[RalphyS]

So much blood has been shed by the Church because of an omission from the Gospel: "Ye shall be indifferent as to what your neighbor's religion is." Not merely tolerant of it, but indifferent to it. Divinity is claimed for many religions; but no religion is great enough or divine enough to add that new law to its code.

The easy confidence with which I know another man's religion is folly teaches me to suspect that my own is also. I would not interfere with any one's religion, either to strengthen it or to weaken it. I am not able to believe one's religion can affect his hereafter one way or the other, no matter what that religion may be. But it may easily be a great comfort to him in this life--hence it is a valuable possession to him.
