Pope Leo XIV
Habemus Papam!
It's with great joy that we welcome our Holy Father, Pope Leo XIV , elected on May 8th, feast day of our blessed Marie-Catherine of Saint-Augustin!
''Peace be with you all!
Dear brothers and sisters, these are the first words spoken by the risen Christ, the Good Shepherd who laid down His life for God’s flock. I would like this greeting of peace to resound in your hearts, in your families, among all people, wherever they may be, in every nation and throughout the world. Peace be with you!
It is the peace of the risen Christ. A peace that is unarmed and disarming, humble and persevering. A peace that comes from God, the God who loves us all, unconditionally. '' (Vatican News)
We add to our joy that the Pope is a religious from the Order of St Augustine ! He quoted the saint who said: “With you I am a Christian, and for you I am a bishop''. In this sense, all of us can journey together toward the homeland that God has prepared for us'' , continued the first American-born Pope. (Vatican News)
May Blessed Marie-Catherine of Saint-Augustine intercede for him throughout his pontificate, as a little sister through Saint Augustine, united in Christ. Long live the Pope!


Discover the coat of Arms of the Holy Father
Adorned with pontifical insignia, the coat of arms includes the keys of Peter, in gold and silver, in reference to the power to bind and loose granted by Christ to the apostle and his successors. The second pontifical insignia is the miter, which replaces the cardinal's hat present on the emblem of the man who was previously called Cardinal Robert Francis Prevost.
Pope Leo's coat of arms reflects his Augustinian heritage and his Marian devotion. The coat of arms is divided diagonally into two sections: a blue section with a white fleur-de-lis, symbolizing the Virgin Mary. The new pontiff's love for the Virgin Mary was evident from his first public appearance, when he movedly entrusted the Church to Mary and invited the crowd to recite a Hail Mary; May 8th is also the feast of Our Lady of the Rosary of Pompeii and, for us, the feast of Blessed Mary Catherine of Saint Augustine.
The lower part features a red heart pierced by an arrow, resting on a closed book, a symbol of Saint Augustine's conversion, his experience of God's love and of his Word in it. In our Marian exhibition, Hail… Our Lady! , we have a stole bearing the symbol of the heart pierced by an arrow, recalling the Saint's words: You have pierced my heart with your Word (Confessions, Book X, VI, 8) and You pierced our hearts with the arrows of your charity, and we carried your words, planted in our entrails. (Confessions, Book IX, II, 3)
His motto, IN ILLO UNO UNUM, ("In the One, we are One"), is taken from a commentary by Saint Augustine on Psalm 127. This clearly reflects his Augustinian roots, and in particular, the unity and communion within the Church and in Christ. One heart and one soul. (Acts of the Apostles; 4:32-37); a phrase echoed at the opening of the Rule of Saint Augustine: “Above all, live in unity at home, with one mind and one heart turned toward God. Is this not the reason for your gathering?”
As Cardinal Prevost himself explained, '' unity and communion are part of the charism of the Order of Saint Augustine and also of my way of acting and thinking. I believe it is very important to promote communion in the Church, and we know very well that communion, participation, and mission are the three key words of the Synod. Therefore, as an Augustinian, promoting unity and communion is fundamental to me. Saint Augustine speaks a lot about unity in the Church and the need to live it.” (Vatican news 2023)
Augustine had a great desire for a common life, and (around 391?) established a monastery, living with his brothers according to the Rule of the Apostles. For Saint Augustine, this common life reflects the unity of the Trinity. "Whatever the Father, the Son, and their common Spirit do, they do together, all equally and in perfect harmony." (Saint Augustine, Trinitate, XIII, 11, 15)
We find in the Gospel according to Saint John, chapter 17, verse 21, "That they may all be one, as you, Father, are in me, and I in you. That they also may be one in us, so that the world may believe that you sent me." and in John 10:30, "The Father and I are ONE." The pontificate of Pope Leo calls us all to live according to the fact that the more we cling to Jesus, the more we find ourselves members of one another. And the more we conform ourselves to his humility and charity, the more his glory, that we are united in the unity of Christ, is manifested in the world. It is with the same hope that we work and move forward.
Through fraternal love, because God is love and charity, the Christian can have here below a certain experience of the Trinitarian mystery, and of the unity that unites the Father, the Son, and the Spirit.
"Therefore, if the charity of God in our hearts through the Holy Spirit who has been given to us makes many souls one soul and many hearts one heart, how much more are the Father, the Son, and the Holy Spirit one God, one light, and one Principle." » (Saint Augustine, Homilies on the Gospel of Saint John 39:5)
In the Church, the sacramental unity of the totus Christus, we are the mystical body of Christ who gathers the multitude into himself and makes them one.

'' I was chosen, without any merit of my own, and now, with fear and trembling, I come to you as a brother, who desires to be the servant of your faith and your joy, walking with you on the path of God’s love, for he wants us all to be united in one family. ''
