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

Dearest sons 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 you bound in the bands of charity, for I consider that without this bond we cannot please God. This is the sweet sign by which the servants and sons of Christ are recognized. But think, my sons, that this bond must be clean, and not spotted by self-love. If thou lovest thy Creator, love and serve Him in so far as He is highest and eternal good, worthy of being loved, and not for thine own profit, for that would be a mercenary love, like a miser who loves money because of his avarice. So let your love for your neighbour be clean. Love, love one another; you are neighbours one of the other. But be on your guard, for if your love were founded in your own profit or in the private affection which you might have for one another, it would not endure, but would fail, and your soul would find itself empty. The love which is founded in God must be of such a sort that it has to love with regard to virtue, and inasmuch as the friend is a creature made in the image of God. For while delight in him whom I love, or profit from him may grow less, if one abides in God love does not fail, because one loves with regard to virtue and the honour of God, and not to one's own personality. I say that if one abides in God, even if virtue should fail in him who loves, yet love does not turn away. The love of the virtue which is not there fails to be sure; but it does not fail in so far as a man is a creature of God, His member, bound in the mystical body of the Holy Church. Nay, there grows within one a love made up of great and true compassion, and with desire he brings his friend to the birth, with tears and sighs and continual prayers in the sweet Presence of God. Now this is the affection which Christ left to His disciples, which never lessens or grows languid, and is not impatient for any injury it receives; there is no spirit of criticism in it nor displeasure, because it loves the friend, not for himself, but for God. It does not judge nor want to judge the will of men, but the will of its Creator, which seeks and wills naught but our sanctification. And it joys in what God permits, of whatsoever kind it be, since it seeks naught but the honour of its Creator and the salvation of its neighbour. Truly may we say that such men are bound in the bond of charity with the band which held God-and-Man fast and nailed on the wood of the most holy and sweet Cross.

But think, sons mine, that you would never reach this perfect union did you not hold as your object Christ crucified, and follow His footsteps. For in Him you will find this love, who has loved you by grace and not by duty. And because He loves by grace, He has never grown languid in His love, neither for our ingratitude nor ignorance nor pride nor vanity, but ever persevering, even to the shameful death of the Cross, freeing us from death and giving us life. Now so do you, my sons, learn -- learn from Him. Love, love one another, with pure and holy love, in Christ sweet Jesus. I say no more, because I hope to see you again soon, when it shall please the divine goodness. Remain in the holy and sweet grace of God. Sweet Jesus, Jesus Love.
