The Preface of the Apostles
[P] World without end.
It is truly meet and just, right and availing unto salvation, humbly to pray Thee, O Lord and eternal Shepherd, to abandon not Thy flock; but through Thy blessed Apostles to keep a continual watch over it; that it may be governed by those same rulers, whom Thou didst set over it as shepherds and vicars. And therefore with angels and archangels, with thrones and dominions, and with all the heavenly hosts, we sing a hymn to Thy glory, saying without ceasing:
[All] Holy, Holy, Holy, Lord God of hosts.
