The Catechism of the Catholic Church (CCC) presents saintliness as the universal call to holiness given to all the baptized, who are invited to live in union with Christ through faith, charity, purity of heart, and self‑control;
it emphasizes that sanctity is not reserved for a few but is the vocation of every Christian,
expressed in daily fidelity to God’s commandments, prayer, and love of neighbor, and perfected in the imitation of Christ and the saints (cf. CCC 2013–2014).
