The immediate, red siren, glaring question is, 'Do these restrictions apply to ALL religions, or only to Christianity?'
Who is going to enforce it? Will he have government 'monitors' in all Churches to make sure Christians are obeying him?
On the face of it, it looks to be unenforceable. I'm not sure his personal 'edicts' have the force of actual Law.
Who is going to 'monitor' the Muslims? But of course we all know very well that when religious restrictions are applied to Christians, Muslims are always exempted by the Left.
