"As beholders and martyrs of the incarnation of the Logos..."

The Synaxis of the Holy Twelve Apostles of Christ (source)

  
As beholders and martyrs of the incarnation of the Logos, O all-joyous and blessed Disciples, you shine throughout the world like lightning, and you stand like noetic mountains that pour forth streams of sweetness, and like never-emptying, spreading rivers from Paradise, you water the Church of the nations with divine waters.
-Prosomoion from Great Vespers from the Feast of the Holy Apostles

Through the prayers of our Holy Fathers, Lord Jesus Christ our God, have mercy on us and save us! Amen!
