"According to Ricius, world history may be divided into three stages based upon the names of God in the Bible. The first period was the natural period, where God reveals himself through the three-lettered divine name shaddai. Then there is the Torah period, where God reveals to Moses the divine name of four letters, the Tetragrammaton. In the final period of grace and redemption, God reveals the Tetragrammaton plus the letter shin, or the letter of the Logos (Christ), spelling yhswh, or the Kabbalistic name of Jesus. Thus, the name of Jesus, or the miraculous name, became the pronouncable name of the previously unpronouncable yhwh."
