A MAP OF LIFE to one p>erson. In Christ there are two natures to one person: and our minds used to the one-natureto-one-person state of man tend to cry out that there is a contradiction in the idea of two natures to one person. But once it has been grasped that “person” and “nature” are not identical in meaning: once it has been grasped that ^he, person acts and the nature is that principle in him which deHdes hE”sphere~or action, then we see that mysterious as Our Lord’s person and nature may be, there is no contradiction. God the Son, the Second Person of the Blessed Trinity,* assumed — took to Himself — a human nature: made it His own: not simply as something which He could use as a convenient sphere to act in, but really as His own: just as our nature is our own. In us the relation of person and nature is such that not merely do we say “ I have a human nature ” (as we might say “I have an umbrella”) but person and nature are so fused in one concrete reality that we say “I am a man.” So God the Son can say not only “ I am God with a human nature to act in ” but in the most absolute fullness of meaning He can say “I am man.” He does not simply act as man: He is man — as truly man as we. This one person has two spheres of action: Christ our Lord could act either in His nature as God or in His nature as man. Remember the principle * Something will be said of the doctrine of the Trinity in Chapter VIII.
