“God gives His communion to all who love Him. Communion with God is life and light and sweetness with all the good things that He has. But those who of their own will forsake him he rewards with separation from Him, which they themselves have chosen. As separation from light is darkness, so also alienation from God is deprivation of all good things which He has.”

(St. Irenaeus of Lyons ‘Against Heresies’)
