22.  Thou hast learned, beloved, the nature of the soul, as far as there is time at present:  now do thy best to receive the doctrine of the body also.  Suffer none of those who say that this body is no work of God See iv. 18.:  for they who believe that the body is independent of God, and that the soul dwells in it as in a strange vessel, readily abuse it to fornication On the impure practices of the Manichees, see vi. 33, 34..  And yet what fault have they found in this wonderful body?  For what is lacking in comeliness?  And what in its structure is not full of skill?  Ought they not to have observed the luminous construction of the eyes?  And how the ears being set obliquely receive the sound unhindered?  And how the smell is able to distinguish scents, and to perceive exhalations?  And how the tongue ministers to two purposes, the sense of taste, and the power of speech?  How the lungs placed out of sight are unceasing in their respiration of the air?  Who imparted the incessant pulsation of the heart?  Who made the distribution into so many veins and arteries?  Who skilfully knitted together the bones with the sinews?  Who assigned a part of the food to our substance, and separated a part for decent secretion, and hid away the unseemly members in more seemly places?  Who when the human race must have died out, rendered it by a simple intercourse perpetual?
