Clare's letter to Ermentrude of Bruges
To Ermentrude, dearest sister, Clare of Assisi, humble handmaid of Jesus Christ, greetings and peace.
I know that you, o dearest sister, have fled the filth of the world, with the help of God's grace; for which I rejoice and give thanks with you and again rejoice that you tread the paths of virtue strenuously with your daughters. Be faithful, dearest, to him to whom you are promised until death, and you will be crowned by him with the laurel of life.
This labor of ours is brief, but the reward is eternal; let the noises of the fleeting world and its shadow not confound you; let the empty specters of the deceiving world not drive you mad; shut your ears to the whispers of hell and, strong, break down its attempts [against you]; willingly bear adverse evils and let provident goods not puff you up; for the one requires faith, the other demands it; what you promised God, faithfully render, and he will repay you.
O dearest, look on heaven that invites us, and bear the cross and follow Christ who preceded us; indeed, after various and many tribulations we shall enter through him into his glory. Love with your whole heart God and Jesus, his son, crucified for our sins, and never let his memory escape your mind; make yourself mediate continually on the mysteries of the cross and the anguish of the mother standing beneath the cross.
Pray and be always vigilant. And the work that you began well, finish and the ministry you assumed, fulfil in holy poverty and sincere humility. Do not fear, daughter, God is faithful in all his words and holy in all his works, he will pour out his blessing on you and your daughters; and he will be your helper and your best consoler; he is our redeemer and our eternal reward.
Let us pray God for each other, for in bearing each other's burden of charity we shall fulfil the law of Christ.
