16. This, finally, in very fact also we experience, that those who are baptized by urgent necessity in sickness, and obtain grace, are free from the unclean spirit wherewith they were previously moved, and live in the Church in praise and honour, and day by day make more and more advance in the increase of heavenly grace by the growth of their faith. And, on the other hand, some of those who are baptized in health, if subsequently they begin to sin, are shaken by the return of the unclean spirit, so that it is manifest that the devil is driven out in baptism by the faith of the believer, and returns if the faith afterwards shall fail. Unless, indeed, it seems just to some, that they who, outside the Church among adversaries and antichrists, are polluted with profane water, should be judged to be baptized; while they who are baptized in the Church are thought to have attained less of divine mercy and grace; and so great consideration be had for heretics, that they who come from heresy are not interrogated whether they are washed or sprinkled, whether they be clinics or peripatetics; but among us the sound truth of faith is disparaged, and in ecclesiastical baptism its majesty and sanctity suffer derogation.
