The belief of the centurion in Christ as the Son of God happened after a miracle. The Gospel according to our teacher St. Matthew says: "Now when the centurion and those with him, who were guarding Jesus, saw the earthquake and the things that had happened, they feared greatly, saying, 'Truly this was the Son of God!"' (Matt. 27:54); (Mk. 15:38,39) When they saw the miracle of the earthquake and the darkness that came over the whole earth from the sixth hour (midday) until the ninth hour, they believed and said: "Truly this was the Son of God!" They meant the Sonship which has dominion over nature and that is why the Gospel says: "they feared. " Maybe their faith was strengthened when they saw blood and water coming out of His side when the soldier pierced Him (Jn. 19:34).
