The Preface of the Sacred Heart
[P] World without end.
It is truly meet and just, right and availing unto salvation, that we should in all times and in all places give thanks unto Thee, O holy Lord, Father almighty, and everlasting God; who didst will that Thine only begotten Son should be pierced by the soldier's lance as He hung upon the Cross: that from His opened heart, as from a sanctuary of divine bounty, might be poured out upon us streams of mercy and grace; and that in His heart always burning with love for us, the devout may find a haven of rest, and the penitent a refuge of salvation. 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.
