And he went up on the mountain, and called to him those whom he desired; and they came to him. And he appointed twelve, to be with him, and to be sent out to preach and have authority to cast out demons.

Mark 3:13-15

"Everlasting God, to whom all hidden things are revealed, who sent into the world Your Only Begotten Son, our Lord Jesus Christ, conceived through the Holy Spirit, born of the Virgin Mary, that He might take on Himself the punishment of our sins and by His resurrection, snatch us from the gates of hell, grant to our hearts such steadfastness of faith that confessing Christ, Your Son, we may not perish but may be joined to Him in the confession of Your Holy Name. Amen."

– Prayer of St. Vincent of Saragossa
