Apolytikion in the Fourth Tone

Today marks the crowning of our salvation and the revelation of the mystery before all ages. For the Son of God becomes the son of the Virgin, and Gabriel proclaims the grace. Wherefore, we also cry out with him, "Hail, O full of grace, the Lord is with you."

Kontakion in the Plagal of the Fourth Tone

To you, Theotokos, invincible Defender, having been delivered from peril, I, your city, dedicate the victory festival as a thank offering. In your irresistible might, keep me safe from all trials, that I may call out to you: "Hail, unwedded bride!"
