a-ka'-i-kus (Achaikos, "belonging to Achaia"):
A name honorably conferred upon L. Mummius, conqueror of Corinth and Achaia (compare CORINTH). Achaicus was one of the leaders of the Corinthian church (to be inferred from 1 Corinthians 16:15) who, visiting Paul at Ephesus with Stephanas and Fortunatus, greatly relieved the Apostle's anxiety for the Corinthian church (compare 1 Corinthians 5:1). Paul admonishes the members of the Cor church to submit to their authority (compare 1 Thessalonians 5:12) and to acknowledge their work (1 Corinthians 16:15).
