We may have very different understandings of free will vs predestination, covenant theology vs premillenialism, church structure, etc., but we share a common faith and an indwelling Holy Spirit. The differences make for interesting discussions, but they are only matters of discernment not salvation.
Unfortunately, your church has taken a different road and you are separated from the Body of Christ because of it. The good news is you can throw off that man made yoke of works, legalism, rituals, and submission to men anytime and join the Body of Christ by having Faith Alone in Christ Alone.
AMEN!
