The Westminster Confession violates their own Confession in asserting that "the Son is eternally begotten of the Father."
A great part of the Confession states: "IX. The infallible rule of interpretation of Scripture is the Scripture itself:" Too bad they did not follow this rule of interpretation in so many places and particularly in this heresy of eternal sonship.
The Bible makes it clear, the WORD was NOT born a son until he was born a son in Bethlehem.
Luke 1:35 And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.
Dake notes:
b [Son of God] Sonship with Christ always refers to humanity, not to deity. As God, He had no beginning (Mic. 5:2; Jn. 1:1-2); was not begotten or He would have had a beginning as God; and was not God's Son. But as man, He had a beginning, was begotten, and was God's Son (Ps. 2:7,12; Mt. 1:18-25; Lk. 1:35; Heb. 1:5-6). In these passages it is clear that there was a certain day when God was to have a Son and the Son have a Father. It was to be in the future from the time the prophets spoke. If sonship refers to deity, then this deity had a beginning on a certain day and He was not eternal. But if it refers to humanity, then all scriptures are clear and we have no man-made mystery of the so-called eternal sonship of Jesus Christ. If it refers to both deity and humanity, then when did He become God, when was He begotten, how could He have been eternal? If He had a beginning and was begotten then He was not, nor is He, an eternal God. If He was a son of God by creation, then He is no greater than angels and other beings who had beginnings. Multiplied problems increase and become unanswerable with Scripture if we hold to the theory of eternal sonship, but all questions are clear when we accept the plain statements of Scripture that sonship refers to humanity and not to deity.
