CCC 715 The prophetic texts that directly concern the sending of the Holy Spirit are oracles by which God speaks to the heart of his people in the language of the promise, with the accents of "love and fidelity."5 St. Peter will proclaim their fulfillment on the morning of Pentecost.6 According to these promises, at the "end time" the Lord's Spirit will renew the hearts of men, engraving a new law in them. He will gather and reconcile the scattered and divided peoples; he will transform the first creation, and God will dwell there with men in peace.
