Contradiction with Acts 1:9
Luke 24:50 describes Jesus leading the disciples to Bethany before ascending, but Acts 1:9 specifies the Mount of Olives as his ascension point.
Acts 1:9: And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight.
Contradiction with Luke 24:51
Luke 24:50 does not explicitly mention Jesus' ascension, while Luke 24:51 states he was carried up into heaven from Bethany.
Luke 24:51: And it came to pass, while he blessed them, he was parted from them, and carried up into heaven.
