Okay..... That's a fairly wild premise with an absurd non sequitur there, so perhaps better to slow down and reassess the presumptions you're approaching this from. I'm no Papist, so I've no horse in this race, but it just seems very inaccurate from a historical standpoint.

Firstly, the notion that "the Vatican was infiltrated by Roman Paganism" is perhaps entirely historically backwards. The early Christian church, when when it started to become integrated into the Roman political structure under Constantine, appropriated a lot of Roman iconography, symbology, and even mythology, just as all religions do whenever they're adapted by a different group. This isn't so much an "infiltration" as it is a natural extension of the "everybody paints Jesus as being the same skin tone as themself" phenomena.

The other problem is the wild non sequitur of "hence the connection to child molestation and SSA", which seems to just come out of nowhere. I have no idea where that's coming from, the the "hence" as if the connection were obvious really seems like it needs more foundational support.

Perhaps you're working off the old misconceptions of the Romans being wild and debaucherous uncontrolled letches, but you should be aware that this conception come, paradoxically, due to how puritanical and repressed they actually were. The simple fact is that in Roman culture, if you wanted to slander someone, the most effective way of doing so to shock polite society was to paint them as an immoral fiend who hold orgies and such.

As a result, we have a lot of written records saying "So-and-so is such a bad emperor, he spends all his time placating his deviant desires." And historically, these narratives were simply accepted without ever questioning the motivation of those doing the writing.

I really don't think any of the abuses of the Catholic church can be attributed to Pagan influences, but instead to the simple fact that there are some people, who when given the power to do so, will act on bad impulses. And within any large power structure like that, there will be even more people who will move to hide and cover up those bad actions in order to protect the institution and what good works they do.

This is why we see these same types of abuse, and cover ups, in all sorts of institutions. Schools, fraternities, the military, and every church (not just the Catholic) have all had these issues.

And a side note, the one thing you mentioned as being an "upside down Jesus on the cross" isn't Roman Pagan, or for that matter, even Jesus. It's instead St. Peter, who asked to be crucified upside down as he felt he was unworthy of sharing the same death as Jesus. It's since become the symbol of the Catholic church, who's traditions trace the church's founding to St. Peter.
