No, it would seem that what you said is very clearly a more limited form of Donatism. It is not as I said before for if you'd look up what exactly the Church says of Donatism you would realize She said nothing of the grace received from the Sacraments but talked strictly on validly. As well there are Church approved private revelations which say the same as I.
How does your reception of grace have anything to do with the priest's devotion? How if the priest is not close to Christ do you except him to bring you close to Jesus.
Is your personal prayer affected because of the unseen, unknown thoughts of the priest? Your personal prayer is yours but the holy Sacrifice of the Mass is a public prayer the official one of the Church so I fail to see how this has to do with the issue at hand.
Is Christ only 75-85% there if the priest skipped his recitation of the Hours? As I just said above that has to do with validity not efficiency of the Sacrament.
As you yourseld admitted, the Donatist heresy also involves those priests which have verged into heresy. Donatists said much more: that a faithful Catholic priest who is not in state of grace could not affect a valid Sacrament.
I've never seen the Church teach that one's priest must have Faith. Then why not go to the Orthodox who have real priests but without the Faith.
I've certainly seen St. Augustine teach AGAINST that with his firm rebukes of the Donatists. I doubt that so please show me where.
And let us not forget St. Francis, who, when asked by a brother what he would do with a priest who kept three mistresses, said, "I will go to that priest and kiss the consecrated hands which have held the Body and Blood of my Lord." This has nothing to do with the theological virtue of Faith it is only a sin against the virtue of Charity. And as well I believe St. Francis was implying that no one should ever disgrace the priesthood which is a very grave sin. I ask you why, in his Introduction to a Devout Life, does St. Francis de Sales say that you can choose your own confessor (priest) though not your own bishop?
It sounds, then, that St. Francis was unconcerned with the fornicating priest's faith, which was clearly not on par with the strength you demand of your priests. As I said above the sin had nothing to do the virtue of Faith. Did you know that it is a mortal sin to attend a Mass or receive any Sacrament from a known heretic even if he still officially be within the Church?
There is a confusion between intent and faith. The faith of the priest does not matter. As long as he INTENDS to confect a valid Sacrament, he can be, if I am not mistaken, a raving anti-Catholic who does not even believe. Intention is different from faith.
No, you have a confusion between the validity and grace of a Sacrament. As well if he were "a raving anti-Catholic" why would you even think of going to him for the Sacraments?
