Since I’m contemplating the priesthood, I’ll comment. I’ve never heard of that prayer for the Mass. It sounds like a good idea. My parish has a Vocation Cross that they give out every other Sunday Mass for the laity. It comes with a prayer card. The only thing that I dislike is when the priest says stuff like everyone is called; you have a vocation as a single life or married life, etc. Anyways, I know this is true, but it seems if you want to foster *specifically priestly *vocations, then you should pray for them specifically. But this is just my opinion. Using that prayer for the Mass sounds like an excellent idea.
