I have a copy of a book "The Disputation" (1972, Scholarly Publications) which is described in its Amazon page like this:
This book is one of the finest books around to use in refuting Hebrew Christian (& Messianic) missionary claims (regular Christian claims as well). It is based upon the Medieval 12th Century debate forced upon the great Rabbinical Jewish Mystical Scholar & Poet Moses ben Nachman a/k/a Nachmanides (RAMBAN) in 1263.
Does anyone know whether this is a reliable book?
