St John of Damascus | Nor in the case of the soul of the Lord do we speak of counsel or choice...

Nor in the case of the soul of the Lord do we speak of counsel or choice, seeing that He had no part in ignorance. For, although He was of a nature that is not cognizant of the future, yet because of His oneness in subsistence with God the Word, He had knowledge of all things, and that not by grace, but, as we have said, because He was one in subsistence.

For He Himself was both God and Man, and hence He did not possess the will that acts by opinion or disposition. While He did possess the natural and simple will which is to be observed equally in all the personalities of men, His holy soul had not opinion (or, disposition) that is to say, no inclination opposed to His divine will, nor anything else contrary to His divine will.

For opinion (or, disposition) differs as persons differ, except in the case of the holy and simple and uncompounded and indivisible Godhead. There, indeed, since the subsistences are in nowise divided or separated, neither is the object of will divided. And there, since there is but one nature, there is also but one natural will.

And again, since the subsistences are unseparated, the three subsistences have also one object of will, and one activity. In the case of men, however, seeing that their nature is one, their natural will is also one, but since their subsistences are separated and divided from each other, alike in place and time, and disposition to things, and in many other respects, for this reason their acts of will and their opinions are different.

But in the case of our Lord Jesus Christ, since He possesses different natures, His natural wills, that is, His volitional faculties belonging to Him as God and as Man are also different. But since the subsistence is one, and He Who exercises the will is one, the object of the will, that is, the gnomic will, is also one, His human will evidently following His divine will, and willing that which the divine will willed it to will.
