St. Jude Thaddeus (1st c.) was a blood relative of Jesus Christ and one of his Twelve Apostles.
He was known for his preaching, healing, exorcisms, and his appearance was said to have closely matched that of Jesus’.
He is the patron of impossible causes, desperate situations, and hospitals.
He also wrote the book of the Bible that bears his name.
St. Simon the Zealot (1st c.) was also one of Jesus’ Twelve Apostles, but one of the most obscure.
He earned his name for being zealous for the honour of Jesus, showing a holy indignation towards those who claimed Christ with their lips while dishonouring him with their manner of life.
After the Ascension of Jesus, towards the end of his life, it is believed that St. Simon joined St. Jude to preach the Gospel in Persia, where they were both martyred in 65 A.D.
St. Simon the Zealot and St. Jude Thaddeus share a feast day on October 28th.
