The truth is that these words (in Psalm 110) cannot have been spoken about any ordinary man. The saints will sit down together with Christ, their head and representative, and will be on the throne with him in glory, but they are never said to sit at God's right hand. It cannot be an angel either. The writer to the Hebrews rules this out when quoting it (1:13). “To which of the angels did God ever say” such things? Rather, angels and powers are subject to him who is at the right hand (1 Peter 3:22).
