He was wrong as there is no context to arrive at that conclusion and it mentions the Jews, Christians and Sabeans later in another book which killed his premise for context. There was also another where he was questioning the HB but he embarrassed himself with his biased interpretation of the word begotten.Not sure if it's the same one that I've seen but in the one I saw it was clear what he was saying
It referred to past and present as in those who were Christians and Jews before the current revelations came were saved
So for the Jews before christianity or for the Christians before Islam there is no fear
once the new religion has been established those following the older one would not be exempt and will be lost
