Apostle Apollo

The holy, glorious, all-laudable Apostle Apollo , also Apollos (in Greek: Απολλως), is numbered among the Seventy Apostles . Apollo is a contraction of Apollonius. Apollo was a well educated Jew from Alexandria who was a companion and active missionary with Apostle Paul , particularly in Corinth.
Apparently already well versed in the Scriptures and probably influenced by the teaching of disciples of John the Baptist , Apollo became known to Paul in Ephesus where Aquila and Priscilla spoke with him and instructed him more accurately in the ways of God ( Acts 18:24-28, 19:1-7). Later, he appears as an important personage in Corinth where Paul refers to him as part of the community (1 Corinthians 3:6, and 4:6). That he was an important companion of Paul’s mission is shown when later in his letter from Ephesus, Paul refers to Apollo’s coming visit to Corinth (1 Corinthians 16:12).
Later in life, Apollo retired to the island of Crete with Zenas, where he may have been bishop. Afterward he returned to Corinth where he was bishop . Later tradition varies in that he is reported to have been bishop at a number of places including Smyrna in Asia Minor and Caesarea .
Apollo is commemorated on September 10 and March 30 . He is also remembered with Sosthenes , Cephas , Tychicus , Epaphroditus , Caesar , and Onesiphorus as part of the Seventy on December 8 , and on January 4 in the Synaxis of the Seventy Apostles.
