Apostle Caesar

The holy, glorious, all-laudable Apostle Caesar is numbered among the Seventy Apostles , and was bishop of Dyrrhachium, a district of the Peloponnese in Greece.
The Church remembers St. Caesar on March 30 with Apostles Sosthenes , Apollos , Cephas , and Epaphroditus and on December 8 with the same apostles and Onesiphorus .
Apostles of the 70 were chosen and sent by the Lord Jesus Christ himself to preach. They were chosen some time after the selection of the Twelve Apostles ( Luke 10:1-24). All seventy are commemorated by the Church on January 4 .
