Even a priest in mortal sin living a leacherous life and denying the very God you claim he was ordained by is required for me to receive the bread and wine he “confects” in order to truly have a valid eucharist. His moral standing, unlike Christs, has no bearing.
Yes, there have been priests and bishops who have led infamously immoral lives. But, that doesn’t effect the sacraments. It was actually a fourth century heresy that claimed this - Donatism. The truth is that it is not the priest how bestows the grace of the sacrament, it is Jesus himself. Jesus is the principal minister of all seven sacraments, but he works through (sinful) men to do so. When the priests celebrates a sacrament, he is acting
in persona Christi - that is in the person of Christ. It is not the priest how says ‘this is my body, this is my blood’ and it is not the priest who says ‘I absolve you of your sins’, rather it is Jesus himself who says these beautiful words through his ordained ministers.
And God does use men set aside in a ministerial priesthood, and this goes all the way back through the Old Testament.
Jesus died and offered himself as the “Sinless Lamb of God”…but a sinful man who stands in his stead is still needed to obtain His grace…so now…I have “two mediators”…if I believe all grace flows thru Mary…that’s three in the line before God can be approached by me.
Yes, men are sinful. Every Catholic is a horrible sinner and so is everyone in your ecclesial community. You are a horrible sinner and I am a horrible sinner. I say to you that the Church is not a museum of saints, but a hospital for us poor sinners.
God chose to work in this world through men. God did not throw down the Scriptures as a finished good, but worked through men to write down part of his revelation (part of it remains orally transmitted, which we call Sacred Tradition). God worked through men to discern which of the myriad writings floating around should be considered canonical (hint, it turns out it is those deemed worthy to be proclaimed at Liturgy).
And yes, God worked and still works through men to confer his august grace upon us sinners. God loves his creation and uses his creation to bring us to him. God comes to us through the ordinary, through the bread and the wine that become the Eucharist, through the water that washes us of sin and bears us to a new life in him, through oil that consecrates and commissions us to preach the Gospel in all ways and to all nations.
