Well! Gary Macy of Santa Clara University in 1974! That settles it, a powerful argument from an unassailable authority of the type who likes to pretend the Church had no Sacraments at all until the 12th century or so.
Oh, and also Cipriano Vagaggini, who was the 1974 guy. A member of Pope Paul VI’s Theological Commission. Why, that’s practically as good as being drafted as an NFL QB in 1983 as great Commissions go! (for non Catholics, sarcasm is drifting heavily)
