No one is safe, because his brother is in danger: no man is better, because his neighbour is worse. Our warfare is not with men, but with sins. We love the erring, but not their errors; and we oppose their errors, because we love the erring, and because we desire their salvation, which is perilled by their errors, and because we love the truth, which is able to save their souls.
We know that Error is manifold, but Truth is one: and that, therefore, it is not enough to oppose Error: for one error may be opposed by another error; and the only right opposition to Error is Truth. We know, also , that by God’s mercy there are truths in the Church of Rome as well as errors; and that some who oppose Rome, may be opposing her truths, and not her errors. But our warfare is against the errors of Rome, and for the maintenance of the truth of Christ. We reject Popery because we profess Christianity. We flee Babylon, because we love Zion. And the aim of our warfare is not to destroy our adversaries, but to save their souls and ours. Therefore in what we have said on this subject, we have endeavoured to follow the precept of the Apostle, Speak the truth in love (Eph. Iv.15); and if, through human infirmity, any thing has been spoken otherwise, we pray God that it may perish speedily, as though it had never been.
