One of the most interesting spiritual "evidences" that Augustine's position was absolutely correct is that the RCC pretends that Augustine never said this.
PINOs need to think about that.
Respectfully, I don't know that this point constitutes "evidence" to PINO ears. It surely should, but I am nearly sure that it don't.
To the PINO's, modern semi-pelagian Roman Catholic disavowal of Augustine is a Noble Good. PINO's hate Augustine; in their view, the only thing Rome really got "wrong" was that whole Papal Supremacy thing.
Of course, if the "true gospel" (Conditional Self-Election) never left Rome, then who are THEY to doubt Mother Rome's authority? If Rome has preserved the True Gospel, then Rome is the Ark of the Covenant, and her Authority is not to be questioned.
And even if Papal Supremacy is "wrong", but Rome's Gospel is "right"... then it is an abiding mystery to me as to why these PINO schismatics do not become conditional self-electionist Greek Orthodox.
