That at the present day nothing is known concerning the union of soul and body, is proved by the hypotheses of the learned concerning the soul; especially by that of Descartes and others, [who maintain] that the soul is a substance separated from the body, in some place or other; when yet the soul is the inmost man; consequently, is the man from the head to the foot. Thence it is, according to the ancients, that the soul is in the whole, and in every part thereof; and that in whatever part the soul does not dwell inmostly, there man has no life. From this union it is, that all things of the soul belong to the body, and all things of the body belong to the soul; as the Lord said concerning His Father, that all His things are the Father's, and that all things of the Father are His (John 17:10). Thence it is that the Lord is God, even as to the flesh (Rom. 9:5; Col. 2:9); and that [He said], "the Father is in Me," and "I am in the Father" [John 14:10, 11]. Thus they are one.
