Greetings again “The-Plural-One-God”,
The expression “The only begotten GOD” is a contradiction in terms. God has always existed and cannot be begotten. The term the only begotten son refers to the fact that Jesus was conceived by God the Father, his father, in the womb of Mary his mother.
Matthew 1:20–21 (KJV): 20 But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived (mg Gk: begotten) in her is of the Holy Spirit. 21 And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
Luke 1:34–35 (KJV): 34 Then said Mary unto the angel, How shall this be, seeing I know not a man? 35 And the angel answered and said unto her, The Holy Spirit 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.
John 1:14 (KJV): And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
John 1:18 (KJV): No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.
John 3:16 (KJV): For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
