So we know that it is referencing a Christian god. You stated that in the context of the first amendment respecting meant "referencing". Regardless of why definition you twist, it is still biased against other faiths. Why does it have to reference the Christian god? Why not the Muslim god?

By putting one religion's reference on property people of any belief must use it causes conflict and sometimes even alienates some.
That's one of the reasons we have a separation between church and state.
