Today is the feast of St. Peter and Paul, Apostles. From Pope Leo XIV's homily for the day:
In this light, we can interpret the mission entrusted by the Lord to Peter and his Successors for the benefit of the entire holy People of God. It is a mission to listen, with his help, to the voice of each person; to discern inspirations; to guide the way; to correct errors; to instruct, encourage, exhort and accompany our brothers and sisters so that, docile to the action of the same Spirit (cf. 1 Cor 12:1–11), they may cooperate in the salvation of one another and of all humanity. Moreover, Peter’s example is an invitation to every Christian to become a builder of unity, placing God at the center of one’s life and drawing close to one’s brothers and sisters, attentive to their circumstances and needs (cf. Francis, Catechesis, 9 October 2024). In this way, we learn to live with one another in charity, so that the message might be fully proclaimed (cf. 2 Tim 4:17).
This is also the teaching of Paul, the other great apostle we celebrate today and the tireless herald of the Good News. He, too, has distinctive symbols: the book and the sword, which are closely linked to one another. The author of the Letter to the Hebrews explains this well when he writes that, “the word of God is living and active, sharper than any two-edged sword,” capable of penetrating “until it divides soul from spirit” and of discerning “the thoughts and intentions of the heart” (Heb 4:12).
From one of Pope St. Leo I's homilies for the feast:
The whole world, dearly-beloved, does indeed take part in all holy anniversaries, and loyalty to the one Faith demands that whatever is recorded as done for all men's salvation should be everywhere celebrated with common rejoicings. But, besides that reverence which today's festival has gained from all the world, it is to be honoured with special and peculiar exultation in our city, that there may be a predominance of gladness on the day of their martyrdom in the place where the chief of the Apostles met their glorious end. For these are the men, through whom the light of Christ's gospel shone on you, O Rome, and through whom you, who was the teacher of error, was made the disciple of Truth. These are your holy Fathers and true shepherds, who gave you claims to be numbered among the heavenly kingdoms, and built you under much better and happier auspices than they, by whose zeal the first foundations of your walls were laid: and of whom the one that gave you your name defiled you with his brother's blood. These are they who promoted you to such glory, that being made a holy nation, a chosen people, a priestly and royal state, and the head of the world through the blessed Peter's holy See you attained a wider sway by the worship of God than by earthly government. For although you were increased by many victories, and extended your rule on land and sea, yet what your toils in war subdued is less than what the peace of Christ has conquered.
