Hebrews 1:5 For unto which of the angels said he at any time, Thou are my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son?
‘Thou are my Son, this day have I begotten thee.’ This is the first Old Testament prophecy in Hebrews (1:5; Ps. 2:7) and has been fulfilled by His birth. This refers to the incarnation when the second person of the Divine Trinity took a human body to redeem (Php. 2:5-11; Isa. 7:14; 9:6). It was when God had a Son through Mary (Matt. 1:18-25; Luke 1:35; John 1:14). This happened on a certain day: “This day have I begotten thee” (Heb. 1:5-7). Therefore, we cannot say that God had a Son before this time. This proves that sonship in connection with God had to refer to humanity and not to deity.
As God, the person we now know as Jesus Christ had no beginning, was not begotten, was not a Son, and did not come into being. He always existed as God (Ps. 90:2; Mic. 5:2; John 1:1-2; Heb. 1:8). But as man and as God’s Son He was not eternal. He had a beginning. He was begotten – at the same time Mary had a Son. Therefore, the doctrine of the eternal sonship of Jesus Christ is irreconcilable to reason, unscriptural, and contradictory to itself. Eternity has no beginning, so if He has been God from eternity, then He could not have a beginning as God. Eternity has no reference to time, so if He was begotten “this day,” then it was done in time and not in eternity.
The word Son supposes time, generations, father, mother, beginning, and conception – unless one is a son by creation, as Adam (Luke 3:38), and angels (Job 1:6; 2:1; 38:7; Gen. 6:1-4). “Time, created, and beginning,” are opposites to God and eternity and are absolutely impossible to reconcile with them. If sonship refers to deity, not to humanity, then this person of the Deity had a beginning in time and not in eternity. It is plainly stated in Psalms 2:7; Acts 13:33 and Hebrews 1:5; 5:5 that God had a Son “this day” and not in eternity. It is stated in Hebrews 1:5-7; Luke 1:35 and Matthew 1:18-25 when this took place. It was nearly 2,000 years ago. It had been predicted that God would have a Son (Isa. 7:14; 9:6; Heb. 1:5; Matt. 1:18-25; Luke 1:32-35). This was fulfilled when the virgin conceived “of the Holy Ghost” (Matt. 1:20), not at any other time. To say that God had an eternal Son would mean He had two; but it is plainly stated that Jesus was “the only begotten of the Father” (John 1:14, 18; 3:16-18; 1Jn. 4:9).
‘I will be to him a Father, and he shall be to me a Son.’ This is the 2nd Old Testament prophecy in Hebrews (1:5; 2Sam. 7:14) and was fulfilled when Christ was born.
