I believe that all Catholics ought to be praying this prayer every day. Our priests need our prayers these days more than ever.
It's the kind of prayer that in the past would have made it into the Raccolta and given some kind of indulgence. But in our day, indulgences are pretty much swept under the rug, probably in order so the Vatican can be more cozy with the Lutherans (who would view promotion of the concept of indulgence as an assault against Luther's 95 Theses).
Few things are more important to pray for.
In any event, Matthew, please consider pinning this prayer at the head of this sub-forum so it's readily available for anyone who might like to read it!!
Please print this OP out and share it with your local priest because it would be great for him to duplicate it and pass it out to his faithful. Let's all pray for our priests!
