May we not say, that true zeal is not mostly charitable, but wholly so? That is, if we take charity in St. Paul's sense, for love; the love of God and our neighbour. For it is a certain truth, (although little understood in the world), that Christian zeal is all love. It is nothing else.
John WesleyTry all things by the written word, and let all bow down before it. You are in danger of [fanaticism] every hour, if you depart ever so little from Scripture; yea, or from the plain, literal meaning of an text, taken in connection with the context.
