Two articles out of many of a recent controversy between theologians concerning the doctrine of the Trinity and the eternal submission or subordination of the Son in His role and function to the Father. (not subordinate in nature/substance/essence or power, but in role and function.)
Evangelical theologians who seemed to affirm an eternal subordinate relationship of the Son to the Father. by Wayne Grudem
The first one by J. I. Packer caught my eye; and also, other famous theologians. Be sure to read them all. The whole discussion is very interesting and the deeper one goes, the deeper one is pushed to think even more deeply about these things.
1. J. I. Packer, Knowing God (1973). (Packer is probably the best-known living evangelical theologian, and is sometimes called “the gate-keeper of evangelicalism.”)”Part of the revealed mystery of the Godhead is that the three persons stand in a fixed relation to each other….It is the nature of the second person of the Trinity to acknowledge the authority and submit to the good pleasure of the first. That is why He declares Himself to be the Son, and the first person to be His Father. Though co-equal with the Father in eternity, power, and glory, it is natural to Him to play the Son’s part, and find all His joy in doing His Father’s will, just as it is natural to the first person of the Trinity to plan and initiate the works of the Godhead and natural to the third person to proceed from the Father and the Son to do their joint bidding. Thus the obedience of the God-man to the Father while He was on earth was not a new relationship occasioned by the incarnation, but the continuation in time of the eternal relationship between the Son and the Father in heaven.” Knowing God (Downers Grove, IL: InterVarsity Press, 1973), 54-55.
