Catechism of the Catholic Church

The divine plan of Revelation is realized simultaneously "by deeds and words which are intrinsically bound up with each other" and shed light on each other. It involves a specific divine pedagogy: God communicates himself to man gradually. He prepares him to welcome by stages the supernatural Revelation that is to culminate in the person and mission of the incarnate Word, Jesus Christ. (1953,1950) > St. Irenaeus of Lyons repeatedly speaks of this divine pedagogy using the image of God and man becoming accustomed to one another: The Word of God dwelt in man and became the Son of man in order to accustom man to perceive God and to accustom God to dwell in man, according to the Father's pleasure.
