Saints Apollos, Cephas, Tychicus, Epaphroditus, Caesar, 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).
St Apollos (September 10) was a native of Alexandria and was a man of erudition. The chief place of his service was at Corinth. He toiled there for a long time and converted many to Christ. Towards the end of his life he preached on the island of Crete and was Bishop of Caesarea.
