“The examples of these Eastern and Western monks suggest that the intellectual and theological obedience or self-restraint required to be orthodox is more than superficially analogous to the psychological and moral obedience or self-restraint required to be ascetic. . . . A passionate zeal for orthodoxy has historically become a special cause for those who have consecrated their lives to poverty, chastity and obedience.”
-Pelikan, Credo. 299-300.
