“I know Shadowhunters. I have for a long time. You are odd creatures. All fragile nobility and humanity on one side, and all the thoughtless fire of angels on the other. You especially, Herondale, for you have the fire of angels in your blood.”

Context: I saw an angel close by me, on my left side, in bodily form. This I am not accustomed to see, unless very rarely. Though I have visions of angels frequently, yet I see them only by an intellectual vision, such as I have spoken of before. It was our Lord's will that in this vision I should see the angel in this wise. He was not large, but small of stature, and most beautiful — his face burning, as if he were one of the highest angels, who seem to be all of fire: they must be those whom we call cherubim. Their names they never tell me; but I see very well that there is in heaven so great a difference between one angel and another, and between these and the others, that I cannot explain it.I saw in his hand a long spear of gold, and at the iron's point there seemed to be a little fire. He appeared to me to be thrusting it at times into my heart, and to pierce my very entrails; when he drew it out, he seemed to draw them out also, and to leave me all on fire with a great love of God. The pain was so great, that it made me moan; and yet so surpassing was the sweetness of this excessive pain, that I could not wish to be rid of it. The soul is satisfied now with nothing less than God. The pain is not bodily, but spiritual; though the body has its share in it, even a large one. It is a caressing of love so sweet which now takes place between the soul and God, that I pray God of His goodness to make him experience it who may think that I am lying.</p
