Is the Shulchan Aruch not consistent with the idea taught today that you can have Secular Jews / Halachically Jewish non-believing Jews?
Seif 5 An (true) apostate*, even against one Jewish law, or if he is a Jew who worships foreign gods or who publicly desecrates the sabbath, or an apostate against all of torah apart from these two they have the status of non Jews *(Cuthean was added by the censors).*a Mumar Lehachis is someone who sins (in heresy) out of anger to G-d.
No doubt it's not saying they are permitted to not keep the Torah.
But, when it says they have the status of a non-jew, does that mean that somebody Jewish cannot marry them, it'd be like marrying out to do so?
If they were to have the status of a non-jew in some ways, and the status of a jew in other ways, then in what ways do they have the status of a Jew, and in what ways do they have the status of a non-jew(while they are an apostate and public desecrator of shabbat).
