Contradiction with John 15:15
Unlike John 5:20, which speaks of the Father showing the Son all things, John 15:15 presents a shift where Jesus refers to the disciples as friends, indicating that everything He has heard from the Father, He has made known to them, which opens the sharing of divine knowledge beyond just the Son.
John 15:15: Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you.
Contradiction with Mark 13:32
In John 5:20, the Father shows the Son all things, yet in Mark 13:32, Jesus states that the Son does not know the day nor the hour, which indicates a limitation in the knowledge the Son has been shown.
Mark 13:32: But of that day and [that] hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
Contradiction with Matthew 20:23
This verse shows Jesus stating that certain positions in His Kingdom are not His to grant, but for those prepared by the Father, which can be seen as a limitation to the autonomy or authority described in John 5:20.
Matthew 20:23: And he saith unto them, Ye shall drink indeed of my cup, and be baptized with the baptism that I am baptized with: but to sit on my right hand, and on my left, is not mine to give, but [it shall be given to them] for whom it is prepared of my Father.
Contradiction with John 8:28
While John 5:20 speaks of the Father's love and revelation to the Son, in John 8:28 Jesus emphasizes that He does nothing of Himself but speaks as the Father taught Him, indicating a dependency on the Father's teaching rather than an independent knowing.
John 8:28: Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am [he], and [that] I do nothing of myself; but as my Father hath taught me, I speak these things.
Contradiction with Philippians 2:6-7
These verses express the concept of Jesus not considering equality with God something to be grasped but emptied himself, contrasting the revealing relationship implied in John 5:20 where the Son sees all the Father does.
Philippians 2:6-7: Who, being in the form of God, thought it not robbery to be equal with God:
Contradiction with Hebrews 5:8
John 5:20 describes a full revelation to the Son by the Father, yet Hebrews 5:8 speaks of the Son learning obedience through suffering, suggesting a process of growth and learning.
Hebrews 5:8: Though he were a Son, yet learned he obedience by the things which he suffered;
Contradiction with John 14:28
Here, Jesus states that the Father is greater than He is, contrasting with the idea in John 5:20 where the Son is shown all things by the Father, indicating a deeper access or equality.
John 14:28: Ye have heard how I said unto you, I go away, and come [again] unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I.
