Eugene also shared his reaction with Hippolyte Guibert. Bearing in mind his devotion to the Catholic understanding of the Eucharistic Presence of Jesus, he wrote
I also said Holy Mass in that city of Geneva, the thoroughfare of the heresy of Calvin, where a Catholic heart finds itself so ill at ease, so oppressed by all it sees and by all it meets. My first care was to go quickly to the church to adore Jesus Christ betrayed for so long a time and blasphemed in this den of apostasy.
I confess I experienced some consolation to find him in this hostile country and it seems to me that the homage I was inspired to give him was such that particularly elevated the soul and united it sweetly to God. I celebrated on the following day the holy mysteries in these sentiments and took pleasure in recognizing our divine Master as the sovereign Lord of all men, even those who rebel against his grace; but, no matter, it would be impossible for me to live in these regions where he is so generally disregarded
Letter to Hippolyte Guibert, 29 July 1830, EO VII n 350
“It has often been said that Bishop de Mazenod was a pastor more than an intellectual. This judgment must be qualified. Many of his pastoral letters and many other letters … show that to defend the faith of the Catholics he was able to express forcefully clear and elevated principles.
Despite his profound convictions about the Catholic Church, the only one who holds the truth, and what he considers the meanderings of Protestantism, Bishop de Mazenod is sympathetic to the needs of people without dwelling on their beliefs; In this he always remains himself, a sensitive man who lives “only by the heart.”
