Is your faith truly based upon core beliefs or upon something else?
In no possible way, does God want us to enable evil. Supporting an institution that permits evil to run rampant within its ranks and tempts others to follow evil couldn’t possibly be God’s will.
One of those core beliefs is that Christ established ONE Church. His Body. The fact that there are humans who are in that Church and who are charged with stewarding that Church doesn't change that. Look at the example of Christ and St. Peter. When Christ gave him the keys, He knew that Peter would deny Him not that long afterward. What greater evil could there be than that? But look: the same Simon Peter who denied Christ was the same Peter who gave that preached so powerfully on the day of Pentecost, as recorded in the Acts Chapter 2!
You can take a look through the Acts and throughout St. Paul's writings and see the effects of human frailty throughout. In fact, you can see in one of St Paul's letters that some of the particular churches that make up the Church were not without their own problems. Especially 1 Corinthians. Especially chapter 5. But it's also in that same letter where Paul calls to unity (1 Cor 3) and teaches on the Body of Christ in great detail (1 Cor 12). What he didn't write about was people separating themselves, despite the fact that there was grave evil going on in the Church in Corinth.
Like I said earlier, I'm not trying to suggest you come back. Better for you to be docile to the Holy Spirit. But your prayers for the health of the Church are appreciated *AND NEEDED*, whether you wish to be in communion with her or not.
