Simon and Jude (also known as Judas or Thaddeus) are two of the lesser-known disciples, but though they are not mentioned often in the Gospel, they still are important biblical figures for their closeness to Jesus and His ministry, and for their involvement in the early Church. Their feast day is celebrated on October 28.

Both Simon and Jude are mentioned in the lists of the apostles in Luke 6:14-16 and Acts 1:12-14. We know that they accompanied Jesus on His ministry, and that they were with the rest of the apostles in Jerusalem as they chose Judas Iscariot’s successor and when the Holy Spirit descended.
