Valentinus too, in a letter to certain people, writes in these very words respecting the appendages: “There is one good, by whose presence is the manifestation, which is by the Son, and by Him alone can the heart become pure, by the expulsion of every evil spirit from the heart: for the multitude of spirits dwelling in it do not suffer it to be pure; but each of them performs his own deeds, insulting it oft with unseemly lusts. And the heart seems to be treated somewhat like a caravanserai. For the latter has holes and ruts made in it, and is often filled with dung; men living filthily in it, and taking no care for the place as belonging to others. So fares it with the heart as long as there is no thought taken for it, being unclean, and the abode of many demons. But when the only good Father visits it, it is sanctified, and gleams with light. And he who possesses such a heart is so blessed, that “he shall see God.”
