The best way to know if a Lutheran congregation is right for you (and, for obvious reasons, everyone here thinks it is!) would be to compare what you read, especially in the Small Catechism, with what you read in the Scriptures. If you end up saying, yes, that’s what the Scriptures teach, then it might be best to seek out a local LCMS pastor and ask him any further questions you might have. He can talk to you about your specific questions and experience, and help point you further in the right direction.
I hope that helps a little.
