The word "denominate" means to call or name.
There is a lot of biblical evidence against taking names.
Paul forbids taking names here:
1 Corinthians 1:12 "12Now I mean this, that each one of you is saying, “I am of Paul,” and “I of Apollos,” and “I of Cephas,” and “I of Christ.”
13Has Christ been divided? Paul was not crucified for you, was he? Or were you baptized in the name of Paul?
14I thank God that I baptized none of you except Crispus and Gaius, 15so that
no one would say you were baptized in my name"
Taking only Gods or Christ's name is found in many places:
2 Chronicles 7:14 "if my people, who are
called by my name ....
Acts 4:12 "Neither is there salvation in any other: for there is
none other name under heaven given among men, whereby we must be saved."
Acts 11:26 "And the disciples were called
Christians first in Antioch."
When a person says "I was baptized as a Catholic", or "I am baptized as a Lutheran", they are taking another "husbands" name, which Paul condemns.
If your wife takes another surname other than yours, it means she is unfaithful.
Remember the church is a kind of "bride of Christ" and so taking another name except Christ is like your wife taking another man's surname.
I believe that God feels offended when His people take a name other than His name, just as you would be offended if your wife decided to take another man's name. God has feelings and gets jealous etc as the Bible says.
That is why God hates denominations. Denominations are a sin.
