What does the 'universal call to holiness' mean?

The phrase has two key words, and both carry weight. Universal means it leaves no one out: this call goes to everyone in the Church, whatever their state of life, work, or background. Holiness means becoming perfect in charity — letting love of God and neighbour grow until it shapes the whole person. Put together, the teaching says that the highest goal of the Christian life is meant for absolutely everybody.

This idea received fresh emphasis at the Second Vatican Council, especially in its document Lumen Gentium. For centuries many people had quietly assumed a two-tier system: a higher, "really holy" track for monks and nuns and priests, and a lower, ordinary track for everyone else. The Council insisted that this is a misreading. There is one calling, and it is addressed to the married and the single, the labourer and the professor, the young and the old alike. Picture a single invitation to one destination, but with many routes leading there — mountain trails, coastal roads, city streets. The destination is identical for all; the road each person travels is their own life, with its particular duties and loves.

So holiness is not measured by how "religious" your circumstances look, but by how completely love takes over the circumstances you actually have. The point is not to copy a monk's schedule if you are a parent, or a parent's life if you are a monk, but to let charity perfect your vocation. A useful image is an apprentice in a master craftsman's workshop. The apprentice doesn't become skilled by reading about the trade or by leaving the workshop, but by working at the bench day after day, hands guided by the master, until the master's skill becomes the apprentice's own. Holiness grows the same way: by staying close to Christ through prayer, the sacraments, and daily faithful love, until his way of loving slowly becomes ours.

It is worth stressing that this is not a heroic demand we meet by sheer effort. The same teaching makes clear that holiness is the fruit of grace — God's life in us — to which we respond and cooperate. We cannot do it on our own, and we are never asked to. Cut off from Christ, the tradition says, we can produce nothing of lasting worth; joined to him, ordinary people in ordinary lives become saints. The universal call to holiness, then, is both a high calling and a deeply hopeful one: the goal is the greatest thing imaginable, and the power to reach it is given, not demanded of our own resources.

This teaching reshapes how a person sees their own life. It means your job, your family, your daily routine are not obstacles to holiness or a lesser substitute for it — they are the very arena where you are meant to become a saint. It rules out both pride (as if some vocations were spiritually superior) and resignation (as if holiness were beyond ordinary people). Everyone is aimed at the summit, and everyone's own path leads there.

• Matthew 5:48 — Jesus addresses the call to be "perfect" to all his hearers, not a select few.
• 1 Thessalonians 4:7 — God calls us "not to impurity but to holiness," naming holiness as the purpose of the Christian calling.
• Romans 8:29 — God's plan is to conform believers "to the image of his Son," describing the goal of holiness.
• John 15:5 — "apart from me you can do nothing," grounding holiness in staying united to Christ rather than self-effort.
• Colossians 3:14 — over every other virtue, "put on love," which "binds everything together," echoing holiness as the perfection of charity.

• CCC 2013, 2014
• The Second Vatican Council's Lumen Gentium (ch. 5) is the touchstone text: it teaches that all the faithful, whatever their condition, are called to the fullness of Christian life and the perfection of charity.
