Victorinus of Poetovio
The opening of the seals, as we have said, is the disclosure of the prophecies of the Old Testament and the foretelling of what will happen in the future. Although the prophetic Scripture speaks through the opening of each separate seal, the prophecy receives its order when all the seals are opened together. One of the living creatures is mentioned because all four are one. Come and see: come is said to those invited to faith, and see to him who had not seen.
