Chapter 42 — That the Catholic faith teaches this

Hence we are instructed in the rule of Catholic faith to profess that the Son is consubstantial with the Father, a phrase that excludes two things. First, the Father and the Son may not be thought of according to bodily generation, which is effected by a separation of the son’s substance from the father, such that the Son could not be consubstantial with the Father. Second, so that we do not think of the Father and the Son according to intellectual generation in the way that a word is conceived in our mind: as a thing coming to the intellect as an accident and not existing from its essence.
