:Christians are idolaters and Sunday is their holy day. Accordingly it is forbidden to buy and sell with them on Thursday, Friday or every Saturday within the Land of Israel. Of course Sunday itself [is forbidden to buy and sell with them], which is forbidden in every location. This is also our custom for all their holidays.<ref>Mishneh Torah, Avodah Kochavim 9:4</ref>
However Jewish Law disagrees with this opinion, as seen by the fact that Jews are not required to avoid Christians the days before and after Sunday and or other holidays, as would be required of full idolaters.
He implied it in the Laws of Kings:
:Even Jesus the Nazarene, who imagined himself as messiah, and was executed by the court -- was already prophesied about by Daniel "Those who are violent among your own people will rise up in confirmation of the vision, but they will falter." (Daniel 11:14). There was a great stumbling in this. All the prophets spoke of messiah as redeemer and saviour of the Jewish people, who will gather the exiles, and strengthen their laws. But this one has caused the destruction of Israel by the sword, the dispersal of the remnant, the exchange of the Torah for another, the misleading of most of the world to worship a g-d god other than the L-rd.<ref>Mishneh Torah, Laws of Kings and their Wars 11:4</ref>
Most of these texts are missing from the the standard Vilna edition of these works, and are assumed to have been deleted by the censors. For whatever reason, the code of Jewish Law has not made use of these supporting texts.
