O most merciful God, Who when the holy Abbot Sylvester stood within an open tomb, meditating on the transitory vanities of this world, wast pleased to summon him into the wilderness and make his life illustrious by signal virtue: we earnestly beseech Thee, that like him, we may despise earthly things, and enjoy communion with thee forevermore. Through our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, one God, world without end. Amen.
(Roman Breviary)
