The Martyrs of Chalcedon were a group of forty-nine Christians slain in Chalcedon during the reign of Emperor Diocletian. Records indicate that the martyrs were members of the choir in the church of Chalcedon.

We do not pray for the martyrs as we pray for those others, rather, they pray for us, that we may follow in their footsteps. We, the Christian community, assemble to celebrate the memory of the martyrs with ritual solemnity because we want to be inspired to follow their example, share in their merits, and be helped by their prayers - St. Augustine
