So, then, no proof whatsoever. That's what I thought.
You can go ahead and just apply that to yourself, and to every other sectarian schismatic among the tens-of-thousands of entirely non-authoritative recently-invented, man-made non-Catholic sects in existence to date, with more popping up every week.
It's you who have no proof. You make up terms just like your denomination run by these 2 Corinthians 11:13-15 KJV. When will you get saved and follow Paul?
Now go ahead and cite the biblical text that states that "Only words specifically and explicitly used in the English Bible may be used by Christians to express their beliefs."
Yes, Paul is exhorting the Corinthian believers, who became Christians under his preaching, to imitate his Christian way of life. Hardly revolutionary, since the New Testament instructs believers to follow and imitate ALL of the apostles.
