This is your personal experience... You can't read to much into certain contacts or conversation you had. I see no pre or post-VAT II teachings here. Quite frankly, it's not conclusive anyway. Where do you get confirmation that she was a prostitute in this post? Certainly HMiS seems to think so, but where does he find his certainty other then through a tought process. Certainly no hard facts. She was a Sinner (not sure what a "deep" sinner his) that Christ embraced, thats all we know for sure.
It's only my personal experience as far as I was laughed at and made fun of because I believed what my mother taught me about Mary Magdalen. Had I learned anything in the post Vat II Church about her, it surely would have been a watered down politically correct version of things, as we see today.
The point in mentioning my mother was that it has always been a Catholic tradition that Mary Magdalen was a whore and repented her sins. This is what the Church taught, and my mother learning it before modernism entered the Church is proof of that. The Church prior to Vatican II was the same everywhere with the exception of the Eastern rite (if I'm wrong someone please correct me!). You could walk into a Catholic Church virtually anywhere in the world and get the same Latin Mass that was said on the other side of the world. You would get the same catechism everywhere, virtually the same traditions with minor differences. That is
not the situation today.
Many priests, bishops, laymen, etc. today, make changes based on their fancy, to be politically correct, to appease other religions, to make the rainbow people happy, to make women happy, some new and "improved" "scholar" said so, etc etc etc. Even John Paul II did it. When something isn't consistent it's hard to know what to believe. I'll rely on what is consistent about the Catholic Church, and to do that I have to go back to pre-VatII.
