These are the ones who, living in the flesh, planted the Church with their blood; they drank the chalice of the Lord and became the friends of God.

O God, who on the Solemnity of the Apostles Peter and Paul give us the noble and joy of this day, grant we pray, that your Church may in all things follow the teaching of those through whom she received the beginnings of right religion.

The antiphon and Collect set the tone by noting our belief: the Church is built on the life, work and sacrifice of two men in collaboration with Christ. It is, as Benedict says,  truth is one and symphonic (an idea taken from von Balthasar). How do we live this reality?

Today’s solemnity brings with it a wonderful remembrance of how God uses unsuspecting people to witness to his truth and power. The Pope has “traditionally” bestowed the pallium on the new archbishops as a sign of communion with him in serving the Church and a share in the Cross. North America has several new metropolitan archbishops who went to Rome to pray at the tombs of these Apostles and to receive from the Holy Father this beautiful symbol of office.

Two paragraphs below are taken from the Holy Father’s homily, but the entire text may be read here:

Madonna, Child and Peter and Paul GCesari.jpg

In front of Saint Peter’s Basilica, as is well known,
there are two imposing statues of Saint Peter and Saint Paul, easily
recognizable by their respective attributes: the keys in the hand of Peter and
the sword held by Paul. Likewise, at the main entrance to the Basilica of Saint
Paul Outside the Walls, there are depictions of scenes from the life and the
martyrdom of these two pillars of the Church. Christian tradition has always
considered Saint Peter and Saint Paul to be inseparable
: indeed, together, they
represent the whole Gospel of Christ
. In Rome, their bond as brothers in the
faith came to acquire a particular significance. Indeed, the Christian
community of this City considered them a kind of counterbalance to the mythical
Romulus and Remus, the two brothers held to be the founders of Rome. A further
comes to mind, still on the theme of brothers: whereas the first
biblical pair of brothers demonstrate the effects of sin, as Cain kills Abel,
yet Peter and Paul, much as they differ from one another in human terms and
notwithstanding the conflicts that arose in their relationship, illustrate a
new way of being brothers, lived according to the Gospel, an authentic way made
possible by the grace of Christ’s Gospel working within them
. Only by following
does one arrive at this new brotherhood: this is the first and
fundamental message that today’s solemnity presents to each one of us, the
importance of which is mirrored in the pursuit of full communion, so earnestly
desired by the ecumenical Patriarch and the Bishop of Rome, as indeed by all

Dear Metropolitan Archbishops, the Pallium that I have conferred on you will always remind you that you have been constituted in and for the great mystery of communion that is the Church, the spiritual edifice built upon Christ as the cornerstone, while in its earthly and historical dimension, it is built on the rock of Peter. Inspired by this conviction, we know that together we are all cooperators of the truth, which as we know is one and “symphonic”, and requires from each of us and from our communities a constant commitment to conversion to the one Lord in the grace of the one Spirit. May the Holy Mother of God guide and accompany us always along the path of faith and charity. Queen of Apostles, pray for us!
