So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God.
All Commentaries on Mark 16:19 Go To Mark 16
Tertullian of Carthage
AD 220
It is the Son, too, who ascends to the heights of heaven, and also descends to the inner parts of the earth. “He sits at the Father’s right hand”—not the Father at his own. He is seen by Stephen at his martyrdom by stoning, still sitting at the right hand of God, where he will continue to sit, until the Father shall make his enemies his footstool. He will come again on the clouds of heaven, just as he appeared when he ascended into heaven.
