Are believers outsiders in America?

"We are a Christian people,
according to one another the equal right of religious freedom,
and acknowledging with reverence
the duty of obedience to the will of God."
Supreme Court of the United States
U.S. v. MACINTOSH, 283 U.S. 605 (1931)

Non nobis, Domine, non nobis,
sed nomini tuo da gloriam
super misericordia tua et veritate tua.
(Psalmus 115:1)
