This is an excellent video on the priesthood put out by the Congregation for the Clergy from the Vatican. There is lots of talk about the Cure of Ars. The Pope also speaks on this video. I am sure you will learn a lot about what it means to be a priest. I found it beautiful and a real encouragement for the living out of my priesthood. Also, this may be the best vocation video for the priesthood it have seen.
There are two other videos that are part of the series. I will post them on a later date.
