Power is an entity's or individual's ability to control or direct others, while authority is influence that is predicated on perceived legitimacy. Encyclopaedia Biblica Volume 1, page 473--1899 edition under Formula "In the name of Jesus Christ or of the Lord Jesus. The former expression is used in Acts 2:38 and 10:48. The latter is used in Acts 8:16 and 19:5. See also Acts 22:16... From these passages, and from Paul's words in the 1st Corinthians 1:13 ('Was Paul crucified for you, or were ye baptized in the name of Paul?), it is natural to conclude that baptism was administered in the earliest times 'in the name of Jesus Christ', or that 'of the Lord Jesus.' This view is confirmed by the fact that the earliest forms of the baptismal confession appear to have been single--not triple, as was the later creed."
