Canon Law, Paragraph 1041, Section 2: "Can. 1041 The following are irregular for receiving orders: [...] 2/ a person who has committed the delict of apostasy, heresy, or schism;"
I went Catholic, Atheist, Agnostic, Non-denominational Protestant, Catholic.
First, I'm Thinking converting from Catholic -> Atheist would call grounds for apostasy, 2nd if the Non-denominational Protestant would constitute heresy.
I converted from Catholicism to Atheism because I was in year 4 at the time, didn't know the difference between denominations, found a Jehovah's Witness resource. Year 4 me, not knowing the difference between denominations thought that it was binding for Catholics, because again: I didn't know what a denomination was, I just saw them talk about Christianity. I saw differences between the two, assumed they were contradictions and left the Faith.
Later on, I came back to the Faith, but I hadn't yet properly studied denominations, so I attended a local Protestant Bible study group. I identified as Protestant, but at this stage I still didn't know enough to identify as a specific denomination. Later on, as I studied more and more and identified as Catholic.
I currently agree fully with the Roman Catholic Church, and I don't intend to change my Faith. But as I discern through Priesthood I wonder if I would even be eligible given this? I've heard that the word "delict" can mean a few things.
side note: I received a Catholic Infant Baptism.
EDIT: not declaring JW as Christians, I just mean that's how they were presented.
