If a profound unity is to be found in the whole Bible, there is accordingly a beginning and an end, because the Holy Spirit desires to reveal the mystery of God to us throughout history. But who provides the end of the Scriptures? Saint John and the Johanic texts. All official Revelation concludes with the Johanic texts. Because of this, it is in the light of St John that we should read Scripture and understand the Revelation. Why did the Holy Spirit choose Saint John to give us the final secrets? Because John was the beloved disciple, but also because John was the one who received Mary into his home. This is also very important. The Word of God is a living word associated with the "good earth", with tradition and tradition began in Mary's heart. Mary is Christian tradition at its source. The one that was to give us the final passages of the mystery of God's Word had to be the same one that had intimately bonded with the mystery of the "good earth". In this way, John bonded with Christ's heart and bonded with Mary. He bonded with her at the time when they were both present and lived together the mystery of the Cross with Jesus.
