via the Vatican:

Every good and worthwhile human activity is in some way a reflection of God’s infinite beauty, and sport is certainly one of these. For God is not immobile and closed in on himself, but activity, communion, a dynamic relationship between the Father, the Son and the Holy Spirit, which opens up to humanity and to the world. Theologians speak of perichoresis: the life of God is a kind of “dance”: a dance of mutual love.

This dynamism of God’s inner life gives birth to life. We were created by a God who finds joy in giving existence to his creatures, who “delights” in our world, as the we heard in the first reading (cf. Prov 8:30-31). Some Fathers of the Church go so far as to speak of a Deus ludens, a God who “plays” (cf. SAINT SALONIUS OF GENEVA, In Parabolas Salomonis expositio mystica; SAINT GREGORY NAZIANZEN, Carmina, I, 2, 589). Sport can thus help us to encounter the Triune God, because it challenges us to relate to others and with others, not only outwardly but also, and above all, interiorly. Otherwise, sport becomes nothing more than an empty competition of inflated egos….

From this standpoint, let us reflect on three particular things that make sport, nowadays, a precious means for training in human and Christian virtues.

First, in a society marked by solitude, where radical individualism has shifted the emphasis from “us” to “me”, resulting in a deficit of real concern for others, sport – especially team sports – teaches the value of cooperating, working together and sharing. These, as we said, are at the very heart of God’s own life (cf. Jn 16:14-15). Sport can thus become an important means of reconciliation and encounter: between peoples and within communities, schools, workplaces and families.

Second, in an increasingly digital society, where technology brings distant people closer together, yet often creates distances between those who are physically close, sport proves a valuable and concrete means of bringing individuals together, providing a healthier sense of the body, of space, effort and real time. It counters the temptation to escape into virtual worlds and it helps to preserve a healthy contact with nature and with real life, where genuine love is experienced (cf. 1 Jn 3:18).

Third, in our competitive society, where it seems that only the strong and winners deserve to live, sport also teaches us how to lose. It forces us, in learning the art of losing, to confront one of the deepest truths of our human condition: our fragility, our limitations and our imperfections. This is important, because it is through the experience of these limits that we open our hearts to hope. Athletes who never make mistakes, who never lose, do not exist. Champions are not perfectly functioning machines, but real men and women, who, when they fall, find the courage to get back on their feet.
