To me, this grace was given me to preach to the Gentiles the inscrutable riches of Christ so that the manifold wisdom of God might be made known. The Church honors today the life and vocation of St. Francis de Sales. Born in Thorens, Savoy, France, St. Francis was bishop of Geneva where he vigorously fought Calvinism. He sought to bring many back to the Church through his personal life and writings. Together with St. Jane Frances de Chantal, he founded the Order of the Visitation. He was canonized in 1665 and was proclaimed Doctor of the Church in 1877. He is the patron of writers, journalists, and the deaf. 
In the First Reading, St. Paul is letting the Ephesians know that his own unmerited call to preach to, and boldly evangelize the Gentiles, is a highpoint in a much larger mysterious plan of God. This plan is the coming to knowledge of God by the Gentiles. Whereas St. Francis de Sales cannot claim to be St. Paul by any means, he too was able to play a part in the continued unveiling of God’s plan to the nations. He accomplished this both as a preacher and a bishop. His dedication as a preacher led to conversion to faith of many souls. As a bishop, St. Francis understood that it was his responsibility not only to preach the Word but also to ensure that he shepherded to eternal life the flock which the Lord had put under his charge. Like the good shepherd about whom we have read in the Gospel passage, the wellbeing of the flock was Francis’ priority. It was for this reason that he fiercely fought Calvinism which was leading many people to stray from the one true faith. 
Whereas all of us cannot become bishops or great doctors of the Church, as the baptized, we are called to be preachers of the Good News. Like St. Francis de Sales, we too have been given the commission to win over souls for the Lord. Through the intercession of St. Francis, may we remain zealous in teaching the true doctrine of our Lord Jesus Christ. May we be able to find our own “Calvinists” and help them find their way to God.
