F. A. Forbes, Life of St. Vincent de Paul
“ The youngest of the family, the famous, or rather infamous, Cardinal de Retz, was not yet born, but Vincent's hands were sufficiently full without him. "I should like my children to be saints rather than great noblemen," said Madame de Gondi when she presented the boys to their tutor, but the prospect seemed remote enough. The violent temper and obstinacy of his charges were a great trial to Vincent, who used to say in later life that they had taught him, cross-grained as he was by nature, how to be gentle and patient. ”
