Arians and Gnostics worked together and corrupted the doctrinal texts. Arians are similar to JW. According to Ante Nicene Fathers, they said, “Only begotten God” had become common with the Arians. We know that Jesus Christ was God, and that Jesus Christ was "begotten" by means of the incarnation, does NOT equal "begotten God.” God the Son, Jesus Christ, became the "only begotten Son" through the incarnation.
The Second Arian Confession said “And in one Lord Jesus Christ, his son, only-begotten god/deity [John 1:18], by whom are all things, who was begotten before all ages from the father, god from God [deity from the Deity]…” Look at the Scripture:
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 1:18 NWT (JW)
No man has seen God at any time; the only-begotton god who is in the bosom (position) with the Father, is the one that has explained him.
John 1:18 (New American Standard Bible)
No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him.
The Greek W/H Text on this verse said:
θεον ουδεις εωρακεν πωποτε μονογενης θεος ο ων εις τον κολπον του πατρος εκεινος εξηγησατο
The Greek word, θεος means, “God.”W/H were also Gnostics and unbelievers.
The Greek Received Text on this verse said:
θεον ουδεις εωρακεν πωποτε ο μονογενης υιος ο ων εις τον κολπον του πατρος εκεινος εξηγησατο
The Greek word, υιος means “Son.”
The Gnostics and Arians favored “begotten God” instead of “begotten Son.” The Arian Creed contained, “only begotten God.” Clement of Alexandria and Origen quoted “begotten Son” and “begotten God.” However they favored ”God” over “Son.” For example, Clement said, “For how shall he not be loved for whose sake the only begotten Son is sent from the Father’s bosom…” And he said, “No one hath seen God at any time. The only-begotten God who is in the bosom of the Father, He hath declared Him.”
Codex Alexandrinus contained, “begotten son.”
Gnostics denied the Jesus was the Christ. They separated Jesus from the Christ. Look at the Scripture:
John 4:42 KJV
And said unto the woman, Now we believe, not because of thy saying: for we have heard him ourselves, and know that this is indeed the Christ, the Saviour of the world.
John 4:42 (New International Version)
They said to the woman, "We no longer believe just because of what you said; now we have heard for ourselves, and we know that this man really is the Savior of the world."
John 4:42 (New American Standard Bible)
and they were saying to the woman, "It is no longer because of what you said that we believe, for we have heard for ourselves and know that this One is indeed the Savior of the world."
John 4:42 (English Standard Version)
They said to the woman, "It is no longer because of what you said that we believe, for we have heard for ourselves,) and we know that this is indeed the Saviorof the world."
Acts 20:21 (King James Version)
Testifying both to the Jews, and also to the Greeks, repentance toward God, and faith toward our Lord Jesus Christ.
Acts 20:21 (New International Version)

Acts 20:21 (Contemporary English Version)

Acts 20:21 (Holman Christian Standard Bible)

A few modern versions contained, “Christ” on this verse. They agree with the KJV.
Romans 16:18 (King James Version)
For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.
Romans 16:18 (New International Version)
For such people are not serving our Lord Christ, but their own appetites. By smooth talk and flattery they deceive the minds of naive people.
Romans 16:18 (New American Standard Bible)
For such men are slaves, not of our Lord Christ but of their own appetites; and by their smooth and flattering speech they deceive the hearts of the unsuspecting.
Romans 16:18 (English Standard Version)

More passages in modern versions showed the separation Jesus from the Christ because of the Gnosticism anywhere today.
