Dominum et Vivificantem §13

¹³ It seems then that even the words spoken by Jesus in the farewell discourse should be read again in the light of that "beginning," so long ago yet fundamental, which we know from Genesis. "If I do not go away, the Counselor will not come to you; but if I go, I will send him to you." Describing his "departure" as a condition for the "coming" of the Counselor, Christ links the new beginning of God's salvific self-communication in the Holy Spirit with the mystery of the Redemption. It is a new beginning, first of all because between the first beginning and the whole of human history-from the original fall onwards-sin has intervened, sin which is in contradiction to the presence of the Spirit of God in creation, and which is above all in contradiction to God's salvific self- communication to man. St. Paul writes that, precisely because of sin, "creation...was subjected to futility..., has been groaning in travail together until now" and "waits with eager longing for the revealing of the sons of God."
