But we must, by acquiring superiority in the rational part, show ourselves masters of the inferior creation in us.” For he too lays down the hypothesis of two souls in us, like the Pythagoreans, at whom we shall glance afterwards. Valentinus too, in a letter to certain people, writes in these very words respecting the appendages: “There is one good, by whose presence[227] 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 alone 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.””[228] What, then, let them tell us, is the cause of such a soul not being cared for from the beginning? Either that it is not worthy (and somehow a care for it comes to it as from repentance), or it is a saved nature, as he would have it; and this, of necessity, from the beginning, being cared for by reason of its affinity, afforded no entrance to the impure spirits, unless by being forced and found feeble. For were he to grant that on repentance it preferred what was better, he will say this unwillingly, being what the truth we hold teaches; namely, that salvation is from a change due to obedience, but not from nature. For as the exhalations which arise from the earth, and from marshes, gather into mists and cloudy masses; so the vapours of fleshly lusts bring on the soul an evil condition, scattering about the idols of pleasure before the soul. Accordingly they spread darkness over the light of intelligence, the spirit attracting the exhalations that arise from lust, and thickening the masses of the passions by persistency in pleasures. Gold is not taken from the earth in the lump, but is purified by smelting; then, when made pure, it is called gold, the earth being purified. For “Ask, and it shall be given you,”[229] it is said to those who are able of themselves to choose what is best. And how we say that the powers of the devil, and the unclean spirits, sow into the sinner’s soul, requires no more words from me, on adducing as a witness the apostolic Barnabas (and he was one of the seventy, and a fellow-worker of Paul), who speaks in these words: “Before we believed in God, the dwelling-place of our heart was unstable, truly a temple built with hands. For it was full of idolatry, and was a house of demons, through doing what was opposed to God.”[230]
