A Prayer on St Thomas Sunday (Antipascha)
Thou hast made us to stand in Thy tabernacle, and hast opened Thine habitation to us, O Holy One, putting in our mouths the triumphal hymn; Thou hast made us to rejoice in Thy most pure and holy Body; Thou hast given us drink of Thine inexhaustible font, from Thy most pure and life-giving side; which, when he had seen, felt and adored, the Apostle Thomas cried out: My Lord and my God! And what return shall we give Thee, O Master, for all Thou hast given us? But Thyself, O mighty King of All, vest in righteousness Thy priests who live by the Orthodox faith; strengthen the Orthodox Christians against all adversaries; preserve in peace the people here present; humble the nations, return the captive Christians our brethren, and give peace to Thy world, O God our Savior. For to Thee belongeth all glory, honor, thanksgiving and worship: together with Thy Father Who is from everlasting, and Thine All-Holy, and Good, and Life-creating Spirit, now and ever, and unto ages of ages. Amen.
From an ancient Ambon Prayer (Orlov, Prayer No. 62, pp. 348-9)
