7.  But let no one tolerate any who say that one is the Creator of the light, and another of darkness See note 3 on Cat. iii. 33.:  for let him remember how Isaiah says, I am the God who made the light, and created darkness Is. xlv. 7.  Compare the Homily of Chrysostom on this text..  Why, O man, art thou vexed thereat?  Why art thou offended at the time that is given thee for rest Whewell, Astromomy. p. 38:  “Animals also have a period in their functions and habits; as in the habits of waking, sleeping, eating, &c., and their well-being appears to depend on the coincidence of this period with the length of the natural day.”?  A servant would have had no rest from his masters, had not the darkness necessarily brought a respite.  And often after wearying ourselves in the day, how are we refreshed in the night, and he who was yesterday worn with toils, rises vigorous in the morning because of the night’s rest Chrysostom, VI. p. 171:  “As the day brings man out to his work, so the night succeeding releases him from his countless toils and thoughts, and lulling his weary eyes to sleep, and closing their lids, prepares him to welcome the sunbeam again with his force in full vigour.”?  And what more helpful to wisdom than the night Clement of Alexandria (Stromat. IV. 22, E. Tr.):  “And in this way they seem to have called the night Euphrone, since then the soul released from the perceptions of sense turns in on itself, and has a truer hold of intelligence (φρόνησις).”?  For herein oftentimes we set before our minds the things of God; and herein we read and contemplate the Divine Oracles.  And when is our mind most attuned to Psalmody and Prayer?  Is it not at night?  And when have we often called our own sins to remembrance?  Is not at night Chrysostom (Tom. II. p. 793):  “We usually take the reckoning of our money early in the morning, but of our actions, of all that we have said and done by day, let us demand of ourselves the account after supper, and even after nightfall, as we lie upon our bed, with none to trouble, none to disturb us.  And if we see anything done amiss, let us chastise our conscience, let us rebuke our mind, let us so vehemently impugn our account, that we may no more dare to rise up and bring ourselves to the same pit of sin, being mindful of the scourging at night.”?  Let us not then admit the evil thought, that another is the maker of darkness:  for experience shews that this also is good and useful.
