**I don't see the point. If she's saved, she's a priest already.**
Not so fast. Yes, by reason of our Baptism we can all spread the Word of God and bring the lost to the one, holy, Catholic and apostolic Church.
However, Catholics believe that through the Sacrament of Holy Orders where the man is specifically anointed to carry out Christ's work, is the mark of the priesthood implanted.
Other sacraments that leave their mark on our souls are Baptism and Confirmation.
Traditions are fine and well.
I'm simply going by the Bible, which I quoted.
