5th Saturday of Great Lent: of the Akathist to the Theotokos - Troparion & Kontakion
Troparion — Tone 8
When the archangel understood the mysterious command, / he came to the house of Joseph with haste and proclaimed to the unwedded Lady: / The One Who bowed the heavens by His condescension / is contained wholly and without change in you! / As I behold Him in your womb, taking the form of a servant, I am frightened, but cry: / Rejoice, unwedded Bride!
Kontakion — Tone 8
Victorious leader of triumphant hosts, / we your servants, delivered from evil, sing our grateful thanks to you, Theotokos! / As you possess invincible might set us free from every calamity, / so that we may sing: Rejoice, unwedded Bride!
