All information concerning the ministry and death of Matthias is vague and contradictory. The tradition of the Greeks says that St. Matthias spread Christianity around
Cappadocia and on the coasts of the
Caspian Sea, residing chiefly near the port
Hyssus. According to
Nicephorus (
Historia eccl., 2, 40), Matthias first preached the Gospel in
Judaea, then in Aethiopia (by the region of
Colchis, now in modern-day
Georgia) and
was crucified. A marker placed in the ruins of the Roman fortress at
Gonio (Apsaros) in the modern Georgian region of
Adjara claims that Matthias is buried at that site. The
Synopsis of Dorotheus contains this tradition: "Matthias preached the Gospel to barbarians and meat-eaters in the interior of Ethiopia, where the sea harbor of Hyssus is, at the mouth of the river
Phasis. He died at
Sebastopolis, and was buried there, near the Temple of the Sun." According to
Hippolytus of Rome, Matthias died of old age in Jerusalem.
Clement of Alexandria observed (
Stromateis vi.13.): Not that they became apostles through being chosen for some distinguished peculiarity of nature, since also Judas was chosen along with them. But they were capable of becoming apostles on being chosen by Him who foresees even ultimate issues. Matthias, accordingly, who was not chosen along with them, on showing himself worthy of becoming an apostle, is substituted for Judas. ==Writings==
