Contradiction with Exodus 33:20
God is described as invisible in 1 Timothy 1:17, but in Exodus 33:20, it is said that no one can see God and live, suggesting that God can be seen, albeit with severe consequences.
Exodus 33:20: And he said, Thou canst not see my face: for there shall no man see me, and live.
Contradiction with John 1:18
1 Timothy 1:17 describes God as invisible, while John 1:18 states that no one has seen God at any time, yet the only begotten Son has declared Him, implying a form of visibility through Jesus.
John 1:18: No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared [him].
Contradiction with 1 John 4:12
Contrasts with 1 Timothy 1:17 by reiterating that no one has seen God at any time, potentially contradicting the idea of God's invisible attributes being comprehended.
1 John 4:12: No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.
Contradiction with Genesis 32:30
Jacob claims to have seen God face to face, which contradicts the notion in 1 Timothy 1:17 of God's invisibility.
Genesis 32:30: And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved. [Peniel: that is, The face of God]
Contradiction with Isaiah 6:5
Isaiah claims to have seen the Lord, which appears to contradict the assertion of God's invisibility in 1 Timothy 1:17.
Isaiah 6:5: Then said I, Woe [is] me! for I am undone; because I [am] a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts. [undone: Heb. cut off]
