He does seem to have a pro-Jewish, anti-Christian bias, but in this instance I think he has some valid historical and Biblical points on his side.
Thanks,
It would be nice to be know the truth of where Mt Sinai actually is,
I haven’t read the paper referenced in the link, would be curious if he mentions Paul’s journey at all,
Elijah went there and also in Galatians Paul tells us its in Arabia,
“For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children.” Galatians 4:25
