Christ instituted the priesthood:
He said to them, “The kings of the Gentiles lord it over them and those in authority over them are addressed as ‘Benefactors’but among you it shall not be so. Rather, let the greatest among you be as the youngest, and the leader as the servant.For who is greater: the one seated at table or the one who serves? Is it not the one seated at table? I am among you as the one who serves.It is you who have stood by me in my trials;and I confer a kingdom on you, just as my Father has conferred one on me,that you may eat and drink at my table in my kingdom; and you will sit on thrones judging the twelve tribes of Israel.
Luke 22: 25-30
And today at the Chrism Mass, Pope Francis extols us, the lay people this way.
Dear lay faithful, be close to your priests with affection and with your prayers, that they may always be shepherds according to God’s heart.
