God spoke through the prophet 700 years before Christ and said His people would be called by a “new name that the mouth of the Lord will bestow” (Isaiah 62:2). The only new name for God’s people is Christian. This name appears 3 times in the Bible: Acts 11:26; 26:28; I Peter 4:11. God gave this new name and we must not add anything to it (I Cor. 4:6; 2 John 9; Rev. 22:18-19).
We violate God’s will when we add to His perfect Word, when we call ourselves “this or that kind of Christian.” A certain method should be followed, but we must not be Methodist-Christians. We baptize believers, but God’s name is not Baptist-Christians. God’s church is universal, but we are not Catholic-Christians. His church leaders are called presbyters (elders), but we do not wear the name Presbyterian- Christians. Since I believe in certain facts does not justify my being a “Holiness – Baptist – Episcopalian – Gateway – Adventist – Congregational – Jehovah’s Witness – Pentecostal” kind of a Christian.
Martin Luther said not to wear his name. Charles Spurgeon said not to wear the name Baptist. In churches of Christ, you can be a Christian only!
