Schisms may come, but woe to that church through whom they come! There is no right, or duty, of schism. As unity is given to the church as a gift, so it is taken away as a judgement. But on no account can disunity be a course of action that the church may embrace in pursuit of its mission or identity. The only justified breach is the one we have taken every possible step to avert, the one that lies on the far side of every conciliar process that can be devised.
