For those who assume that God wouldn’t let a movement he disapproves of succeed, Psalm 50 is worth a read.
What right have you to recite my laws
or take my covenant on your lips?
You hate my instruction
and cast my words behind you.
When you see a thief, you join with him;
you throw in your lot with adulterers.
You use your mouth for evil
and harness your tongue to deceit.
You speak continually against your brother
and slander your own mother’s son.
These things you have done and I kept silent;
you thought I was altogether like you.
Read the Psalmist for the rest of the story.
Existence does not excuse discernment.
