Origin of quote: "If you wish to speak or hear about God, renounce your own body..." I've been reading Orthodox Dogmatic Theology by Protopresbyter Michael Pomazansky and encountered this quote attributed to St. Basil the Great:


  If you wish to speak or hear about God, renounce your own body,
  renounce your bodily senses, pass over the seasons of the year, their
  orderly arrangements, the adornments of the earth; stand above the
  ether, traverse the stars, their splendor, grandeur, the profit which
  they provide for the whole world, their good order, brightness,
  arrangement, movement, and the bond or distance between them. Having
  passed through all this in your mind, go about heaven and, standing
  above it, with your thought alone, observe the beauties which are
  there: the armies of angels, which are above the heavens, the chiefs
  of the archangels, the glory of the Dominions, the presiding of the
  Thrones, the Powers, Principalities, Authorities. Having gone past all
  this and left below the whole of creation in your thoughts, raising
  your mind beyond the boundaries of it, present to your mind the
  essence of God, unmoving, unchanging, unalterable, dispassionate,
  simple, incomplex, indivisible, unapproachable light, unutterable
  power, infinite magnitude, resplendent glory, most desired goodness,
  immeasurable beauty that powerfully strikes the wounded soul, but
  cannot worthily be depicted in words.


Does anyone know where it came from?
It appears that this quote is from a Homily by St. Basil titled On Faith, specifically Fide 1, which can be found in the larger work On Christian Doctrine and Practice. 


  De fide, Mark DelCogliano writes, “is one of the classic expressions of [Basil’s] Trinitarian doctrine” (On Christian Doctrine and Practice, p. 227).
