The Novena to Saint Jude is recited by anyone who is in a place of desperation in his life, as Saint Jude is the Patron Saint of the desperate. The prayer is meant for any person experiencing a difficult problem that he cannot face or cope with on his own.
The Novena is said over the span of nine consecutive days and is usually combined with fasting, meditating and praying with a fervent heart. The intention and primary mission of the prayer is to meet a special need or resolve a specific problem. The St. Jude Novena Site explains that the series of prayers over nine days is typically recited alone in a quiet environment, using a personalized rhythm and cadence.
