“…it is not authority that is bad, but the love of authority; not glory, but the love of glory and – what is worse – vainglory; not the acquisition of virtue, but to suppose that one has acquired it; not spiritual knowledge, but to think that one is wise and – worse than this – to be ignorant of one’s own ignorance; not true knowledge but what is falsely called knowledge (cf. I Tim. 6:20); not the world, but the passions; not nature, but what is contrary to nature; not agreement, but agreement to do what is evil and does not contribute to the soul’s salvation; not the body’s members, but their misuse.”

~St. Peter of Damaskos.
