Saints, Relics & Canonization
Why Catholics ask saints to pray, venerate relics, recognize martyrs and Doctors, investigate miracles, and canonize saints without pretending every pious legend is history.
Catholics venerate saints because the holiness of God truly bears fruit in His people. Saints are not worshiped, and relics are not magic objects. Canonization is the solemn act by which the Roman Pontiff declares a member of the faithful to be a saint and extends that saint’s veneration to the universal Church. Catholic theologians commonly hold the definitive judgment involved in canonization to be protected from error; that theological conclusion should not be mislabeled as a revealed dogma. Extraordinary phenomena such as incorruption or stigmata are secondary and require careful discernment.

Make the case
Define the claim accurately, state the strongest fair objection, and use the evidence without shortcuts.
Biblical logic of relics
Scripture contains episodes in which God acts through material contact associated with holy persons without turning the material object into a deity.
Sources: 2 Kings 13:20–21 — Douay-Rheims; Acts 19:11–12 — Douay-Rheims.
Canonization procedure
Modern causes are investigated at the local level and then examined through the Dicastery for the Causes of Saints under norms governing evidence, virtue, martyrdom, offering of life, and miracles.
Sources: St. John Paul II, Divinus Perfectionis Magister, (25 January AD 1983); Congregation for the Causes of Saints, Normae servandae in inquisitionibus ab Episcopis faciendis in Causis Sanctorum (7 February AD 1983); Congregation for the Causes of Saints, Sanctorum Mater, arts. 1–10 (17 May AD 2007); Francis, Maiorem hac dilectionem, arts. 1–6 (11 July AD 2017).
Relic authenticity and preservation
The Holy See regulates the authentication, conservation, transfer, and division of relics; devotional enthusiasm does not substitute for documentation.

Use it in a real conversation
One claim. One distinction. One strong anchor.
The Church honors saints as works of grace, investigates causes before canonization, and venerates relics without worshiping created objects.
A saint’s holiness can be certain for the Church without every medieval legend or extraordinary phenomenon being historically certain.
Use Acts 19, CCC 946–962, and the current causes-of-saints norms.
What not to say
Avoid: “Asking a saint proves we need someone other than Christ to save us.”
A better approach: Distinguish Christ’s unique saving mediation from the intercessory prayer of his members. Explain why Catholics think death does not end that communion.
Questions people actually ask
Every substantive answer carries direct source anchors.
What determines whether someone is named a saint?
Canonization is the Church’s definitive act enrolling a person among the saints for veneration in the universal Church. Modern causes involve a diocesan or eparchial investigation, Roman study through the Dicastery for the Causes of Saints, examination of heroic virtue, martyrdom, or an approved offering of life, and ordinarily miracles according to the applicable norms. The Pope makes the final act of canonization.

Why do Catholics keep relics?
Catholics venerate relics because the human body belongs to a person created and redeemed by God, and because Scripture records God working through material things associated with holy persons. Relics are not worshiped as gods. The Church also regulates their authenticity, preservation, transfer, and public veneration.

What is a martyr and who are some martyrs that affected the Church?
A martyr is one who freely accepts death rather than deny Christ or a truth of Christian faith. From the apostolic age onward, martyrdom has been regarded as the supreme witness to Christ.
Sources: Revelation 6:9–11 — Douay-Rheims; Catechism of the Catholic Church 2473–2474.
What does the title Doctor of the Church mean?
Doctor of the Church is a title given to certain saints whose holiness and theological or spiritual teaching are of outstanding importance for the universal Church. It is not an academic degree awarded after death.
Sources: Benedict XVI, Apostolic Letter declaring St. John of Avila a Doctor of the Universal Church (7 October AD 2012); Francis, Apostolic Letter declaring St. Irenaeus Doctor Unitatis (21 January AD 2022).
Who is the devil’s advocate?
The historical ‘devil’s advocate’ was the promoter of the faith’s office that critically tested evidence in causes of canonization. Modern procedures use different structures, but the principle of rigorous examination remains.
Sources: St. John Paul II, Divinus Perfectionis Magister; Congregation for the Causes of Saints, Normae servandae in inquisitionibus ab Episcopis faciendis in Causis Sanctorum (7 February AD 1983).

What is an incorruptible saint?
An incorrupt body is a reported preservation of a saint’s remains beyond what observers expected. Such phenomena are not themselves dogmas, do not prove sanctity by themselves, and must be judged carefully.
Sources: Dicastery for the Causes of Saints, Relics in the Church: Authenticity and Preservation.
Discipline check: Catholic-Church; verified 2026-08-12.
What is stigmata?
Stigmata refers to extraordinary bodily marks resembling the wounds of Christ. Reports are evaluated prudently; even authentic private phenomena are secondary to holiness, faith, and charity.
Sources: Galatians 6:17 — Douay-Rheims; Catechism of the Catholic Church 2014.
What are bilocation and levitation?
Bilocation is the reported presence of a person in two places in an extraordinary manner, and levitation is extraordinary bodily elevation. Accounts associated with saints are not articles of faith and require sober discernment rather than sensationalism.
Sources: Catechism of the Catholic Church 2014; St. John of the Cross, The Ascent of Mount Carmel II.11.
Why did Saint Christopher get thrown out of the church?
St. Christopher was not ‘thrown out of the Church.’ His cult remained part of Catholic tradition, but the 1969 revision of the General Roman Calendar removed his celebration from the universal calendar because the universal calendar is selective and because of limited historical data. Local veneration may continue where legitimately established; removal from the general calendar is not a declaration that a saint never existed.
Sources: Paul VI, Mysterii Paschalis; General Roman Calendar.
What is the Roman martyrology?
The Roman Martyrology is the Church’s official liturgical catalogue of saints and blesseds commemorated through the year. It is broader than the General Roman Calendar and records many holy men and women not celebrated universally with their own feast.
