He is a saint who reminds us of what it is to be a Catholic. Orthodoxy and true belief cannot get one very far if not accompanied by love, kindness, patience, humility, and effective intervention on behalf of the poor. St. Vincent de Paul renounced his early clerical ambition in order to become a servant of the indigent. His manner was characterized by courtesy and wisdom, tempered by shrewd insight, which made his counsel sought by bishops and kings. St. Vincent was a friend of both St. Francis de Sales and King Louis XIII. The humble priest intervened in matters of great import for Church and state, as is told here:
The great political and religious conflict known as the Thirty Years War was now raging. Vincent, on hearing of the wretchedness of the people of Lorraine, collected alms for them in Paris. He sent missionaries to other countries affected by the war. Recalling his own sorrows as a slave in Tunisia, he raised enough money to ransom some twelve hundred Christian slaves in Africa. He had influence with the powerful Cardinals Richelieu and De Retz, directors of French foreign policy; and was sent for by King Louis XIII, to minister to him as he lay dying. The king's widow, Anne of Austria, now Queen Regent, had him made a member of the Council of Conscience of the five-year-old prince, the future Louis XIV. Vincent continued to be in favor at court, and during the civil war of the Fronde, tried to persuade the Queen Regent to give up her unpopular minister, Cardinal Mazarin, to help pacify and unify the people.It was St. Vincent who later appeared to St. Catherine Labouré, encouraging her to join his order. It was on his feast in 1830, formerly kept on July 19, that St. Catherine had the first of the amazing apparitions at the Rue de Bac, which were to have such immense significance to France and to the world.
