"You gazed on the divine mysteries of Christ, Apostle Thomas..."

The Holy Apostle Thomas (source)

  

You gazed on the divine mysteries of Christ, Apostle Thomas, and mystically you have been declared to be a spiritual mixing bowl, in which the souls of believers rejoice; for with the divine net of the Spirit you drew peoples from the deep of ignorance; therefore you came from Sion as a river of grace, welling up with your inspired doctrines into the whole creation. And so, imitating the passion of Christ, you were pierced in the side and entered the darkness of incorruption; implore him to have mercy on our souls.

-Doxastikon of the Praises, in the Plagal of the Second Tone

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