But of that day and that hour knows no man, no, not the angels who are in heaven, neither the Son, but the Father.
All Commentaries on Mark 13:32 Go To Mark 13
Augustine of Hippo
AD 430
No one should arrogate to oneself the knowledge of that time by any computation of years. For if that day is to come after seven thousand years, everyone could learn its advent simply by adding up years. What comes then of the Son’s even “not knowing” this? This is said with this meaning, that his hearers do not learn this from the Son, not that he by himself does not know it. It is to be understood according to that form of speech by which “The Lord your God tries you that he may know,” which means, that he may make you know. Again, the phrase “arise, O Lord” means make us arise. Thus when the Son is said not to know this day, it is not because he is ignorant of it, but because he causes those to know it not for whom it is not yet expedient to know it, for he does not show it to them.
