Welcome brother.
Shop around for churches in your area and use the internet to research the general beliefs of various denominations. You'll obviously want a conservative church that takes the Bible seriously and has an End Times focus.
Try 7th Day Adventist. They're big on End Times stuff. Their apocalyptic predictions have failed more times than I can remember but you can talk about Mystery Babylon and the Pope being a satanist without being seen as a nut.
You could probably get away with this at a Pentecostal church, but they're too weird for me.
Jehovah's Witnesses would be open to it but I keep hearing stories about how them being a cult. Stay away.
Orthodox churches are rare, and I have no experience with them, but they might be worth checking out if there is one in your area. Consider this if you have some attachment to Catholicism but don't want to be led by the false prophet.
Church of Christ (separate from United Church of Christ) believes the more church hierarchy there is, the more likely it is to be comped. The Bible is all they need. Generally a normie church but pillable.
Surely you know about the Baptists. They are everywhere, and they talk to each other, which means the story (if taken) will be more likely to spread. They are very patriotic but they are also hardcore Christian Zionists. Talking about the Jews is a good way to make yourself radioactive with them.
Be sure to join a Bible study. It's a good place to learn, and to drop crumbs. Make a few predictions and get them to trust you more than the Fake News MSM. Then start dropping bombs, like "The cult of Moloch is still around" or "The reason the whole establishment is afraid of Trump is because he DOESN'T eat babies". Good luck.
For background reading, start with the Gospels, Revelation, Genesis, Daniel, and Ezekiel. Listen to Bill Cooper's Mystery Babylon series in the background while doing other stuff:
