That’s false. In Judaism, there is a requirement to belive the 13 ikarim as written by the Rambam. (You can find them online as the “13 principles of faith.”)</p>
<p>You seem to be saying that is a requirement to pray, but no requirement to believe. If you don’t believe, then what exactly are you praying to? That’s like the joke about the “siddur” issued by Mordechai Kaplan–“the prayers are addressed ‘to whom it may concern’.”</p>
<p>You’re correct. It’s “needless to say” because it is not true. It’s also among the most prejudiced, small-minded and disgusting things one Jew can say about another.</p>
