Denominationalism is inherently and fundamentally wrong. Jesus came to earth, fulfilled prophecy, performed miracles, established that he was the Messiah, died on the cross, was resurrected the third day, ascended back to the Father, and was received into glory. He promised to build His church (Mt. 16:18). On the day of Pentecoat, following His death, burial, and resurrection of Christ, the church came into being and three thousands obeyed the gospel on that day (Acts 2). You did not find on denomination located at this corner, and another denomination at that corner, in Jerusalem or elsewhere. Paul was not a Baptist preacher, and Barnabas a Methodist preacher, and Peter a Catholic priest (or pope). There was one body and one faith (Eph. 4:4-6). DARRON STEELE WROTE: Denominationalism is division, its not about whether we do things the same way or that we agree about doing things the way we want to. It is about doing things the way God commanded us to do things. As for "silly non-scripture notion"(s) scripture itself teaches us that division is wrong, that we are to be of one mind, this would pertain to doctrine, worship, and living. Shall I start to show the essential issues that divide all the major denominations. They divided because of important issues, they did not divide because one like this type of music and the other this one. They all divided because they could not agree on the three issues stated above. All you have to do is study the denominations and their beliefs and you can see this.
