n0mesorah,
“Instead of fighting about what is proper belief like a bunch of simpletons, we would do better to discuss the benefits of an unshakable conviction in the ultimate divine powers.”
So your fight is not with me, it’s with Yaakov Avinu. When he and Lavan made a treaty, Lavan invoked the (plural) G-d of Avraham and god of Nachor, but Yaakov would only swear upon the Dread of Yitzchak. Things were tense, Lavan practically brought an army with him to assault Yaakov. Why on earth did Yaakov jeopardize this tentative peace treaty with his powerful relative by kvetching about the details of Who’s upstairs? And, surprisingly if beliefs are not so important, we learned at the seder a few weeks ago that chazal felt this simpleton belief quibble was a matter of great importance, saying that Lavan tried to destroy all of klal Yisroel with his little statement.
