Listen to his "homily" HERE.
This kind of talk is just goofy. I will give the Monsignor the benefit of the doubt and presume that his intentions are good, but really. Jesus is not a priest? Jesus was a layman?
Maybe what the Monsignor needs is a little theological updating. Perhaps he does not know that there was this little meeting of the Pope and the Bishops during the 1960's called Vatican II where the Eternal Priesthood of Jesus Christ was absolutely affirmed. Someone should suggest that the misguided reverend read Lumen Gentium and Presbyterorum Ordinis, two very important documents of Vatican II.
But perhaps, though, even before he reads those documents, he can just crack open a Bible and read the Letter to the Hebrews.
If that's too much homework, he can turn to the "Cliff Notes" version called the Catechism of the Catholic Church, where he'll find the following explanation:
"The redemptive sacrifice of Christ is unique, accomplished once for all; yet it is made present in the Eucharistic sacrifice of the Church. The same is true of the one priesthood of Christ; it is made present through the ministerial priesthood without diminishing the uniqueness of Christ's priesthood: "Only Christ is the true priest, the others being only his ministers." [paragraph 1545]
