Please be guided by the verses from the book of Hebrews:
Hebrews 7:17
For it is declared:
“You are a priest forever in the order of Melchizedek.”
23-27
Now there have been many of those priest, since death prevented them from continuing in office; but because lives forever, he has a permanent priesthood. Therefore he is able to serve completely those who come to God through him, because he always lives to intercede for them. Such a high priest meets our need—one who is holy, blameless, pure, set apart from sinners, exalted above the heavens. Unlike the other high priests, he does not need to offer sacrifices day after day, first for his own sins, and then for the sins of the people. He sacrificed for their sins once for all when he offered himself.
The Catholic Church is short of priests, so it is so sad to hear of priest killed like what happened in Mexico, a priest already in in his 84 was bound and killed
