Cephas of Iconium Wikipedia
Cephas of Iconium is numbered among the Seventy Disciples, and was bishop of Iconium or Colophon, Pamphylia. It is assumed that he is the one who is mentioned by the Apostle Paul (1 Cor. 15:5). The name "Cephas" is Aramaic for "Peter."
The Church remembers St. Cephas on March 30 with Apostles Sosthenes, Apollos, Caesar, and Epaphroditus; and on December 8 with the same apostles and Onesiphorus. Apostles of the 70 were chosen and sent by Jesus Christ himself to preach. They were chosen some time after the selection of the Twelve Apostles. All seventy are commemorated by the Church on January 4.
