The biblical Greek and Hebrew words sometimes translated as “saints” mean literally “holy ones” (Act 9:13) or “faithful ones” (1 Sm 2:9). Typically, these are general terms for God’s people, who have a share in his holiness and are striving to become more holy (see Heb 12:10; 2 Cor 7:1). The apostle Paul was especially fond of addressing his letters to “all the holy ones” in the churches (2 Cor 1:1).
All faithful Christians, then, are indeed “saints” in this sense. In fact, the Catholic Church teaches that the vocation to holiness is universal; God speaks to all believers when he says: “Be holy because I [am] holy” (see 1 Pt 1:14-16).
It is in this latter, narrower, sense that the Catholic Church honors certain departed Christians with the formal title “saint.” This title indicates the Church’s confidence that the individual died in friendship with God and is now in heaven with him (see “What Does the Church Teach About Heaven?”).
Why is it important for the Church to designate certain Christians this way? “Saint” is actually much more than a title of honor. Because the Church is confident that these “holy ones” are now in heaven, Catholics are urged not only to venerate them, but also to imitate their holiness and ask for their intercession (see “Why Do Catholics Pray to Saints and Angels?”).
How does the Church gain the confidence that a particular person is in heaven? Various kinds of evidence are sough in the process of “canonization” (for recognition of sainthood): reliable testimony to the person’s extraordinary holiness, evidence that the person’s life has drawn others closer to God, and documented miracles occurring after the the person’s intercession has been invoked (see also “Hasn’t Science Disproved Miracles?”).
