Contradiction with Exodus 33:20
This verse states that no one can see God's face and live, whereas Luke 1:78 discusses the "dayspring from on high" visiting us, implying a more direct revelation of God to people.
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
John states that no one has seen God at any time, which seems inconsistent with the notion of God visiting us found in Luke 1:78.
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
This verse repeats the idea that no one has seen God, creating a contradiction with the imagery of divine visitation in Luke 1:78.
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.
