I honestly wouldn’t go as far as saying Satan “infiltrates” I think that sort of gives the impression that the church can be ruled or dictated by Satan at a certain point. Satan definitely tries and there definitely are judases especially from the modernists who’ve actually infiltrated the church and have pushed for homosexual priests to be priests, funny the pedo cases all arose when all these modernists started playing with that crap.Even though we belivers know that satan inflitrates the Church at times, I wouldn't hold my breath if I were you.
As for what I stated above about the rift brewing in the church I’m surprised you haven’t heard about that. A lot of bishops and stuff have grown tiresome of pope Francis’ vague language that may lead to heresy. But some took it too far by saying he’s not a legitimate pope, that’s just slanderous as hell and absolutely no evidence. The only evidence is he was legitimately elected by the conclave and Benedict has officially resigned and is not the true pope in the shadows otherwise he would’ve come out explicitly stating just that. I must say, while I side a lot with the traditionalists on church matters they become a little bit like leftists in 2016 screaming “not my president”.
