Achaicus of Corinth was a Christian apostle from the region of Achaea. According to the New Testament, he traveled alongside Fortunatus and Stephanas to deliver correspondence between the church in Corinth and Saint Paul. While the Bible does not explicitly list the names of the Seventy Disciples, Eastern Orthodox tradition includes him among this group of early followers sent by Jesus. He is recognized as a saint within the Roman Catholic and Eastern Orthodox traditions.
Life and role
As a writer and messenger, Achaicus played a role in the early communication of the Christian community. He was part of a small group that facilitated contact between Paul and the Corinthians. It remains uncertain whether these travelers reached their destination by sailing across the Aegean Sea or by walking a long distance to Ephesus.
Veneration
He is honored as a saint in several Christian traditions. In the Eastern Orthodox Church, his feast day is celebrated on 15 June alongside Fortunatus, and he is also commemorated on 4 January during the Synaxis of the Seventy Apostles.
