Well then again, what sect of Christianity were we when we were a Christian nation?
Founding Father Benjamin Rush said the following...
"Such is my veneration for every religion that reveals the attributes of the Deity, or a future state of rewards and punishments, that I had rather see the opinions of Confucius or Mahomed inculcated upon our youth, than see them grow up wholly devoid of a system of religious principles. But the religion I mean to recommend in this place, is that of the New Testament."
No need for sects... no need for devoidness either.
