Jesus in Matthew 24:36
“No one knows when that day or hour will
come —not the angels in heaven, nor the
Son, but only the father”
Shouldn’t everything that is known by the father be known by the son if they were all one God?
Is the father superior to the son?
Here are quotes from three of the doctors of the Church on this topic:
[Mark 13:32 But of that day or hour no man knoweth, neither the angels in heaven, nor the Son, but the Father.]
Now why it was that, though He knew, He did not tell His disciples plainly at that time, no one may be curious where He has been silent; for ‘Who hath known the mind of the Lord, or who hath been His counsellor?’ but why, though He knew, He said, ‘no, not the Son knows,’ this I think none of the faithful is ignorant, viz. that He made this as those other declarations as man by reason of the flesh. For this as before is not the Word’s deficiency, but of that human nature whose property it is to be ignorant. And this again will be well seen by honestly examining into the occasion, when and to whom the Saviour spoke thus. Not then when the heaven was made by Him, nor when He was with the Father Himself, the Word ‘disposing all things,’ nor before He became man did He say it, but when ‘the Word became flesh.’ On this account it is reasonable to ascribe to His manhood everything which, after He became man, He speaks humanly. For it is proper to the Word to know what was made, nor be ignorant either of the beginning or of the end of these (for the works are His), and He knows how many things He wrought, and the limit of their consistence. And knowing of each the beginning and the end, He knows surely the general and common end of all. Certainly when He says in the Gospel concerning Himself in His human character, ‘Father, the hour is come, glorify Thy Son,’ it is plain that He knows also the hour of the end of all things, as the Word, though as man He is ignorant of it, for ignorance is proper to man, and especially ignorance of these things. Moreover this is proper to the Saviour’s love of man; for since He was made man, He is not ashamed, because of the flesh which is ignorant, to say ‘I know not,’ that He may shew that knowing as God, He is but ignorant according to the flesh. And therefore He said not, ‘no, not the Son of God knows,’ lest the Godhead should seem ignorant, but simply, ‘no, not the Son,’ that the ignorance might be the Son’s as born from among men.
By saying, not the angels, He stopped their mouths, that they should not seek to learn what these angels know not; and by saying, “neither the Son,” forbids them not only to learn, but even to inquire. For in proof that therefore He said this, see after His resurrection, when He saw they were become over curious, how He stopped their mouths more decidedly. For now indeed He hath mentioned infallible signs, many and endless; but then He saith merely, “It is not for you to know times or seasons.” And then that they might not say, we are driven to perplexity, we are utterly scorned, we are not held worthy so much as of this, He says, “which the Father hath put in His own power.” And this, because He was exceedingly careful to honor them, and to conceal nothing from them. Therefore He refers it to His Father, both to make the thing awful, and to exclude that of which He had spoken from their inquiry. Since if it be not this, but He is ignorant of it, when will He know it? Will it be together with us? But who would say this? And the Father He knoweth clearly, even as clearly as He knoweth the Son; and of the day is He ignorant? Moreover, “the Spirit indeed searcheth even the deep things of God,” and doth not He know so much as the time of the judgment? But how He ought to judge He knoweth, and of the secrets of each He hath a full perception; and what is far more common than that, of this could He be ignorant? And how, if “all things were made by Him, and without Him was not even one thing made,”was He ignorant of the day? For He who made the worlds, it is quite plain that He made the times also; and if the times, even that day. How then is He ignorant of that which He made?
The advice, Brethren, which ye have just heard Scripture give, when it tells us to watch for the last day, every one should think of as concerning his own last day; lest haply when ye judge or think the last day of the world to be far distant, ye slumber with respect to your own last day. Ye have heard what Jesus said concerning the last day of this world, “That neither the Angels of heaven, nor the Son knew it, but the Father.” Where indeed there is a great difficulty, lest understanding this in a carnal way, we think that the Father knoweth anything which the Son knoweth not. For indeed when He said, “the Father knoweth it;” He said this because in the Father the Son also knoweth it. For what is there in a day which was not made by the Word, by whom the day was made? Let no one then search out for the last Day, when it is to be; but let us watch all by our good lives, lest the last day of any one of us find us unprepared, and such as any one shall depart hence on his last day, such he be found in the last day of the world. Nothing will then assist thee which thou shalt not have done here. His own works will succour, or his own works will overwhelm every one.
