Part II Denominations are unscriptural because they were founded by men, have human heads, have human creeds, wear human names, and follow men. The church was founded by Christ. Christ is also the head of the church. We are to use it for teaching, correcting, and training. Denominations follow human creeds which God's word warns against.
Denominations also wear human names glorifying some person, place, event, or philosophy.
Following men is condemned in the Bible. Many of that time were naming their churches after men such as Paul, Chephas, and Apollos. Paul was telling them that this was wrong because it did not put Christ first and also caused divisions among them. Denominations are unscriptural because they do not require membership for salvation. A big problem with denominations is that they preach contrary gospels.
