And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.
Misinterpretation: This Scripture is used to teach that baptism in the Name of Jesus is necessary. The logic is that we are supposed to do everything in the Name of Jesus, and everything includes baptism. UPC preachers often go on to say that Trinitarian preachers will pray in the Name of Jesus, marry in the Name of Jesus, and do many other things in the Name of Jesus, but that they will not baptize in the Name of Jesus.
Facts: First, this Scripture has nothing to do with baptism. Paul is writing about living a godly life, and he is reminding people that they need to do everything "in the name of the Lord Jesus." One could think of this as an ancient "WWJD" saying. Paul was reminding the Colossian church to always live their lives in a way that is pleasing to God (cf. Col. 3:8-17). Second, the UPC forgets that Trinitarian preachers are obeying Jesus when they baptize in the Name of the Father, Son, and Holy Ghost [see my notes on Mat. 28:19].
