St. Simon the Apostle was called the Zealot in the Luke’s Gospel (6:15) and in Acts (1:13). The name indicated his membership in an extremely orthodox Jewish sect. Because he came from Cana, was also called as Canaanite or Cananaean. After Pentecost, like other Apostles he went on missionary work. Some sources say he preached in Egypt, others, that in Persia with Judas Thaddaeus, where they were both martyred. Found guilty in overturning statues of idols, their throats were cut. Though according to another version, Simon was sawn in two, like the prophet Isaiah.
