extraessential

(as we said before) extraessential to religion, even by common consent; it is a great violation of love for Christians in this case to affect and desire to have those who dissent from them hardly dealt withal, and their consciences grievously imposed upon on this pretence, that they must be, in such forms and external modes of religious worship, just as themselves, or they are not to be endured.
