Colossians 1:18-20

(18-20) In these verses St. Paul returns from dwelling on the eternal nature of the Son of God to describe Him in His mediatorial office as Son of Man, becoming the “Head” of all humanity, as called into “His Body, the Church.” In this he touches on a doctrine more fully developed in the Epistle to the Ephesians. (See Ephesians 1:10; Ephesians 1:20; Ephesians 1:22; Ephesians 2:19; Ephesians 2:21; Ephesians 4:15.) But still, as has been already noted, there is in this Epistle more stress on the supreme dignity of the Head, as in the other more on the unity, and blessing, and glory of the Body. It should be observed that in this, His mediatorial office, there is throughout a mysterious analogy to His eternal sonship. In both He is “the Head,” first, of universal creation, next, of the new creation in His Church; He is “the beginning,” in the one case in eternity, in the other in time; He is “the firstborn,” now in Eternal Sonship, now in the Resurrection making Him the new life of mankind.
