Augustine of Hippo — as excerpted in the Catena Aurea on John 14:1-4

“(Tr. lxvii. 2) And as the disciples were afraid for themselves, when Peter, the boldest and most zealous of them, had been told, The cock shall not crow, till thou hast denied Me thrice, He adds, In My Father’s house are many mansions, by way of an assurance to them in their trouble, that they might with confidence and certainty look forward, after all their trials, to dwelling together with Christ in the presence of God. For though one man is bolder, wiser, juster, holier than another, yet no one shall be removed from that house of God, but each receive a mansion suited to his deserts. The penny indeed which the householder paid to the labourers who worked in his vineyard, was the same to all; for life eternal, which this penny signifies, is of the same duration to all. But there may be many mansions, many degrees of dignity, in that life, corresponding to people’s deserts.”
