3 John 1:1 - Dummelow's Commentary on the Bible

1. Gaius] A Gains or Caius—the common Latin form of the name—is mentioned in four other places in the NT. (Acts 19:29; Acts 20:4; Romans 16:23; 1 Corinthians 1:14). The trait of character indicated here is in line with the generous hospitality referred to in the third of these passages. It is hardly likely, however, that one who was sufficiently prominent in the Church of Corinth to be a general host about the year 50, would be still exercising the same function some thirty years later. The identification therefore of the Gaius to whom the Third Epistle is addressed, with St. Paul's host, or with any of the others mentioned, is more than doubtful. In the truth] see on 2 John 1:1.
