2 For what is there either in peace so suitable, or in a war of persecution so necessary, as to maintain the due severity of the divine rigour? Which he who resists, will of necessity wander in the unsteady course of affairs, and will be tossed here and there by the various and uncertain storms of things; and the helm of counsel being, as it were, wrenched from his hands he will drive the ship of the Church's safety among the rocks; so that it would appear that the Church's safety can be no otherwise secured, than by repelling any who set themselves against it as adverse waves, and by maintaining the ever-guarded rule of discipline itself as if it were the rudder of safety in the tempest.
Nor is it now but lately that this counsel has been considered by us, nor have these sudden appliances against the wicked but recently occurred to us; but this is read of among us as the ancient severity, the ancient faith, the ancient discipline, since the apostle would not have published such praise concerning us, when he said “that your faith is spoken of throughout the whole world” unless already from thence that vigour had borrowed the roots of faith from those times; from which praise and glory it is a very great crime to have become degenerate. For it is less disgrace never to have attained to the heraldry of praise, than to have fallen from the height of praise; it is a smaller crime not to have been honoured with a good testimony, than to have lost the honour of good testimonies; it is less discredit to have lain without the announcement of virtues, ignoble without praise, than, disinherited of the faith, to have lost our proper praises.
For those things which are proclaimed to the glory of any one, unless they are maintained by anxious and careful pains, swell up into the odium of the greatest crime.
