St. Jude

St. Jude is a popular saint, but not much is known about his life. He was sometimes called Judas (not to be confused with Judas Iscariot), Jude Thaddaeus, or Thaddaeus. Possibly due to a scribal error, Thaddaeus is sometimes mistakenly called Labbaeus.
St. Jude was one of Jesus' twelve apostles, as mentioned in Luke 6:16 and Acts 1:13. Mark 3:18 and Matthew 10:3 refer to him as Thaddeus and he is believed to be the author of the Epistle of Jude. Thaddeus is also identified traditionally with the Judas referred to in John 14:22 and is believed to be one of the brothers of Jesus mentioned in Mark 6:3 and elsewhere.
Among Roman Catholics, St. Jude is known as the patron saint of desperate causes. He is believed to be able to intervene in such cases and create miraculous solutions. Novenas (prayer services) are often dedicated and/or directed to St. Jude.

The following is a popular prayer to St. Jude:

May the Sacred Heart of Jesus
Christ be adored, glorified, loved,
and perserved throughout the world,
now and forever. Sacred Heart of Jesus,
pray for us. St. Jude, helper of the helpless,
pray for us. St. Jude, worker of miracles,
pray for us.

Repeat this prayer as you would with any affirmation, that is, at least six times in a row, several times during the day, and especially during your personal prayer or meditation times.
