LOL! Boy, that answer sounds familiar. Maybe you had better look them up, as the Donatists crime was simply that they would not accept traitorous priests who had turned them in to Roman authorities during the persecution under Diocletian.
I thought this would be a waste of time. We've seen this so many times, no matter what historical record is presented it's never enough. As always I enjoy reading your thoughts roamer.
Donatists believed that in Baptism actual grace is received, it is not a useless act. They misunderstood the grace received from the sacrament comes from God and is not dependent on the faithfulness of the priest. They also believed in the Sacrifice of the Mass and the Real Presence in the Eucharist! In short, they were Catholic, except for this priest issue. St Augustine dealt with this heresy very well.
