The feast of Abraham recalls the person, our father in monotheistic Judaism who opened the door to human faithfulness before the holiness of a God who revealed Himself to humanity in a new way. The holy Patriarch’s liturgical memorial is not celebrated in the Latin Church but in the Byzantine Church does so today. He is, however, recalled in the Roman Canon of the Mass and in several of the prayers used during the year. What we believe, and why we pray is expressed in the hymn texts of the Divine Liturgy. By looking at the liturgy we know what we believe and how to live. Here, the holy Patriarch Abraham is extolled a light to follow and a man of God who mediates for humanity before the Throne of Grace.
In the night universal of ignorance towards God, and in that starless, profound gloom bereft of heavenly light, you, O Abraham, were kindled in the firmament, burning with bright far-shining faith in the Everlasting light. Who shines forth to us from your seed, entreat Him with fervor, that He enlighten us and save our souls. (Troparion, Tone 1)
You were a servant, a mortal fashioned from the earth, your master was God, Lord and Fashioner of creation, yet, well-pleased to glorify your celestial greatness, the Lord of all called Himself the God of Abraham Procure for us mercies from your merciful God. (Kondak, Tone 2)
