"...the Jews were entrusted with the oracles of God." Romans 3:2
"All Christians receive a double benefit by the apostacy and obstinacy of the Jews: one is, to know which are the true books of the Old Testament; for if all the Jews had been converted to the faith of Christ, then would the world have suspected that the Jews had invented those promises which are of Christ the Messiah: but, now, forasmuch as the Jews are enemies unto Christ, they bear witness unto us that there are no books canonical but those only which the Jews themselves acknowledged to be canonical."
-Cardinal Cajetan, source
"The papal legate, Cajetan, and Luther met face to face for the first time at Augsburg on 11 October. Cajetan (b. 1470) was "one of the most remarkable figures woven into the history of the Reformation on the Roman side . . . Surely no better qualified man could be detailed to adjust the theological difficulties."
