Wrong. This is heresy. If the priest has expressed the intention to "Do what the Church does" and never retracted it, his internal disposition is incidental. Sinner, apostate, heretic..his words of consecration confect the sacrament. It is Christ who acts, not the priest.
You need to learn some elementary sacramental theology, thorski. Your ignorance is showing.
Let's say there's a priest who no longer believes the doctrines of the Church, specifically regarding transubstantiation. He has no intention of consecrating the Eucharist because he doesn't believe it is possible, or real. Isn't that a "retraction" even if he doesn't formally announce it?
Now let's suppose, not that this could ever happen /sarcasm, this priest becomes an active agent for satan, wouldn't he be more effective as such if everyone in his parish etc. was unaware that he secretly retracted his intention?
