Saint Anselm,
Proslogium — or Discourse on the Existence of God
“ But thou art what thou art, because, whatever thou art at any time, or in any way, thou art as a whole and forever. And thou art he who thou art, properly and simply; for thou hast neither a past existence nor a future, but only a present existence; nor canst thou be conceived as at any time non-existent. But thou art life, and light, and wisdom, and blessedness, and many goods of this nature. And yet thou art only one supreme good; thou art all-sufficient to thyself, and needest none; and thou art he whom all things need for their existence and wellbeing. ”
