In Scripture, we find a host of interrelated images and figures through which Revelation speaks of the inexhaustible mystery of the Church. the images taken from the Old Testament are variations on a profound theme: the People of God. In the New Testament, all these images find a new center because Christ has become the head of this people, which henceforth is his Body.[144] Around this center are grouped images taken "from the life of the shepherd or from cultivation of the land, from the art of building or from family life and marriage."[145]
