I dont know what I can replace it with

Deism! We have cookies 😄 & almost no "rules" at all.

It's really a philosophy but it used to be very popular. Many of the Founding Fathers were Deists as well as being Christians.

Essentially: Deists believe in God, just one, who created the Universe on purpose & with a plan. He probably doesn't interfere much since the Big Bang or whatever mechanism He used. Freewill is essential, ofc.
