Matthias was one of the seventy disciples of Jesus, and had been with Him from His baptism by John to the Ascension (Acts i, 21, 22). It is related (Acts, i, 15-26) that in the days following the Ascension, Peter proposed to the assembled brethren, who numbered one hundred and twenty, that they choose one to fill the place of the traitor Judas in the Apostolate. Two disciples, Joseph, called Barsabas, and Matthias were selected, and lots were drawn, with the result in favour of Matthias, who thus became associated with the eleven Apostles.
