Son Of The Handmaid

Ὦ Κύριε, ἐγὼ ὁ δοῦλος σὸς, ἐγὼ δοῦλὸς σὸς καὶ υἱὸς τῆς παιδίσκης σου. Διέῥῥηξας τοὺς δεσμούς μου. Υἱὸν παιδίσκης φησὶν ἐαυτὸν, τῆς Ἐκκλησίας. Δεσμοὺς δὲ οἷς σειραἶς τῶν ἑαυτοῦ ἁμαρτημάτων κατεσφίγγετο. Ἐλευθερωθεὶς δὲ τῆς ἁμαρτίας, καὶ υἱὸς τῆς σῆς παιδίσκης γινόμενος τῆς Ἐκκλησίας τῶν προτέρον ἀνέθην ἁμαρτημάτων διὰ τῆς σῆς χάριτος. Εὐσέβιος ὁ Καισάρειος, Ὑπομνηματα Ἐις Τους ψαλμους, ψαλμος ΡΙΕ' Source:  Migne PG 23.1360d-1361a

O Lord, I am your servant, I am your servant and son of your handmaid. You have broken my chains. 1 He calls himself the son of a handmaid, that is, of the Church. And the chains by which he was bound were the sins that constrained him. But freed from sin, he is made the son of the handmaid, that is, the Church, liberated from old sins by grace. Eusebius of Caesarea, Commentary on the Psalms, from Psalm 115 1 Ps 115.16
