Gaius of Thessaloniki

Saint Gaius of Thessaloniki is one of the seventy apostles, venerated as a saint by the Orthodox and the Roman Catholic Churches. He was a Macedonian from Thessalonica and a disciple of the Apostle Paul, whom he accompanied on his journeys.

In the year 56, together with Paul, he was at Ephesus, where he came close to suffering harm, along with Aristarchus, another disciple of Paul, in the riot of the pagan worshippers of Artemis. Gaius is regarded as the first bishop of Thessalonica.
