Contradiction with John 1:18
This verse states that no one has seen God at any time, which contradicts the idea in Deuteronomy 5:4 that God spoke face to face with the people.
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 Exodus 33:20
God states that no man can see Him and live, which contradicts the notion of face-to-face communication in Deuteronomy 5:4.
Exodus 33:20: And he said, Thou canst not see my face: for there shall no man see me, and live.
Contradiction with 1 John 4:12
Affirms that no one has seen God at any time, contradicting the description in Deuteronomy 5:4 of direct face-to-face interaction.
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 1 Timothy 6:16
Declares that God dwells in unapproachable light and no man has seen or can see Him, directly opposing the claim of face-to-face contact in Deuteronomy 5:4.
1 Timothy 6:16: Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom [be] honour and power everlasting. Amen.
Paradox #1
One possible contradiction is that Deuteronomy 5:4 suggests God spoke directly to the people, but other parts of the Bible, like Exodus 20:19, indicate the people were afraid and asked Moses to speak on God's behalf. This creates a potential conflict about whether the people heard God directly or through Moses.
