马可福音 16:19

So then the Lord Jesus, after he had spoken to them, was received up into heaven, and sat down at the right hand of God.

In the year 177 A.D., Irenaeus quoted this verse and another from the beginning of this gospel, thus proving that this passage was received as a part of God's word at that early date, long before the Sinaiticus or Vaticanus manuscripts were written, and indicating the rightful place of this portion of Mark in the sacred canon, independently of these manuscripts. See the introduction.

Here Mark did not state exactly where the ascension occurred; and the alleged contradictions regarding this event as having occurred in Galilee, or in Bethany, are of no weight at all. There is every likelihood, if not certainty, that the actual ascension to God was unseen by human eyes, just as the resurrection was not actually seen; and there could have been more than one (there certainly were) instance of Jesus' "going up" in the presence of his disciples, just as he disappeared in the interview with the disciples at Emmaus, or later with the eleven.

At the right hand of God ... Our flesh, in the person of Jesus, is upon the throne of God, henceforth called the "throne of God and of the Lamb," and herein is the basis for the uttermost of human hopes and aspirations.
