This is what we thought necessary to say in the present case, insofar as it concerns the pattern and example of apostolic ministry.
But if something more doctrinal must be added to what has been said, then He says that He has been sent, clearly by the Father and God.
This may be understood either in relation to the Incarnation, since He shone forth to the world with flesh by the good pleasure and approval of the Father.
Or it may be understood of Him as the Word, in some manner proceeding from the Mind that begot Him, and being sent, and fulfilling His will.
He is not to be received as the servant of another's desires. Rather, He Himself is both the living Word and the most effective will of the Father, saving those who were lost.
Therefore, after saying that the "work" belongs to Him who sent Him, He nevertheless appears Himself as the accomplisher. For all things are from the Father, through the Son, in the Spirit.
That the Son is also the Word, Counsel, Will, and Power of the Father, I think is evident to all. Yet it is not useless to bring proofs from divine Scripture.
That He is the "Word" may be seen in the words: "In the beginning was the Word, and the Word was with God, and the Word was God" (Jn 1:1).
That He is "Counsel" may be seen in the words of the Psalmist, as though addressed to God the Father: "By Thy Counsel Thou hast guided me, and with Glory Thou hast received me" (Ps 72:24).
He is also called "Will" in the words: "O Lord, by Thy Will give strength to my beauty" (Ps 29:8). For the beauty of the saints, that is, strength for every virtue, is made firm by the living and hypostatic Will of the Father, that is, the Son.
That He is also "Power" you may again understand from this: "Command, O God, by Thy Power. Strengthen, O God, this which Thou hast wrought for us" (Ps 67:29).
Here you can clearly see that by the good pleasure of God the Father, His "Power," that is, the Son, was incarnate. This was in order to "strengthen" the body "which He wrought for us."
For if He had not "dwelt among us" (Jn 1:14), the nature of the flesh would not at all have put off the weakness of corruption.
Therefore the Son Himself, being the good will of the Father, "accomplishes His work," appearing as salvation for those who believe in Him.
But perhaps someone will say to this: if the Son Himself is the will of the Father, then what will was He sent to fulfill? For what is fulfilled must be something other than the one who fulfills it.
What shall we answer to this? Indeed, the use of different names requires a distinction in the things signified. Yet in relation to God, usage often does not distinguish.
The being of the Most High Nature sometimes allows no such exactness here. For it is not spoken of as it is in all truth, but as language can express and the human ear can hear.
For he who "sees in a mirror dimly" (1 Cor 13:12) also speaks in riddles (2 Cor 12:4).
Otherwise, what will you do when the Simple One appears before us as twofold in His nature? This occurs in His words about the Israelites: "They caused their children to pass through the fire, which I did not command them, nor did it come into My heart" (Jer 32:35; 19:5).
Must there then be another heart in God? And in that case, how can He still be understood by us as simple?
Therefore, even if something about God is said in human fashion, it must be understood in a manner befitting God. The limitation of our language must not harm the Nature that is above all.
Accordingly, if the Son is found speaking of the Father's will as though of something other than Himself, do not, in sound judgment, introduce a division.
Rather, attribute to the weakness of speech its inability to say anything greater, or to express the thing signified in any other way.
I consider this also sufficient to prove that the Son is understood as the will of the Father. Yet in the saying being interpreted, no reason compels us to understand the Son by the will of the Father.
Rather, we should take it simply as the Good Counsel concerning those who were lost.
