Rabbi Yeshua’s complete deposit of faith. “When the Spirit of truth comes, he will guide you into all the truth” Jn 16:13. Pope Paul VI, in Dei Verbum, November 18, 1965, § 8 (2) explains: “For as the centuries succeed one another, the Church constantly moves forward toward the fullness of divine truth until the words of God reach their complete fulfillment in her.”
Joseph Cardinal Ratzinger, later Pope Benedict XVI, in Dominus Iesus, August 6, 2000, § 5 (3) adds: “Thus, the Encyclical Redemptoris missio calls the Church once again to the task of announcing the Gospel as the fullness of truth: ‘In this definitive Word of his revelation, God has made himself known in the fullest possible way. He has revealed to mankind who he is.’”
The Gospels contain the fullness of truth. The Holy Spirit continues to reveal it to the Church through the development of doctrine. That continuing revelation will be complete in the superbrilliant reality of the Second Coming.
