SOULS begin to enter the dark night when God is drawing them out of the state of beginners, which is that of those who meditate on the spiritual road, and is leading them into that of proficients, the state of contemplatives, that, having passed through it, they may arrive at the state of the perfect, which is that of the divine union with God. That we may the better understand and explain the nature of this night through which the soul has to pass, and why God leads men into it, it may be well to touch first upon certain peculiarities of beginners, which, though treated in the briefest possible way, it is well for them to know, that they may perceive the weakness of the state they are in, take courage, and desire to be led of God into this night, where the soul is established in virtue and made strong for the inestimable delights of His love. Though I shall dwell at some length upon this point, I shall do so no longer than suffices for the immediate discussion of this dark night.
We are to keep in mind that a soul, when seriously converted to the service of God, is, in general, spiritually nursed and caressed, as an infant by its loving mother, who warms it in her bosom, nourishes it with her own sweet milk, feeds it with tender and delicate food, carries it in her arms, and fondles it. But as the child grows up the mother withholds her caresses, hides her breasts, and anoints them with the juice of bitter aloes; she carries the infant in her arms no longer, but makes it walk on the ground, so that, losing the habits of an infant, it may apply itself to greater and more substantial pursuits.
The grace of God like a loving mother, as soon as the soul is regenerated in the new fire and fervor of His service, treats it in the same way; for it enables it, without labor on its own part, to find its spiritual milk, sweet and delicious, in all the things of God, and in devotional exercises great sweetness; God giving it the breasts of His own tender love, as to a tender babe. Such souls, therefore, delight to spend many hours, and perhaps whole nights, in prayer; their pleasures are penances, their joy is fasting, and their consolations lie in the use of the sacraments and in speaking of divine things.
Now spiritual men generally, speaking spiritually, are extremely weak and imperfect here, though they apply themselves to devotion, and practice it with great resolution, earnestness, and care. For being drawn to these things and to their spiritual exercises by the comfort and satisfaction they find therein, and not yet confirmed in virtue by the struggle it demands, they fall into many errors and imperfections in their spiritual life; for every man’s work corresponds to the habit of perfection which he has acquired. These souls, therefore, not having had time to acquire those habits of vigor, must, of necessity, perform their acts, like children, weakly.
To make this more clear, and to show how weak are beginners in virtue in those good works which they perform with so much ease and pleasure, I proceed to explain by reference to the seven capital sins, pointing out some of the imperfections into which beginners fall in the matter of each of them. This will show us plainly how like children they are in all they do, and also how great are the blessings of this dark night of which I am about to speak; seeing that it cleanses and purifies the soul from all these imperfections.
