Bede — on Rev 4:4 (Commentary on Revelation)

“And around the throne were twenty-four thrones, etc. He sees the same Church, which he had seen as one seat because of the fellowship of faith, generated from the patriarchs and apostles through the double testament, in twenty-four thrones, sitting because of its judicial dignity in Christ. For all members will sit and judge, but in one and through one head. For how can the saints sit in judgment, standing at the right hand of the Judge? The twenty-four elders can also be understood as those who complete the perfection of work, which is commended by the number six, with the clear preaching of the Gospel. For four times six makes twenty-four.”
