"The function of the total Church lies..., as history teaches, in the idea of perseverat, to which [article 10 of Dei verbum] gives a central place: in the power of persistence, which recognizes as such the false innovation that is contrary to the faith and condemns it, while holding firmly, on the other hand, to the original truth."
Joseph Ratzinger, "The Transmission of Divine Revelation" in Commentary on the Documents of Vatican II, vol. III, ed. Herbert Vorgrimler, New York: Herder, 1969, 196.
