We have a priesthood because it was founded by Christ for our well-being. It is handed on to us the same way the Scriptures were handed on to us, at the same time, and by the same people.
That is enough for me.
“That is enough for me.”
That is the point. If the Church took Christ seriously, offending priests would be immediately removed, because Sacraments are to be respected and handled respectfully by people who do not bring disgrace to themselves and to God.
