Saint Jude, also called Thaddeus, was the apostle who asked the Lord at the Last Supper why he had manifested himself only to his apostles and not to the whole world (John 14:22)St. Jude is one of the twelve apostles. He is best known as the patron of hopeless causes, but he is also the patron of Armenia, hospitals, the Chicago Police Department, and others.
you revealed yourself to us through the preaching of your apostles Simon and Jude. By their prayers, give your Church continued growth, an increase the number of those who believe in you.
We ask this through our Lord, Jesus Christ, who lives and rains with you and the Holy Spirit, one God, forever and ever. Amen.*
