I wouldn't be so quick to attach "beneficent'' to Christianity. From the conquests and horrors of the Conquistadors to the modern catholic church operating a child sex abuse syndicate, the human suffering inflicted on humanity by Christianity is horrendous.
The library of congress (link below), has an enormous catalog of early American history. It’s also important to remember that the framers of the Constitution were aware the early colonies of settlers were conclaves of religious intolerance, wherein a Baptist in one colony was safe, but a Roman Catholic was a criminal, yet in a different colony the reverse was true. This is completely unworkable and the Founding Fathers knew it.
The various sects of Christianity were completely at odds with one another as colonial states. Catholics couldn't live in one state, Quakers were executed if they went to another, Protestants were reviled in still others, and so on. These documents still exist. Anyone can research the laws of the original 13 colonies.
Puritans expelled dissenters from their colonies, including Roger Williams and Anne Hutchinson. Although they were victims of religious persecution in Europe, the Puritans supported the theory that sanctioned it, the need for uniformity of religion in the state.
