This may sound shocking to many but the concept of denominationalism (many different churches, teaching many different doctrines) is not taught or sanctioned in the New Testament. Jesus promised and did build "one body" or church (Matt. 16: 18, Eph. 1: 22, 23, cp. Eph. 4: 4). The concept of many different churches was absent in the First Century. Paul, therefore, taught "every where in every church" (I Cor. 4: 17). Denominationalism is division personified. The closest that we can come to denominationalism in the New Testament is the divided state of the church at Corinth. Paul did not praise this fragmented condition, but rather he condemned it. Observe Paul's inspired teaching:
Denominationalism makes Jesus an incompetent Lord. Denominationalism, in view of the conflicting teaching and practices, would have us believe that Jesus was unable to present to the world a Book that all could understand and understand alike. However, the problem is not the Lord's inability, but the problem is man's unwillingness to accept what is taught in the Bible. This is why creeds, dogmas, and confessions of faith in addition to the Bible are needed. Many religions also exist only based on the "authority" of latter day revelation, a matter strictly forbidden (Jude 3).
