St. Francis de Sales on Purity

‘Purity is the lily among virtues – by it men approach to the Angels. There is no beauty without purity, and human purity is chastity. We speak of the chaste as honest, and of the loss of purity as dishonour; purity is an intact thing, its converse is corruption. In a word, its special glory is in the spotless whiteness of soul and body. No unlawful pleasures are compatible with chastity; the pure heart is like the mother of pearl which admits no drop of water save that which comes from Heaven, – it is closed to every attraction save such as are sanctified by holy matrimony. Close your heart to every questionable tenderness or delight, guard against all that is unprofitable though it may be lawful, and strive to avoid unduly fixing your heart even on that which in itself is right and good.’

St. Francis de Sales
