Ezekiel 40:13

And door against door. In this place, "contra" (against/opposite) is not placed in opposition to adversity, but to rectitude. For a door is opposite a door when one arrives by a straight path from the outer entrance to the inner one. In the knowledge of almighty God, our first door is faith, while the second is the vision of Him, to which we arrive by walking through faith. For in this life we enter through the former, so that we may afterward be led to the latter. Therefore a door is opposite a door, because through the entrance of faith the entrance to the vision of God is opened. But if anyone wishes to understand both of these doors as pertaining to this life, neither does this conflict with a sound understanding. For often we wish to consider the invisible nature of almighty God, but we are by no means able to do so; and the soul, wearied by these very difficulties, returns to itself, and makes for itself steps of ascent from itself, so that it may first consider itself, if it is able, and then investigate, as far as it can, that nature which is above it. But if our mind has been scattered among carnal images, it is by no means able to consider either itself or the nature of the soul, because by however many thoughts it is led, it is blinded as if by that many obstacles. The first step, therefore, is for the soul to gather itself to itself; the second is to see what it is like when gathered; the third is to rise above itself and subject itself by directing its attention to the contemplation of the invisible Creator. But it can by no means gather itself to itself unless it has first learned to banish from the eyes of the mind the phantasms of earthly and heavenly images, to reject and trample underfoot whatever from sight, whatever from hearing, whatever from smell, whatever from touch and bodily taste presents itself to its thought, so that it may seek itself within as it is without these things. For when it thinks about these things, it turns over within itself, as it were, certain shadows of bodies. All things must therefore be driven away by the hand of discernment from the eyes of the mind, so that the soul may consider itself as it was created under God and above the body, so that, vivified by what is above, it may vivify the lower realm which it administers. The soul has been infused into the body in such a way that it is not divided into parts…

And he measured the gate from the roof of one chamber to the roof of the other, a width of twenty-five cubits. We have often said already that the gate can signify faith, and through that same faith our Lord and Redeemer himself, the Mediator of God and men, Jesus Christ, because through the faith that is in him the entrance to life lies open. But we also not undeservedly take sacred Scripture, which opens for us that same faith into the understanding of our Redeemer, as the gate, because when it is known as it ought to be, we enter into understanding invisible things. If therefore in this place, as we have said before, the gate is understood as Scripture, we must ask what is signified by the roof of the bedchamber, what by the roof of the gate. But the bedchamber has a roof, because the mind of lovers is hidden, and the fervor of love is still in secret. The gate also has a roof, because all of Scripture indeed was written for our sake, but not all of it is understood by us. For many things in it are written so openly that they feed the little ones; but certain things are veiled with more obscure meanings, so that they may exercise the strong, inasmuch as things understood with effort are more pleasing. Some things, however, are so closed in it that while we do not understand them, recognizing the weakness of our blindness, we advance more toward humility than toward understanding. For there are certain things that speak so of heavenly matters that they lie open only to those supernal citizens remaining in their homeland, and are not yet revealed to us who are pilgrims. For if someone journeying to an unknown city should hear many things about it along the way, some things indeed he gathers by reason, but other things, because he does not yet see them, he in no way knows; but the citizens themselves who are in that city both see what is left unsaid about it and understand what is said about it. We therefore are still on the way; we hear many things about that heavenly homeland; some we already understand through spirit and reason, but certain things not understood we venerate. Whence also it is written concerning that same sacred Scripture: Stretching out the heaven like a skin, who covers its upper parts in the waters. For heaven is stretched out like a skin, because through the mouths of mortals Sacred Scripture is unfolded to us in expositions. But…
