Today the church commemorates St. Simon and St. Jude. From the Treasury of Daily Prayer:
In the lists of the twelve apostles (Matthew 10:2-4; Mark 3:16-19; Luke 6:14-16; Acts 1:13), the tenth and eleventh places are occupied by Simon the Zealot (or "Cananaean") and by Jude (or "Judas," not Iscariot bot "of James"), who was apparently known also as Thaddaeus. According to early Christian tradition, Simon and Jude journeyed together as missionaries to Persia, where they were martyred. It is likely for this reason, at least in part, that these two apostles are commemorated on the same day. Simon is not mentioned in the New Testament apart from the lists of the twelve apostles. Thus he is remembered and honored for the sake of his office, and thereby stands before us--in eternity, as in his life an ministry on earth--in the name and stead of Christ Jesus, our Lord. We give thanks to God for calling and sending Simon, along with Jude and all of the apostles, to preach and teach the Holy Gospel, to proclaim repentance and forgiveness, and to baptize in the name of the Father and of the Son and of the Holy Spirit (John 4:1-2; Matthew 10; 28:16-20; Luke 24:46-49).
And so we pray:
Almighty God, You chose Your servants Simon and Jude to be numbered among the glorious company of the apostles. As they were faithful and zealous in their mission, so may we with ardent devotion make known the love and mercy of our Lord and Savior Jesus Christ, who lives and reigns with You and the Holy Spirit, one God, now and forever. Amen.
