Begotten does not mean created.
Monogeneses is translated (1) “only” in (1a) Lk 7:12 of the widow of Nain’s son; (1b) Lk 8:42 of Jairus’ daughter; (2) “only-begotten” (2a) of Jesus in Jn 1:14, 18; 3:16, 18; 1 Jn 4:9; (2) of Isaac in Heb 11:17; and (3) “only child” in Lk 9:38 of the devil-possessed child.
(4) With reference to Christ, the phrase “the only begotten of (from) the Father,” Jn 1:14, indicates that as the Son of God He was the sole representative of the Being and character of the One who sent Him. (4a) In the original the definite article is omitted both before “only begotten” and before “Father,” and its absence in each case serves to lay stress upon the characteristics referred to in the terms used.
(4b) The apostle’s object is to demonstrate what sort of glory it was that he and his fellow apostles had seen. (4c) That he is not merely making a comparison with earthly relationships is indicated by para, “from.” (4d) The glory was that of a unique relationship and the word “begotten” does not imply a beginning of His Sonship. (4e) It suggests relationship indeed, but must be distinguished from generation as applied to man.
(5) We can only rightly understand the term “the only begotten” when used of the Son, in the sense of un-originated relationship. (5a) The begetting is not an event of time, however remote, but a fact irrespective of time. (5b) The Christ did not become, but necessarily and eternally is the Son. He, a Person, possesses every attribute of pure Godhood. (5c) This necessitates eternity, absolute being; in this respect He is not ‘after’ the Father;
(8) In Jn 3:16 the statement, “God so loved the world that He gave His only begotten son” must not be taken to mean that Christ became the only begotten son by incarnation. (8a) The value and greatness of the gift lay in the Sonship of Him who was given. (8b) His Sonship was not the effect of His being given. (Strong and Vine’s, 167)
Hebrews 1:5 also argues against the Jehovah's Witnesses’ “procreation definition” because “begotten” is used with reference to the enthronement of the existing Christ; an Old Testament parallel to Psalm 2:6-8.
Lastly, even an English definition of “beget” as applied to Christ means to bring into a special relationship, and not by procreation.
(10) Beget in English means to bring into a special relationship. The “be” is intensive and “get” means to bring to one’s self. Jesus, as “the only-begotten of the Father” means that even though he had the unique and equal relationship within the Trinity in eternity past, He took upon Himself the likeness of sinful flesh, dwelt among men, was tempted in all ways, yet without sin, submitted to the death on the cross, was raised on the third day, and ascended to the right hand of the Father. He was always uniquely related to the Father, but even more so now as He is the only unique Son of God, the only sacrifice to remove sins and restore fallen man to God.
