A quote from the Fathers is historical evidence of what the early Church believed.

I hope you don't mind me jumping in, but do you quote any of the Donatist's as well? I think their view of historical events and their causes might differ.

Since they were heretical, naturally I wouldn't quote them as expressing a belief of the Church, but quoting, for example St. Augustine debating them would indeed explain their heresy and the view taken by the Church.
