This book is triggered by a statement made by Gershom Scholem in his article on Abraham Ben Samuel Abulafia, transmitter of the kabbalah of the prophets. He states regarding Abulafia's prophetic revelations "The unintentional similarities of his "prophetic revelations" with Christian doctrine confused his pupils to such a degree that some accepted baptism". The Sefer Ha Ot, or Book of the Sign or Letter is Abulafia's sole remaining book of prophecy. The study looks at elements of this book and Abulafia's Kabbalistic method that might have lead to his disciples turning to Jesus of Nazareth, and perhaps to Abulafia being driven to an island populated by rabbits by the famous Rabbinic kabbalistic authority Rashba and his herem. How was Abulafia's teaching able to produce baptized saints in Christ Jesus?
