Many and well known are the proofs of her solicitude, manifested from time to time even in a miraculous manner. In the times and places in which, to the Church's grief, faith languished in lethargic indifference or was tormented by the baneful scourge of heresy, our great and gracious Lady in her kindness was ever ready with her aid and comfort.
