Just some background before I ask my questions:
I was raised an Orthodox Jew, and discovered traditional Catholicism via my Italian grandmother (my mother was a convert to Orthodox Judaism circa 1944). I’ve been a traditional Catholic ever since the age of 18.
After my conversion (which I studied for with a very traditional priest at my local parish, this was 1978), I became deeply emmeshed in Church history, apologetics, hermeneutics, moral theology, and canon law. I began debating protestants, and after a lapse of some years to raise my family, I’ve returned, this time online.
Maybe because I was never a protestant I don’t understand this, but WHY are they so close-minded and harbor such irrational and frankly ridiculous hatred for the true Church? Were they raised that way? The ex Catholics can be just as bad if not worse, and I find often turned against the Church for marriage reasons (divorced, wanted to remarry, Church wouldn’t let them, so they went to a protestant sect that would let them).
One question my son asked me, and I had to admit I did not know the answer: a heretic is a baptized Catholic who has chosen to deny certain central dogmas of the Faith (Luther having been a good example).
But what is someone who was raised in a protestant group, never baptized Catholic, and simply believes as they do because they don’t know any better? What category do they fall into? Heretic? Schismatic?
I remember learning that there are Infidels, Apostates, Schismatics, and Heretics: Infidels are the unbaptized; Apostates are baptized Catholics who ahve entirely given up the Faith; Schismatics are those who deny the Papacy, and Heretics are those who still claim to be Christian (Catholic), yet who0 deny certain key articles of the Faith.
