Pearl of Wisdom from St. Leo the Great, Pope of Rome (+461)

To seek what has already been found, to reassume what has already been achieved, to re-open discussion on what has already been defined, is not this to be ungrateful for the truth which has been acquired and to be guilty of the deadly covetousness of the forbidden fruit?

- P.L. 54, 1144 (Epistle 142, 1)
