Christians worship God, the Creator who came in the flesh as thr Christ Jesus.
Jews are pagans pretending to be worshipping the Creator when they are rather pantheist were all of the elohims/gods are different forms of God with Satan, that is Saturn/Moloch/Baal/Remphan as their highest.
Muslims are monotheistic satan worshippers believing him to be thr Creator.
Since you mentioned Seth
hyksos indeed are a very likely fit for the Israelites. they were identified as such by flavius josephus in example and the term meaning about as much "foreign shepherds" which israel was for the most parts. Hyksos are told to have worshipped Seth as they see him closest to their own deity baal hadad (zeus basically) which i would identify as Michael and in general is the one God sends all the time. In Example when Israel is led out of Egypt by God, it is said it was an Angel of God thed led them as a pillar of smoke or light, and ultimately destroyed the egyptian forces persuing them. Usually its Michael thats send for "military operation" and defeat enemies. Now Seth is the god of foreigners, and Israel is repeatedly called foreigners in the land of egypt.
There is even an inscription that is claimed to link hyksos to the red sea crossing

As for circumcission (and extent animal sacrifices) consider all the pagan practices of human and child sacrifices and so by commanding these sacrifices in these ways he outlaws all ither forms and thus essentially a means to keep them from worse practices (which they still got attracted to)
