7 Such are the words and deeds by which, in our own district of the Rhone, they have deluded many women, who have their consciences seared as with a hot iron. Some of them, indeed, make a public confession of their sins; but others of them are ashamed to do this, and in a tacit kind of way, despairing of [attaining to] the life of God, have, some of them, apostatized altogether; while others hesitate between the two courses, and incur that which is implied in the proverb, “neither without nor within;” possessing this as the fruit from the seed of the children of knowledge.
