123. VIII. PIETY. It is believed by many, that spiritual life, or the life which leads to heaven, consists in piety, in external sanctity, and in the renunciation of the world; but piety without charity, and external sanctity without internal sanctity, and a renunciation of the world without a life in the world, do not constitute spiritual life; but piety from charity, external sanctity from internal sanctity, and a renunciation of the world with a life in the world, constitute it.
