João 14
Gregory of Nazianzus · Comentário Patrístico (catena)
João 14:2
Are there many mansions in God's house, as you have heard, or only one? Of course you will admit that there are many, and not just one. Now, are they all to be filled, or only some, and others not, so that some will be left empty and will have been prepared to no purpose? Of course all will be filled, for nothing can be in vain that has been done by God. — AGAINST THE EUNOMIANS, THEOLOGICAL ORATION 1(27).8
João 14:16
The Spirit came after Christ so that we would not lack a Comforter. But he is called "another" Comforter so that you might acknowledge his co-equality. For this word another defines an alter ego, a name of equal lordship, not of inequality. We do not use the word another for different kinds of things but for those that are consubstantial. — ON PENTECOST, ORATION 41.12
