From John Locke in “A Letter Concerning Toleration” (1689):
For the Political Society is instituted for no other end but only to secure every mans Possession of the things of this life. The care of each mans Soul, and of the things of Heaven, which neither does belong to the Commonwealth, nor can be subjected to it, is left entirely to every mans self. Thus the safeguard of mens lives, and of the things that belong unto this life, is the business of the Commonwealth; and the preserving of those things unto their Owners is the Duty of the Magistrate. And therefore the Magistrate cannot take away these worldly things from this man, or party, and give them to that; nor change Propriety amongst Fellow-Subjects, (no not even by a Law) for a cause that has no relation to the end of Civil Government; I mean, for their Religion; which whether it is true or false, does not prejudice to the worldly concerns of their Fellow-Subjects, which are the things that only belong unto the care of the Commonwealth.
