Your "bad news" is the Donatist heresy. It was rejected by the Church -- the Catholic Church, that is -- back around the time Rome fell to the Goths.
If a priest is validly ordained and says the right words over valid Eucharistic matter and has at least the habitual intention to confect the Eucharist, he confects the Eucharist.
Why? Because the Sacrament does not depend on the righteousness of the human minister, but on the righteousness of the Savior. You are receiving, not the body of Fr. Murphy, but the Body of Christ. So it doesn't matter, from the POV of the validity of the Sacrament, whether Fr. Murphy slept with Steve, Eve, or a well-thumbed copy of the Vulgate Bible last night. Of course, as to the eternal destiny of Fr. Murphy's soul, that's an entirely different matter ...
Oh please. Read through the entire thread so you know the context and get back to me.
