Yes, administrative mistakes versus teaching mistakes.
The Catholic Church is full of sinners and hypocrites. But the Church does not err when it makes a declaration ex-Cathedra or when the Pope says something in conjunction with the Bishops (e.g. a global Council of the Bishops).
Point out that there are sinners in the Church is sort of like saying that the sky is dark at night.
i think some of these guys think church folk are supposed to be perfect
