My dearest sister and daughter in Christ sweet Jesus. I Catherine, servant and slave of the servants of Jesus Christ, write to thee in His precious Blood, with desire to see thee a true servant and bride of Christ crucified. Servants we ought to be, because we are bought with His blood. But I do not see that we can be of any profit to Him by our service; we ought, then, to be of profit to our neighbour, because he is the means by which we test and gain virtue. Thou knowest that every virtue receives life from love; and love is gained in love, that is, by raising the eye of our mind to behold how much we are beloved of God. Seeing ourselves loved, we cannot do otherwise than love; loving Him, we shall embrace virtue through the force of love, and shall hate vice and spurn it.

So thou seest that we conceive virtues through God, and bring them to the birth for our neighbour. Thou knowest well that for the necessity of thy neighbour thou bringest forth the child charity that is within thy soul, and patience in the wrongs which thou receivest from him. Thou givest him prayer, particularly to those who have done thee wrong. And thus we ought to do; if men are untrue to us, we ought to be true to them, and faithfully to seek their salvation; loving them of grace, and not by barter. That is, do thou beware not to love thy neighbour for thine own profit; for that would not be faithful love, and thou wouldst not respond to the love which God bears thee. For as God has loved thee of grace, so He wills that since thou canst not return this love to Him, thou return it to thy neighbour, loving him of grace and not by barter, as I said. Neither if thou art wronged, nor if thou shouldst see love toward thee, or thy joy or profit lessened, must thou lessen or stint love toward thy neighbour; but love him tenderly, bearing and enduring his faults; and beholding with great consolation and reverence the servants of God.

Beware lest thou do like mad and foolish people who want to set themselves to investigate and judge the deeds and habits of the servants of God. He who does this is entirely worthy of severe rebuke. Know that it would not be different from setting a law and rule to the Holy Spirit if we wished to make the servants of God all walk in our own way -- a thing which could never be done. Let the soul inclined to this kind of judgment think that the root of pride is not yet out, nor true charity toward the neighbour planted -- that is, the loving him by grace and not by barter. Then let us love the servants of God, and not judge them. Nay, it befits us to love in general every rational creature: those who are outside of grace we must love with grief and bitterness over their fault, because they wrong God and their own soul. Thus thou shalt be in accord with that sweet enamoured Paul, who mourns with those who mourn, and joys with those who joy; thus thou shalt mourn with those who are in mournful state, through desire for the honour of God and for their salvation; and thou shalt joy with the servants of God who rejoice, possessing God through loving tenderness.

Thou seest, then, that through charity to God we conceive virtues, and through charity toward our neighbours they are brought to the birth. Being thus -- loving thy neighbour sincerely, without any falsity of love or heart, freely, without any regard to thine own profit, spiritual or temporal -- thou shalt be a true servant, and respond by means of thy neighbour to the love which thy Creator bears thee; thou shalt be a faithful, not a faithless bride. Then does the bride fail in faith to her bridegroom, when she gives to another creature the faith which she ought to give to him. Thou art a bride, for Christ in His circumcision showed that He would wed the human race. Thou, beholding love so ineffable, shouldst love Him without any means that might be apart from God. Thus art thou made the servant of thy neighbour, serving him in all things to the measure of thy power. Verily thou art the bride of Christ, and shouldst be the servant of thy neighbour. If thou art a faithful bride, since we can neither be of profit nor of service to God by the love which we bear Him, we ought, as I said, to serve our neighbour with true and heartfelt love. In no other way nor wise can we serve Him. Therefore I said to thee that I desired to see thee the true servant and bride of Christ crucified. I say no more. Remain in the holy and sweet grace of God. Sweet Jesus, Jesus Love.
