Not long after this marriage I was unhappily embroiled with the Duc d'Orleans, upon an occasion of no greater importance than my foot-cloth in the Church of Notre-Dame, which was by mistake removed to his seat. I complained of it to him, and he ordered it to be restored. Nevertheless the Abby de la Riviere made him believe I had put an affront upon him that was too public to be pardoned. The Duke was so simple as to believe it, and, while the courtiers turned all into banter, he swore he would receive incense before me at the said church for the future. In the meantime the Queen sent for me, and told me that the Duke was in a terrible passion, for which she was very sorry, but that nevertheless she could not help being of his opinion, and therefore insisted upon it that I ought to give him satisfaction in the Church of Notre-Dame the Sunday following. Upon the whole she referred me to Cardinal Mazarin, who declared to me at first that he was very sorry to see me in so much trouble, blamed the Abby for having incensed the Duke to such a degree, and used all the arguments he could to wheedle me to give my consent to being degraded. And when he saw I was not to be led, he endeavoured to drive me into the snare. He stormed with an air of authority, and would fain have bullied me into compliance, telling me that hitherto he had spoken as a friend, but that I had forced him henceforth to speak as a minister. He also began to threaten, and the conversation growing warm, he sought to pick a quarrel by insinuating that if I would do as Saint Ambrose did, I ought to lead a life like him. As he spoke this loud enough to be heard by some bishops at the other end of the room, I likewise raised my voice, and told him I would endeavour to make the best use of his advice, but he might assure himself I was fully resolved so to imitate Saint Ambrose in this affair that I might, through his means, obtain grace to be able to imitate him in all others.
