With whom is the Christian soldier meant to fight? Not with other Christians. Wretched indeed is that man’s idea of religion who fancies that it consists in perpetual controversy! He who never satisfied unless he is engaged in some strife between church and church, chapel and chapel, sect and sect, faction and faction, part and party, knows nothing yet as he ought to know… As a general rule, the cause of sin is never so much helped as when Christians waste their strength in quarreling with one another and spend their time in petty squabbles.
–Holiness, ch. 4
