My observation is that we Proddys correct each other on average probably several hundred percent more than RC’s do.
Acts 4:11-12 11 This Jesus is the stone that was rejected by you, the builders, which has become the cornerstone. 12And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.""
It's all about Jesus. He's all we need to be saved.
Differences in worship style, church government, baptism by immersion vs sprinkling, whether women should be pastors or not, even the manifestation of certain gifts of the Spirit, etc, are not essential to one being saved.
