For from ignorance of the Scriptures have the countless evils of our time arisen; from this ignorance the plague of heresies has broken out among us so violently; from this ignorance so many live negligent lives. Just as men deprived of daylight would not walk straight, so those who do not look to the shining of the Holy Scriptures must needs be frequently sinning as they are walking in the worst of darkness.
–Saint John Chrysostom (347-407)
