Gaius
Gaius (Γάϊος, for Lat. Caius, a common Roman name), the name of three or four men in the N.T.
1. A Macedonian, and fellow-traveler of Paul, who was seized by the populace at Ephesus (Ac 19:29), A.D. 54.
2. A man of Derbe (an epithet which some have very unnaturally transferred to Timothy) who accompanied Paul in his last journey to Jerusalem (Ac 20:4), AD. 55.
3. An inhabitant of Corinth with whom Paul lodged, and in whose house the Christians were accustomed to assemble (Ro 16:23; 1Co 1:14), A.D. 55. He was perhaps the same with one of the preceding.
4. A Christian (probably of Asia Minor) to whom John addressed his third epistle (3Jo 1:1), A.D. cir. 92. SEE JOHN, EPISTLES OF. There is no good reason for regarding him as identical with either of the foregoing (Wolf, Curae, ad loc.).
