In Acts, it indicates that Jesus and his disciples were in Jerusalem at His Ascension, and in the Gospel of Matthew, it indicates that they were in Galilee. How does one reconcile the apparent contradiction here?
The Gospel of Matthew cannot contradict the Book of Acts about the Ascension because the Gospel of Matthew does not describe the Ascension. The Ascension is described in Mark, Luke and Acts.
When he had said this, as they were looking on, he was lifted up, and a cloud took him from their sight…Then they returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a sabbath day’s journey away.
- Acts 1:9,12
[But] later, as the eleven were at table, he appeared to them and rebuked them for their unbelief and hardness of heart because they had not believed those who saw him after he had been raised…So then the Lord Jesus, after he spoke to them, was taken up into heaven and took his seat at the right hand of God.
- Mark 16:14,19
Then he led them [out] as far as Bethany, raised his hands, and blessed them. As he blessed them he parted from them and was taken up to heaven.
- Luke 24:50-51
In none of the accounts does the Ascension take place in Galilee. The Mount of Olivet and Bethany are the same area. The Gospel of Mark makes no reference to where the event took place.
