Simon the Zealot
Apostle, Σίμων ο Ζηλωτής
The Holy Apostle Simon the Zealot was one of the Twelve chosen by the Lord. The Gospels record his name among the Apostles, and his title of Zealot bespeaks his burning devotion. After Pentecost he went forth like the others to preach the Gospel, and tradition holds that he carried the good news to distant lands and completed his course as a martyr.
