Some Jews say:
Why do I need to worry about all these commandments? I’ll just be a good person and not bother others. I don’t steal, kill, or commit adultery. Really, that’s what matters in the grand scheme of things.
Other Jews say:
The important thing, what makes us Jewish, is our relationship with God. Prayer, kosher, Shabbat – these are the central Jewish tenets and hallmarks of religiosity.
You’re both half-right, and you’re both wrong. You’re both incomplete. And you’re each only tapping into half-Judaism.
