After you have reverently sanctified your eyes by gazing upon the sacred Body, receive It; but be careful lest any particle be lost. For if you lose a portion, it will be as if you lost a part of yourself; for, tell me, if someone gave you grains of gold, would you not save them with the greatest care and watch so that none would be lost and you suffer damage? Should you not, therefore, be far more careful that not even a crumb go lost of that which is more valuable than gold or precious gems?
–Saint Cyril of Alexandria (378-444)
