The triadic formula given in
Matthew 28:19 names the fullness of God. The wording in Matthew 28:19 should
not be described as “trinitarian,” for the term trinity does not enter
the Christian vocabulary until the late second century, and its definition
developed after the term came into use. (Daniel B. Stevick, By Water and the
Word: The Scriptures of Baptism [New York: Church Publishing Incorporated,
1997], 165-66)
