Some Evangelicals, such as John MacArthur, J. Oliver Buswell, and the late Walter Martin, have been abandoning the Trinitarian faith as defined by the First Council of Nicaea (A.D. 325).
Their abandonment of orthodox Trinitarianism consists in denying the eternal Sonship of Christ, the doctrine that the second person of the Trinity was the Son of God from all eternity.
Instead, they claim that the second person of the Trinity only became the Son of God at his incarnation. Apart from the incarnation he was still God, but not the Son, just the second Person.
This teaching destroys the internal relationships within the Trinity, because if the Son was not eternally begotten by the Father then neither did the Spirit eternally proceed from the Father through the Son. It also destroys the Fatherhood of the first person, since without a Son there is no Father.
Thus the fundamental familial relations among the persons of the Godhead are destroyed and replaced by mere social relationships, a bare existence of three persons in the Godhead.
The Church Fathers who wrote the creeds had a different view.
This tract presents a collection of quotes from the early Church Fathers demonstrating the eternal Sonship of Christ.
