Ver. 36. No man knoweth ... but the Father alone.
The words in St. Mark (xiii. 32.) are still harder: neither the angels, nor the Son, but the Father.
The Arians objected this place, to shew that Christ being ignorant of the day of judgment, could not be truly God. By the same words, no one knoweth, but the Father alone,
(as they expound them) the Holy Ghost must be excluded from being the true God. In answer to this difficulty, when it is said, but the Father alone,
it is certain that the eternal Son and the Holy Ghost could never be ignorant of the day of judgment: because, as they are one and the same God, so they must have one and the same nature, the same substance, wisdom, knowledge, and all absolute perfections. 2. It is also certain that Jesus Christ knew the day of judgment, and all things to come, by a knowledge which he could not but have, because of the union by which his human nature was united to the divine person and nature. See Colossians ii. 3. And so to attribute any ignorance to Christ, was the error of those heretics called Agnoitai.
3. But though Christ, as a man, knew the day of judgment, yet this knowledge was not due to him as he was man,
or because he was man,
but he only knew the day of judgment, because he was God as well as man. 4. It is the common answer of the fathers, that Christ here speaks to his disciples, only as he was the ambassador of his Father; and so he is only to know what he is to make known to men. He is said not to know, says St. Augustine, what he will not make others know, or what he will not reveal to them. (Witham) --- By this Jesus Christ wished to suppress the curiosity of his disciples. In the same manner after his resurrection, he answered the same question: 'Tis not for you to know the times and the moments, which the Father has placed in his own power.
This last clause is added, that the apostles might not be discouraged and think their divine Master esteemed them unworthy of knowing these things. Some Greek manuscripts add nor even the Son,
as in Mark xiii. 32. The Son is ignorant of it, not according to his divinity, nor even according to his humanity hypostatically united to his divinity, but according to his humanity, considered as separate from his divinity. (Bible de Vence)http://haydock1859.t...d.com/id42.html
