9. What is the full and definitive stage of God's Revelation? - 65 - 66 - 73
The full and definitive stage of God’s revelation is accomplished in his Word made flesh, Jesus Christ, the mediator and fullness of Revelation. He, being the only-begotten Son of God made man, is the perfect and definitive Word of the Father. In the sending of the Son and the gift of the Spirit, Revelation is now fully complete, although the faith of the Church must gradually grasp its full significance over the course of centuries.
“In giving us his Son, his only and definitive Word, God spoke everything to us at once in this sole Word, and he has no more to say.” (Saint John of the Cross)
