 I just knew I had missed my calling. I have ended up being a “helping voice” at two separate RCIA classes in the years that followed. People say I have a way of teaching the faith well. I knew as soon as I saw my first mass that the priest had the vocation (although I didn’t know to call it that then) that I was called into, but I had screwed up and it was too late. Young man I urge you if you feel you MIGHT be called to the priesthood to discern it somewhere, whether in a religious order or at your local seminary for your diocese. You just don’t know the heartache of a missed vocation, and there really does come a time when it’s too late. At the chance of offense to the SSPX folks I am going to say this: Young man if you start playing around with separated groups, it may well be too late for you sooner than you think.
I am going to say an additional rosary just for you tonight young man. Pray for me too OK? I have a new full time job and am trying to go to school full time to be a medical coder. It will take 18 months. After I get out of school and get a new job, I want to go to Guadalupe Bible College to maybe prepare myself to take up a serious apostolate teaching scripture.
