I found in writings that he was told that after death he would be an apostle.
If you aren't willing do a simple search online to verify the existance or non-existance of a saint Its hard to have an honest conversation.
And as to your complaints of the players listed to help those who read they were all bracketed to inidicate they were amended to the text.
Shameless would have been that the editor made alterations and wrote them in unbracketed leaving the reader to think that they were the text.
I believe the Orthodox Church has Constantine as a saint and also has sometimes referred to him as the '13th apostle' - I dunno, you'd have to ask an Orthodox about that.
What Catholic sites did you find that in? A brief googling of "St. Constantine" yields a few DIFFERENT Constantines from Catholic sites, and many references from Orthodox sites. Catholic sites do not refer to the Roman Emporer as a Saint.
Now, I thought you were citing someone else's work, when I called it shameless. Someone who published his work should have done their homework to know that edits were perverting the text. Since you're not a scholar, I will rescind the comment about "shameless," and simply recommend you do a lot more learning about Catholic church history from a lot better sources before you see fit to edit the writings of a saint, and tell you that those citations do not refer to what you think they refer to at all.
As for other postings I've seen, your conclusion that hyperbole=lie is incorrect. St. Basil is using very strong language to address what is is a very grave problem. And yes! The Catholic Church agreed and stomped out the heresies St. Basil is addressing! What is meant by hyperbole is not a lie: When he says, "the bishops..." he is not meaning every bishop, as one might infer. Therein lies the hyperbole. Rather, he means many bishops, but not all. From the fact that their heresies were eventually suppressed, you can historically deduce that many bishops did not fall for the heresy.
