The eternal generation of the Son
Scripture teaches that Jesus Christ is both one with the Father and yet distinct from the Father. The doctrine of the “eternal generation” plays an important role in securing both points. This doctrine teaches that the Father eternally communicates the divine essence to the Son without division or change so that the Son shares an equality of nature with the Father (sharing all the attributes of deity) yet is also eternally distinct from the Father.
Although the eternal generation of the Son is affirmed in early confessions such as the Nicene-Constantinopolitan creed (AD 381) and post-Reformation statements like the Westminster Confession, several prominent evangelical theologians object to this doctrine on the grounds that it lacks biblical support. Evangelicals who reject this doctrine frequently point out that the Greek word monogenes (John 1:18; 3:16) does not mean “only begotten” but rather “unique.” Since the mistranslation of monogenes (allegedly) represents one of key lines of biblical evidence, one should dispense with eternal generation as a theological relic of a bygone era.
In light of this, how should we think about eternal generation?
Keith Johnson offers a fascinating, instructive, and stimulating answer to this question.
