The Disputation of Barcelona was a public debate organized by St. Raymond of Peñafort, O.P., Master of the Order of Preachers at that time. It was a debate between Judaism and Christianity held in 1263 in the royal palace of King James 1 of Aragon. The debate was between the Jєω that converted to Christianity and became a Dominican friar, Pablo Christiani, and the Kabbahlist and first zionist, Moshe ben Nahman.
Needless to say, the Kabbahlist had a very distorted perception of theology and the Messiahs. Just skimming the surface, I could notice a half a dozen errors like: the Messiahs will institute universal earthly peace, free will will no longer exist as all will be forced to comply with the law, it is better to remain faithful to the Torah, and more naturalistic errors...
If the Jєωs would have looked at this from the supernatural perspective, I believe they would see how Christianity is in concordance with the prophesies. There can be no earthly universal peace so long as you are in a battle for your soul, but the Beatific Vision does exclude sin. The followers of the Torah are completely submerged in naturalism.
I could only imagine what it would be like to be able to attend that debate.
While reading, however, I did come across one passage that seems troublesome. It was on a wikipedia page and claims the following (while siting no source, of course):
"
On the Jєωιѕн Sabbath following the close of the debate, the king, together with many preaching friars and other clergy, visited the ѕуηαgσgυє." (link-
https://en.wikipedia.org/wiki/Raymond_of_Penyafort )
The first problem I see here is that the wiki page does not state who won the debate. It is a historical fact that the Dominicans claimed victory and after this the Kabbalist was exiled from Aragon and went to the Holy Land where he died as one of the first zionist. But what is claimed by this wiki page is completely unimaginable! After a public debate organized by a great Dominican saint between a converted Jєω and a so-called Rabbi, the clergy and king went into the ѕуηαgσgυє on the Jєωιѕн sabbath??? This is the middle ages we are talking about. First, if St. Raymond of Pennafort would've authorized this, he would never have been canonized by any pope. Second, the bad impression of the clergy upon the converted Jєω would've been tremendous. After a public debate between a converted Jєω and a rabbi, the Christian clergy and king went into the ѕуηαgσgυє on the sabbath??? It sounds like public en masse apostasy. There would've been serious consequences to such an act and the Dominicans would've lost the support of the papacy and respect of the people.
