Isaias 50:11

This “wood,” again, Isaac the son of Abraham personally carried for his own sacrifice, when God had enjoined that he should be made a victim to Himself. But, because these had been mysteries which were being kept for perfect fulfilment in the times of Christ, Isaac, on the one hand, with his “wood,” was reserved, the ram being of fered which was caught by the horns in the bramble; Christ, on the other hand, in His times, carried His “wood” on His own shoulders, adhering to the horns of the cross, with a thorny crown encircling His head. …

Now, since you join the Jews in denying that their Christ has come, recollect also what is that end which they were predicted as about to bring on themselves after the time of Christ, for the impiety wherewith they both rejected and slew Him. For it began to come to pass from that day, when, according to Isaiah, “a man threw away his idols of gold and of silver, which they made into useless and hurtful objects of worship;” in other words, from the time when he threw away his idols after the truth had been made clear by Christ. Consider whether what follows in the prophet has not received its fulfilment: “The Lord of hosts hath taken away from Judah and from Jerusalem, amongst other things, both the prophet and the wise artificer;” that is, His Holy Spirit, who builds the church, which is indeed the temple, and household and city of God. …

4. We find in the prophet Isaiah, that the fire with which each one is punished is described as his own; for he says, “Walk in the light of your own fire, and in the flame which ye have kindled.” By these words it seems to be indicated that every sinner kindles for himself the flame of his own fire, and is not plunged into some fire which has been already kindled by another, or was in existence before himself. Of this fire the fuel and food are our sins, which are called by the Apostle Paul “wood, and hay, and stubble.” And I think that, as abundance of food, and provisions of a contrary kind and amount, breed fevers in the body, and fevers, too, of different sorts and duration, according to the proportion in which the collected poison supplies material and fuel for disease (the quality of this material, gathered together from different poisons, proving the causes either of a more acute …

XXXVI. I will remind you again about Illuminations, and that often, and will reckon them up from Holy Scripture. For I myself shall be happier for remembering them (for what is sweeter than light to those who have tasted light?) and I will dazzle you with my words. There is sprung up a light for the righteous, and its partner joyful gladness. And, The light of the righteous is everlasting; and Thou art shining wondrously from the everlasting mountains, is said to God, I think of the Angelic powers which aid our efforts after good. And you have heard David’s words; The Lord is my Light and my Salvation, whom then shall I fear? And now he asks that the Light and the Truth may be sent forth for him, now giving thanks that he has a share in it, in that the Light of God is marked upon him; that is, that the signs of the illumination given are impressed upon him and recognized. …

75. Let us also pass over this fire of lust, fearing which Paul, but fearing for us, inasmuch as by buffeting his body he had come no longer to fear for himself, says to us: “Flee fornication.” Let us then flee it as though following us, though indeed it follows not behind us, but within our very selves. Let us then diligently take heed lest while we are fleeing from it we carry it with ourselves. For we wish for the most part to flee, but if we do not wholly cast it out of our mind, we rather take it up than forsake it. Let us then spring over it, lest it be said to us: “Walk ye in the flame of your fire, which ye have kindled for yourselves.” For as he who “takes fire into his bosom burns his clothes,” so he who walks upon fiery coals must of necessity burn his feet, as it is written: “Can one walk upon coals of fire and not burn his feet?”

I should say then that the saints who keep a firm hold of the recollection of God and are borne along, as it were, with their steps suspended on a line stretched out on high, may be rightly compared to rope dancers, commonly called funambuli, who risk all their safety and life on the path of that very narrow rope, with no doubt that they will immediately meet with a most dreadful death if their foot swerves or trips in the very slightest degree, or goes over the line of the course in which alone is safety. …

But the fact that to us on the contrary the yoke of Christ seems neither light nor easy, must be rightly ascribed to our perverseness, as we are cast down by unbelief and want of faith, and fight with foolish obstinacy against His command, or rather advice, who says: “If thou wilt be perfect, go sell (or get rid of) all that thou hast, and come follow Me,” for we keep the substance of our worldly goods. And as the devil holds our soul fast in the toils of these, what remains but that, when he wants to sever us from spiritual delights, he should vex us by diminishing these and depriving us of them, contriving by his crafty wiles that when the sweetness of His yoke and lightness of His burden have become grievous to us through the evil of a corrupt desire, and when we are caught in the chains of that very property and substance, which we kept for our comfort and solace, he may always torme …
