Matthias

In the New Testament Acts of the Apostles, the author of the Gospel of Luke records that Saint Matthias was the Apostle chosen by the remaining eleven apostles to replace Judas Iscariot, following Judas's betrayal of Jesus and his suicide (Acts 1:18-26).
here is no mention of a Matthias among the lists of disciples in the three synoptic gospels. According to Acts 1, in the days following the Ascension of Jesus, Peter proposed to the assembled disciples, who numbered about one hundred and twenty, that they choose one to fill the place of the traitor Judas in the apostolate:

23.So they proposed two men: Joseph called Barsabbas (also known as Justus) and Matthias. 24.Then they prayed, "Lord, you know everyone's heart. Show us which of these two you have chosen 25.to take over this apostolic ministry, which Judas left to go where he belongs." 26.Then they cast lots, and the lot fell to Matthias; so he was added to the eleven apostles.

Eduard Zeller declared this narrative is inconsistent with the history of the Apostles' movements, in that the Apostles were in Galilee after the Crucifixion. However, the Acts of the Apostles clearly states (i.12) that they returned to Jerusalem.

No further information about Matthias is to be found in the canonical New Testament. Even his name is variable: the Syriac version of Eusebius calls him throughout not Matthias but "Tolmai", not to be confused with Bartholomew (which means Son of Tolmai) who was originally one of the twelve Apostles; Clement of Alexandria says some identified him with Zacchaeus; the Clementine Recognitions identify him with Barnabas; Hilgenfeld thinks he is the same as Nathanael in the Gospel of John.

According to Nicephorus (Historia eccl., 2, 40), Matthias first preached the Gospel in Judea, then in Ethiopia (made out to be a synonym for the geographically quite separate Colchis, now Caucasian Georgia) and was crucified in Colchis. 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.

Matthias was stoned and beheaded.
