destined to become his enemy?520 God forbid that there be any truth in an opinion which threatens us with a real misery that is never to end, but is often and endlessly to be interrupted by intervals of fallacious happiness. For what happiness can be more fallacious and false than that in whose blaze of truth we yet remain ignorant that we shall be miserable, or in whose most secure citadel we yet fear that we shall be so? For if, on the one hand, we are to be ignorant of coming calamity, then our present misery is not so shortsighted, for it is assured of coming bliss. If, on the other hand, the disaster that threatens is not concealed from us in the world to come, then the time of misery which is to be at last exchanged for a state of blessedness, is spent by the soul more happily than its time of happiness, which is to end in a return to misery. And thus our expectation of unhappiness is happy, but of happiness unhappy. And therefore, as we here suffer present ills, and hereafter fear ills that are imminent, it were truer to say that we shall always be miserable, than that we can some time be happy.
But these things are declared to be false by the loud testimony of religion and truth; for religion truthfully promises a true blessedness, of which we shall be eternally assured, and which cannot be interrupted by any disaster. Let us therefore keep to the straight path, which is Christ, and, with Him as our Guide and Saviour, let us turn away in heart and mind from the unreal and futile cycles of the godless. Porphyry, Platonist though he was, abjured the opinion of his school, that in these cycles souls are ceaselessly passing away and returning, either being struck with the extravagance of the idea, or sobered by his knowledge of Christianity. As I mentioned in the tenth book,521 he preferred saying that the soul, as it had been sent into the world that it might know evil, and be purged and delivered from it, was never again exposed to such an experience after it had once returned to the Father. And if he abjured the tenets of his school, how much more ought we Christians to abominate and avoid an opinion so unfounded and hostile to our faith? But having disposed of these cycles and escaped out of them, no necessity compels us to suppose
