St Simon was from Cana in Galilee, and was known to the Lord and the Theotokos. Tradition says that he was the bridegroom at the wedding where the Saviour performed His first miracle. After witnessing the miracle of the water which had been turned into wine, he became a zealous follower of Christ (John 2:1-11; Luke 6:15). St Simon was also called Simon the Cananite by St Matthew (Matt 10:4). The word "Cananite" used by St Matthew is believed to be derived from kana, which in the Palestinian dialect of Aramaic means "zealot" or "zealous"; St Luke therefore translates the meaning of "Cananite". Simon means "one who hears".
St. Simon was one of the twelve Apostles, and received the Holy Spirit with the others on the day of Pentecost. He travelled to many places from Britain to the Black Sea, proclaiming the Gospel of Christ. After winning many pagans to the Lord, St Simon suffered martyrdom by crucifixion.
St Demetrius of Rostov says that this St Simon is to be distinguished from the Apostle Simon Peter, and from the Lord's relative Simon (Matt13:55), who was the second Bishop of Jerusalem.
St. Simon is also commemorated on June 30 with the other Apostles.
