It literally depends on the church you go to. Almost all praise and worship God first, and then learn lessons from scripture. Some churches have Bible study groups or other small groups for fellowship. The culture, friendliness and conservatism varies by church. If the church teaches things that are not in the Holy Bible, then leave and find a Bible-based church.
It would be in poor taste, but a summons can be issued anywhere they expect you to be.
Expect to feel pretty stupid and to cringe a lot. Expect people to be freakishly nice to you in the hopes that you'll join their flock and validate their existence. Expect to leave there questioning the existence of God. Good luck!
