Reading from the Synaxarion:

Longinus the Centurion

This Martyr was in the service of Pontius Pilate at the time of Christ our Saviour's Passion. While standing guard at the Cross and beholding the earthquake and all that came to pass, he cried out with fear, "Truly this was the Son of God" (Matt. 27:54). After the Resurrection, he forsook the military and departed for Cappadocia, his homeland, where he preached Christ. By the agency of Pontius Pilate, Tiberius Caesar had him arrested and beheaded.
