In the Name of Jesus Christ crucified and of sweet Mary:

Dearest father in Christ sweet Jesus: I Catherine, servant and slave of the servants of Jesus Christ, write to you in His precious Blood: with desire to see in you the light of most holy faith. This is a light which shows us the way of truth, and without it no activity, or desire, or work of ours would come to fruition, or to the end for which we began it; but everything would become imperfect—slow we should be in the love of God and of our neighbour. This is the reason: seemingly love is as great as faith, and faith is as great as love. He who loves is always faithful to him whom he loves, and faithfully serves him till death. By this I perceive that in truth I do not love God, nor the creatures through God: for if in truth I loved Him, I should be faithful in such wise that I should give myself to death a thousand times a day, were it needful and possible, for the glory and praise of His Name, and faith would not fail me, since for the love of God and of virtue and of Holy Church I should set myself to endure. So I should believe that God was my help and my defender, as He was of those glorious martyrs who went with gladness to the place of martyrdom. Were I faithful I should not fear, but I should hold for sure that the same God is for me who was for them; and His power to provide for my necessities is not weakened as to capacity, knowledge, or will. But because I do not love, I do not really trust myself to Him, but the sensuous fear in me shows me that love is lukewarm, and the light of faith is darkened by faithlessness toward my Creator, and by trusting in myself. I confess and deny not that this root of evil is not yet uprooted from my soul, and therefore those works are hindered which God wants to do or puts in my way, so that they do not reach the lucid and fruitful end for which God had them begun. Ah me, ah me, my Lord! Woe to me miserable! And shall I find myself thus every time, in every place, and in every state? Shall I always close with my faithlessness the way to Thy providence? Yes, truly, if indeed Thou by Thy mercy do not unmake me, and make me anew. Then, Lord, unmake me, and break the hardness of my heart, that I be not a tool which spoils Thy works!

And I beg you, dearest father, to pray earnestly that I and you both together may drown ourselves in the Blood of the humble Lamb, which will make us strong and faithful. We shall feel the fire of the divine charity: we shall be co-workers with His grace, and not undoers or spoilers of it. So we shall show that we are faithful to God, and trust in His help, and not in our knowledge nor in that of men.

With this same faith we shall love the creature; for as love of the neighbour proceeds from love of God, so with faith, in general and in particular; as there is a general faith corresponding to the love which we ought to feel in general to every creature, so there is a special faith belonging to those who love one another more intimately: like this, which beyond the common love has established between us two a close particular love, a love which faith manifests. So much love does it manifest that it cannot believe nor imagine that one of us wishes anything else than the other's good; and it believes earnestly, for it seeks this with great insistence in the sight of God and men, seeking ever in the other the glory of the name of God and the profit of his soul; constraining Divine Help, that as it adds burdens it may add fortitude and long perseverance. Such faith bears he who loves, and never lessens it for any reason, neither for speech of man nor illusion of the devil, nor change of place. If anyone does otherwise, it is a sign that he loves God and his neighbour imperfectly.

Apparently, as I understood by your letter, many diverse battles befell you, and troubled reflections, through the deceit of the devil and through your own sensuous passion, it seeming to you that a burden was imposed on you greater than you can bear. You did not seem to yourself strong enough for me to measure you with my measure, and on this account you were in doubt lest my affection and love to you were diminished. But you did not see aright, and it was you who showed that I had grown to love more, and you less; for with the love with which I love myself, with that I love you, in the lively faith that all which is lacking on your part, God will complete by His goodness. But this is not done yet, for you have known how to find ways to throw your load down to earth. You present us many scraps of excuses to cover up your faithless frailty, but not in such wise that I do not see it quite enough now, and good it will seem to me if it is not perceived by anyone but me. Yes, yes, I show you a love increased in me toward you, and not waning. But what shall I say? How could your ignorance give place to one of the least of those thoughts? Could you ever believe that I wished anything else than the life of your soul? Where is the faith that you always used to have and ought to have, and the certainty that you have had, that before a thing is done, it is seen and determined in the sight of God—not only this, which is so great a deed, but every least thing? Had you been faithful, you would not have gone about vacillating so, nor fallen into fear toward God and toward me; but like a faithful son, ready for obedience, you would have gone and done what you could. And if you could not have gone upright, you would have gone on all fours; if you could not have gone as a Frate, you would have gone as a pilgrim; if there is no money for us, one would have gone begging. This faithful obedience would have accomplished more in the sight of God and in the hearts of men than all human prudences. My sins have prevented me from seeing it in you.

Nevertheless I am quite sure, that although selfish passion was there, you yet had and have holy and good regard to fulfil better the will of God and that of Christ on earth, Pope Urban VI. Not that I would have had you stay, though; nay, but take to the road at once, in whatever fashion and by whatever way had been open to you. Day and night I was constrained by God concerning many other things also; which, through the carelessness of him who has to do them, but chiefly through my sins which hinder every good, are all coming to nothing. And thus, ah me! we see ourselves drowning, and offences against God increasing, with many torments; and I live in an agony of delay. May God, in His mercy, soon take me from this life of shadows!

We see in the kingdom of Naples that this last disaster is worse than the first; and so many evils are likely to happen there, that may God remedy them! But He in His pity showed the disaster, and the remedies that ought to be applied. But, as I said, the abundance of my faults hinders all good. I shall have a great deal to say to you about these matters, should I not receive the greatest grace, that of release from earth before I see you again.

Yes, as I say, I do entirely wish that you had gone. Nevertheless I hold me in peace, because I am certain that nothing happens without mystery; and also because I unburdened my conscience, doing what I could that a messenger should be sent to the King of France. May the clemency of the Holy Spirit achieve it! For we by ourselves are bad workmen.

As for going quickly to the King of Hungary, it is clear that the Holy Father would be well enough pleased, and he had planned that you should go with other companions. Now, I do not know why, he has changed his mind, and wishes you to stay where you are, and do what good you can. I beg you to be zealous about it.

Abandon yourself, and every personal pleasure and consolation; and let turfs be thrown upon those who are dead, and with the cords of humble desire and holy prayer let the hands of divine justice be bound, the devil, and fleshly appetite. We are offered dead in the garden of Holy Church, and to Christ on earth, the lord of that garden. Then let us do the works of the dead. The dead man does not see nor hear nor feel. Be strong to slay yourself with the knife of hate and love, that you may not hear the derision, the insults, the reproaches of the world, which the persecutors of Holy Church would offer you. Let not your eyes see things as impossible to do, nor the torment that may follow; but let them see with the light of faith that through Christ crucified you can do all things, and that God will not impose a greater burden than can be borne. Why, we are to rejoice in great burdens, because then God gives us the gift of fortitude. With the love of endurance, fleshly sensitiveness is lost; and thus dead, dead, we may nourish ourselves in this garden. When I see this, I shall account my soul as blessed. I tell you, sweetest father, that whether we will or no, the times to-day summon us to die. Then be no more alive! End pains in pain, and increase the joy of holy desire in the pain; that our life may pass no otherwise than in crucified desire, and that we may give our bodies willingly to be eaten by beasts; that is, for the love of virtue let us willingly fling ourselves upon the tongues and hands of bestial men, as did those others who have worked, dead, in this sweet garden, and watered it with their blood, but first with their tears and sweats. And I—(grievous my life!)—because I have not given enough water to it, was refused permission to give it my blood. I will it to be no more thus, but be our life renewed and the fire of desire increased!
