St. Jude is invoked in in desperate times, and for seemingly hopeless causes. This is due to the political climate in his day, as well as the fact that his name was often confused with Judas Iscariot, so I suppose if you had a go-to apostle, he wouldn't be the one and thus, you'd have to be pretty desperate if you were going down the ranks and calling on him! But his short chapter in the Bible packs a lot of punch.
The Epsitle of St. Jude addresses some interesting topics:
- He warns and exhorts the faithful to be wary of false prophets and their heretical teachings
- He advises that the heretics, wicked angels, and inhabitants of Sodom* will be met with terrible punishment in the end, as will those who fall away and follow them
- He encourages Christians to remain faithful to the teachings of the Apostles, even in the face of persecution from without and contentious times within Christianity
- He tells the faithful how to deal with those who have fallen away - with mercy - both by action (through aid and conversion) and in prayer (those whose obstinacy in sin is beyond the ability to help)
- His doxology is considered to be the most beautiful in the Bible:
(24) To the one who is able to keep you from stumbling and to present you unblemished and exultant, in the presence of his glory, (25) to the only God, our savior, through Jesus Christ our Lord be glory, majesty, power, and authority from ages past, now, and for ages to come. Amen.* Jude is the one who actually calls sodomy/sexual perversion a sin (verse 7), so you'll occasionally see "Jude 7" signs at anti-gay marriage/anti gay pride demonstrations.
Given the current state of things in our nation, what the polls are indicating for next week, well, could there BE a more appropriate Saint on the calendar today? Maybe it's a bit late to start a novena, but you could certainly add his novena prayer on at the end of your Rosary novena:
(Follow with an Our Father, Hail Mary, and Glory Be)
