Ticonius — on Rev 4:4 (COMMENTARY ON THE APOCALYPSE 4:4)

“The elders represent the whole church, as we learn through Isaiah, "The Lord has reigned in Zion and in Jerusalem, and he will be glorified in the presence of his elders." However, the twenty-four includes at the same time both leaders and people, as though duplicating the twelve tribes of Israel on account of the two Testaments. For the very same church is established in both the old and in the new, since he shows the church in the twelve apostles, namely, the entire body of leaders. And so we discover Jerusalem in the description of the city descending from heaven. The twenty-four thrones, considered by way of a distribution of offices, are twelve, since also the leaders of the twelve tribes will be advanced. And the twelve thrones, considered by way of a mystical number, is one throne, where from comes the church. For the Lord Christ is alone the one who will sit in judgment. However, the church also will sit and does sit judging the twelve tribes, but she will do this in Christ in whom is the whole [church]. Therefore, the members will sit and judge, but in one head and through one head.”
