John 8:29

And He that sent Me is with Me. He adds this (says S. Chrysostom) lest He should be accounted inferior to the Father who taught Him. The one relates to the Incarnation (dispensationem), the other to the Godhead. "The Father," says S. Augustine, "sent the Son, but did not leave Him." Moreover, the Father is ever with the Son, not only by the inseparable essence of Deity, which continues ever in number the same, but also by the special providence and guidance vouchsafed to the manhood which He assumed, the Godhead guiding and directing it in every work, to make all His work perfect and divine.
