There is a widespread belief among many Christian denominations that Jesus and Mary are referred to in overly disrespectful,even even scatological,language language in the Talmud. Examples often given are that there is a statement that Jesus writhes eternally in excrement and that Mary was a prostitute.
I have spent many hours researching this on the internet and found sources stating this is true and sources stating it is false. I have also discovered Jewish sources defending the quotations as reactions against persecution by Christians.
I do not have the knowledge or personal resources to judge the authenticity of any of the internet sites.
