St. Augustine

“Angels are spirits, but it is not because they are spirits that they are angels. They become angels when they are sent. For the name angel refers to their office, not their nature. You ask the name of this nature, it is spirit; you ask its office, it is that of an Angel, which is a messenger.”

“I should not be a Christian but for the miracles.”

“Nothing is greater than the mind of man, except God.”

“A thing is not necessarily true because badly uttered, nor false because spoken magnificently.”

“We can know what God is not, but we cannot know what God is.”

“What then is time? If no one asks me, I know what it is. If I wish to explain it to him who asks, I do not know.”

“Thou has made us for Thyself, and the heart of man is restless until it finds its rest in Thee.”
