Saint Romanos Melodios (?-c 560) composer of hymns - Hymn “ To the newly baptized ”, str. 1, 4-5.19 (cf. SC 283, p. 343f.)
See, you are created anew, O newly baptized one! See, you are made new! Bend your back no longer beneath your sins. The cross is yours for support; lean upon it. Take it into your prayer, to your table, to your bed; take it everywhere as your title to glory (…) Shout at the demons: “With the cross I my hand I stand erect, holding dear our Resurrection.” - Glory to you, glory to you, for such was your good pleasure.
