[I]t is impossible for those, who believe in the truth of Christianity, as a divine revelation, to doubt, that it is the especial duty of government to foster, and encourage it among all the citizens and subjects. This is a point wholly distinct from that of the right of private judgment in matters of religion, and of the freedom of public worship according to the dictates of one's conscience.
