Today we celebrate two brothers in faith, Peter and Paul, whom we honour as pillars of the Church and venerate as patrons of the diocese and city of Rome. (…) Today’s liturgy reminds us how Peter and Paul were called to share a single fate, that of martyrdom, which united them definitively to Christ. (…) Yet this communion of the two Apostles in the one confession of faith was the conclusion of a long journey on which each embraced the faith and lived out his apostolate in his own particular way. Their brotherhood in the Spirit did not erase their different backgrounds. (…) The history of Peter and Paul shows us that the communion to which the Lord calls us is a unison of voices and personalities that does not eliminate anyone’s freedom. (…) Saints Peter and Paul also challenge us to think about the vitality of our faith. In our life as disciples, we can always risk falling into a rut (…). The two Apostles, however, can inspire us by the example of their openness to change, to new events. (…)At the heart of today’s Gospel lies the question that Jesus asked his disciples. Today he asks us that same question, challenging us to examine whether our faith life retains its energy and vitality, and whether the flame of our relationship with the Lord still burns bright: “Who do you say that I am?” (Mt 16:15). Every day, at every moment in history, we must always take this question to heart. (…) Who is Jesus Christ for us today? What place does he occupy in our lives and in the life of the Church? How can we bear witness to this hope in our daily lives and proclaim it to those whom we meet? (Pope Leo XIV, Homily, 29 June 2025)
