What Is a Saint? Saints and Holiness in Christianity
What is a saint? Discover the biblical meaning of the word, how churches use it today, and the key Catholic, Orthodox, and Protestant perspectives.
What does the word saint mean?
In Christianity, the word “saint” commonly refers to someone regarded as holy, devoted to God, or set apart in a special way. The background of the term lies in the Greek word hagios in the New Testament. It carries the sense of “holy,” “set apart,” or “belonging to God.” So the first answer to the question “What is a saint?” is broader than many people expect. It did not originally refer only to famous spiritual heroes.
This is clear in the New Testament letters. In Romans 1:7, Paul addresses believers with language translated as “saints” or “holy ones.” The same pattern appears in Ephesians 1:1 and Philippians 4:21-22. In those passages, the word does not point only to a few extraordinary people. It is used for the community of believers. First Corinthians 1:2 and Colossians 1:2 support the same idea. In its earliest biblical use, “saints” is first of all a communal identity.
In the New Testament, “saints” first describes all believers as people who belong to God; only later did the term take on a narrower and more specialized use. Romans 1:7, Ephesians 1:1, Philippians 4:21-22
That detail matters. In Christian belief, holiness is not usually presented as mere human achievement. Many church traditions connect holiness with God’s calling and transforming work. In that sense, the word “saint” speaks both of a status and of a way of life.
Why does the Bible use it for all believers?
In the earliest Christian communities, identity was shaped less by ethnicity or social rank and more by belonging to Christ. That is why Paul can speak of the believers in Rome, Ephesus, or Philippi as “saints.” He is not claiming they were flawless people. He is saying they were marked out as God’s people.
Passages such as 1 Peter 2:9 and Hebrews 10:10 fit this wider picture of holiness. Of course, that does not mean every believer lived with the same maturity. The New Testament letters are full of correction, warning, and pastoral instruction. Even so, the term “saints” remains in use.
For that reason, many Christians still emphasize this broad meaning today. In Protestant settings especially, there is often strong attention to the New Testament pattern, where every true believer may in one sense be called a saint. That approach aims to stay close to the earliest biblical usage.

How did the meaning become narrower over time?
As church history developed, the everyday use of the word “saint” became more specific. One reason was that some believers stood out for remarkable faithfulness, service, sacrifice, or endurance in suffering. Early martyrs were especially remembered in this way. Later, teachers, monks, nuns, bishops, and other Christians seen as models of holy living were also honored under the same title.
The underlying idea was simple: all believers are called to holiness, but some lives become especially memorable examples of that calling. So the word kept its broad biblical background while also taking on the sense of an exemplary Christian in the life of the church.
You can still see traces of this in church names and city life. “Aya” and “Hagia” come from forms meaning “holy.” “San” reflects the Latin tradition of naming a saint. “Surp” is the Armenian Christian word for “holy.” In Istanbul, church names such as Aya Irini, Ayia Triada, or churches beginning with Surp preserve this memory in public space. If you want to explore those living traces, the churches guide offers a practical way to discover places from different traditions.
The idea of sainthood is not only a title; in many Christian traditions it is a shared memory of lives remembered for faith, perseverance, and service. Hebrews 12:1
Catholic, Orthodox, and Protestant perspectives
Today, Christians do not use the word “saint” in exactly the same way. In the Catholic Church, sainthood is connected with a formal process of recognition often called canonization. In that process, the person’s life, teaching, witness, and reputation are examined. The goal is to recognize that person as an exemplary witness for the wider church.
In Orthodox tradition, saints are also deeply honored, but the emphasis often rests more on the church’s living worship, long-standing devotion, and recognition within the life of the community. Different Orthodox churches may follow patterns that lead to similar results, even if the process is not always described in the same centralized terms found in the Catholic world.
Catholic and Orthodox Christians do not usually see saints as merely admirable historical figures. They are understood as living witnesses in Christ. Because of that, honoring saints and asking for their prayers, often described as intercession, has a place in those traditions. Officially, this honor is not meant to be the same as worship given to God; it is framed as reverence for what God has done in human lives.
Protestant approaches are generally different. Many Protestants, appealing to passages such as 1 Timothy 2:5, stress direct prayer to God. For that reason, praying to saints or asking for their intercession is usually not practiced. At the same time, many Protestants still respect Christians from the past who lived with notable faithfulness, even if they do not place them within a formal framework of intercession.
The fairest way to understand these differences is not to force one tradition’s language onto another, but to see the theological logic each tradition is trying to preserve. For a broader historical window, the article on the Greek Orthodox Church: history and tradition can offer useful background.
What does sainthood say to us today?
Today, the question “What is a saint?” is more than a historical curiosity. It opens a larger conversation about how Christianity understands holiness. Some traditions foreground the calling shared by all believers. Others keep that wider meaning while also honoring certain Christians in a distinctive way. The common thread is that sainthood is tied not to fame alone, but to faith, love, endurance, truthfulness, and a life devoted to God. Passages such as Galatians 5:22-23 and James 2:17 help explain why the link between faith and life matters so much.
As you walk through Istanbul, names like Aya, Hagia, San, and Surp are quiet reminders of that long memory. A church name is not only an architectural label. It can also carry centuries of prayer, devotion, and communal remembrance. Learning about saints, then, is not only about defining a term. It is also about noticing how Christian history lives on in worship, language, and place.
If you want to see those traces more concretely, you can browse the churches page and explore places connected with different Christian traditions in the city. It is one of the clearest ways to see that the language of sainthood still lives not only in books, but also in the memory of neighborhoods and churches.
Is a saint the same as a holy person in a general sense?
There is some overlap, but in Christianity the word “saint” has a specific biblical and historical background. It is shaped by the New Testament, church memory, and the teachings of different traditions.
Is every Christian a saint?
In the New Testament, the word “saints” is often used for all believers, including Romans 1:7, Ephesians 1:1, and Philippians 4:21-22. Over time, however, some church traditions also began using the word in a more specific sense for Christians remembered for especially exemplary lives.
Why do Catholics and Orthodox Christians honor saints?
In those traditions, saints are seen as examples of God’s work in human lives and as living witnesses in Christ. For that reason, they are honored, and in many communities their intercession is requested, while most Protestants prefer to direct prayer to God alone.
