"Philosophize about the world or worlds; about matter; about soul; about natures endowed with reason, good or bad; about resurrection, about judgment, about reward, or the Sufferings of Christ. For in these subjects to hit the mark is not useless, and to miss it is not dangerous."

“He will come again with His glorious Presence to judge the quick and the dead; no longer flesh, nor yet without a body, according to the laws which He alone knows of a more godlike body.”

“The Judgment and the Reward according to the righteous scales of God... will be Light to those whose mind is purified proportionate to their degree of purity, which we call the Kingdom of heaven; but to those who suffer from blindness of their ruling faculty, darkness, that is estrangement from God, proportionate to their blindness here.”

“For my sake He was called a curse, who destroyed my curse ; and sin, who taketh away the sin of the world ... Of the same kind, it appears to me, is the expression, ‘My God, My God, why hast Thou forsaken Me?’ It was not He who was forsaken either by the Father, or by His own Godhead... He was in His own Person representing us. For we were the forsaken and despised before, but now by the Sufferings of Him Who could not suffer, we were taken up and saved.”

“I offer this gift to my God, I dedicate this gift to Him. Only this remains to me as my treasure. I gave up everything else at the command of the Spirit. I gave all that I had to obtain the pearl of great price. Only in words do I master it, as a servant of the Word. I would never intentionally wish to disdain this wealth. I esteem it, I set value by it, I am comforted by it more than others are comforted by all the treasures of the world. It is the companion of all my life, a good counselor and converser; a guide on the way to Heaven and a fervent co-ascetic.”

“I know of three classes among the saved; the slaves, the hired servants, the sons. If you are a slave, be afraid of the whip; if you are a hired servant, look only to receive your hire; if you are more than this, a son, revere Him as a Father, and work that which is good, because it is good to obey a Father; and even though no reward should come of it for you, this is itself a reward, that you please your Father.”
