Saint Matthias Saint Matthias Matthias (Hebrew transliteration: "Mattityahu"; Koine Greek: Μαθθίας; ; died c. 80 AD) was, according to the Acts of the Apostles, the apostle chosen to replace Judas Iscariot following Judas' betrayal of Jesus and his (Judas') subsequent death. His calling as an apostle is unique, in that his appointment was not made personally by Jesus, who had already ascended into heaven, and it was also made before the descent of the Holy Spirit upon the early Church. There is no mention of a Matthias among the lists of disciples or followers of Jesus in the three synoptic gospels, but
Jude the Apostle in his place. This has led many Christians since early times to harmonize the lists by positing a "Jude Thaddeus", known by either name. This is made plausible by the fact that "Thaddeus" seems to be a nickname (see Thaddeus) and that many New Testament figures have multiple names (such as Simon Peter and Joseph Barnabas). A further complication is the fact that the name "Judas" was tarnished by Judas Iscariot. It has been argued that for this reason it is unsurprising that Mark and Matthew refer to him by an alternate name. Some Biblical scholars reject this theory, however,
