I tend to consider those that preach against the Church Christ established, His Church, to objectively be 'progressive' as defined below. What religious persuasion/group/sect do you belong to -I will be happy to point out the progressive errors you either ignore or are not aware of...
9 Anyone who is so "progressive" as not to remain in the teaching of the Christ does not have God; whoever remains in the teaching has the Father and the Son.
10 If anyone comes to you and does not bring this doctrine, do not receive him in your house or even greet him;
11 for whoever greets him shares in his evil works.
I belong to the church of Jesus Christ, that is, the body of Christ, believers in Him, regardless of sect or denomination or "title". The "church of God, which He bought with his own blood" (Acts 20:28).
And I belong through faith in Jesus Christ, through His atonement on the cross, not because of any sacramental "ticket punching" such as baptism (but rather, in spite of).
Blessings!
