Thomas Aquinas

“ Hence, with regard to the first mode of knowledge, the soul of Christ does not know the infinite. Because there is not an infinite number in act, even though we were to reckon all that are in act at any time whatsoever, since the state of generation and corruption will not last for ever: consequently there is a certain number not only of things lacking generation and corruption, but also of things capable of generation and corruption. ”

“ Not even in the union by personal being does the human nature comprehend the Word of God or the Divine Nature, for although it was wholly united to the human nature in the one Person of the Son, yet the whole power of the Godhead was not circumscribed by the human nature. ”

“ That which is infinite in every way can be but one. Hence the Philosopher says (De Coel. i, 2,3,) that, since bodies have dimensions in every part, there cannot be several infinite bodies. Yet if anything were infinite in one way only, nothing would hinder the existence of several such infinite things; as if we were to suppose several lines of infinite length drawn on a surface of finite breadth. ”

“ This saying of Augustine is to be understood of the grace of union, by reason of which all that is said of the Son of God in His Divine Nature is also said of the Son of Man on account of the identity of suppositum. ”
