Ezekiel 1:8

The four animals that bore the chariot were a type of the leading characteristics of the soul. For as the eagle rules over all the other birds and the lion is king of the wild beasts and the bull over the tamed animals and humanity …

After I wrote the letter, I remembered what is written in Ezekiel, which he showed as an example of perfection. He saw an animal above the river Chebar that had four faces and four feet and four wings. The face of the cherub is when …

After this description of the prophet, we still cannot comprehend as we read. But if we cannot comprehend the throne that he has described, how will we be able to comprehend him who sits on it, the invisible and ineffable God? It is impossible to examine closely the nature of God, but for his works, which we see, we can offer him praise and glory.

(Vers. 8, 9.) And they had four wings, and their wings were joined one to another. They did not turn back when they walked, but each one moved forward before its face. The Gospels are joined to each other and cling together, and they fly to and fro throughout the whole world, running here and there, without end to their flight, never surpassing or receding, but always proceeding to further things. And both Paul and Virgil say: Forgetting the things that are past, and reaching forth towards those things that are still to come.

"And the hand of a man under their wings on four sides." The four parts can be understood in this place as the four regions of the world, namely East, West, South, and North, because the preaching of the saints has gone forth by God's authority into all parts of the world. We can also understand by the four principal parts the four virtues from which the remaining virtues arise, namely prudence, fortitude, justice, and temperance. We truly receive these virtues when we maintain their order. For prudence is first, fortitude second, justice third, and temperance fourth. For what good can prudence do if fortitude is lacking? For to know what one cannot do is more a torment than a virtue. But he who prudently understands what he should do, and bravely does what he has understood, is without doubt already just; yet temperance ought to follow his justice, because justice very often falls into cruelty if it lacks moderation. Therefore that justice is truly justice which governs itself with the restraint of temperance, so that in the zeal with which one burns, he may also be temperate; lest if he burns too intensely, he lose the justice whose limits he does not know how to maintain. There are two lives of holy preachers, namely active and contemplative; but the active is prior in time to the contemplative, because through good work one strives toward contemplation. The contemplative, however, is greater in merit than the active, because the latter labors in the practice of present work, while the former already tastes the coming rest with an inner savor. What therefore is signified by hands if not the active life, and what by wings if not the contemplative life? The hand of a man is therefore under their wings, that is, the power of work is under the flight of contemplation. This is well represented in the Gospel by those two women, namely Martha and Mary.
