Bede, on Rev 5:9

“And they sung a new canticle, saying: Thou art worthy, O Lord, to take the book, and to open the seals thereof; because thou wast slain, and hast redeemed us to God, in thy blood, out of every tribe, and tongue, and people, and nation.”

“And you have redeemed us to God by your blood, etc. Here it is further declared that the creatures and elders are the Church, which has been redeemed by the blood of Christ and gathered from the nations. It also shows in which heaven they are, by saying: And they will reign on the earth. And I saw and heard the voice of many angels around the throne, and the creatures, and the elders.”
