Ezekiel 1:14

But the burning coals and the lamps running among the animals are interpreted from that place of Isaiah: And the fire shall eat the flesh as the grass, and I will sanctify them in the burning fire (Isaiah 5:24). And it is written elsewhere: Burning coals shall fall upon them (Psalm 140:11). And against deceitful lips, it is said in another psalm: 'What shall be given to you, or what shall be added to you, to a deceitful tongue? Sharp arrows of the powerful, with coals of desolation.' (Psalm 119:3-4). And in another place: 'You have coals of fire, you shall sit upon them, they shall be to you for help.' (Isaiah 47:14). Whatever creature we behold, it reflects the knowledge of God, as the Creator is recognized through his creatures. And from the midst of living beings comes the splendor of fire and lightning. For if you study the Gospels, amidst the letters and humble history, you will discover the sacraments of the Holy Spirit.

There follows: And the living creatures went and returned in the likeness of flashing lightning. Since it was said above, "They did not turn back when they walked," for what reason is it now said, "The living creatures went and returned"? These statements seem very much contrary to each other, because they went and did not return, and they went and returned. But we recognize more quickly how this should be understood if we carefully distinguish the two lives, namely the active and the contemplative. For we can remain fixed in the one, but we are by no means able to hold the mind attentive in the other. For when we leave behind our sluggishness and rouse ourselves to the pursuit of good work, where else do we go but to the active life? From which we should by no means turn back afterward, because whoever returns after it to the sluggishness of negligence, to the wickednesses of depravity which he had left behind, undoubtedly does not know how to be a heavenly creature. But when we rise from the active life to the contemplative, because the mind cannot long stand in contemplation, but sees everything that it perceives of eternity through a mirror and in an enigma, as if furtively and in passing, the soul, repelled by its own weakness from the immensity of such great loftiness, slips back into itself. And it is necessary that it return to the active life and exercise itself continually in the practice of good work, so that when the mind cannot rise to contemplate heavenly things, it may not refuse to do whatever good things it can. And so it happens that, aided by its own good actions, it rises again to contemplation toward higher things and receives the nourishment of love from the pasture of contemplated truth. And because the weakness of corruption itself cannot hold itself long in this, returning again to good works, it is fed by the memory of God's sweetness, and is nourished outwardly by pious acts and inwardly by holy desires. For hence it is said of perfect men returning after their contemplation: "They shall pour forth the memory of your sweetness." For they strive always to pour forth the sweetness of intimate delight, which they can somehow touch by foretasting as if from a flash of light, by recalling and speaking of its memory. Hence the Psalmist also aptly admonishes us, saying: "Light has risen for the righteous, and gladness for the upright of…
