Chalking the Door for Epiphany 2027: How to Do It, and the Reading That Goes With It

Somewhere in the second week of January you walk past a front door with a line of white chalk over it: 20 + C + M + B + 26. Or someone presses a small envelope into your hand after Mass, with a stick of chalk and a folded sheet of prayers inside. Either way the question is the same: what is this, and how do I do it at home without getting it wrong?

Here is all of it on one page: what to write for 2027, which day, what the letters mean, the Catholic, Episcopal and Methodist forms, and the short reading from Matthew underneath it all.

What chalking the door is, and who does it

Chalking the door is a house blessing kept at Epiphany. The household gathers at the front door, prays, and writes the new year and three letters over the entrance in chalk: Christ is welcome here for the year ahead.

The Catholic Church describes it in its own words. The Directory on Popular Piety and the Liturgy, published by the Vatican’s Congregation for Divine Worship in 2001, lists the blessing of homes among the customs of Epiphany (paragraph 118). Over the door goes the Cross, the year, and “the initials of the three wise men (C+M+B), which can also be interpreted to mean Christus mansionem benedicat, written in blessed chalk.”

The same paragraph adds something most how-to pages leave out. The custom is “often accompanied by processions of children accompanied by their parents” and is “an occasion for gathering offerings for charitable and missionary purposes.” So the Church’s own picture of it is a blessing and a gift: the door marked, and something given away.

According to a 2025 CNA guide in the National Catholic Register, the blessing is popular in Poland and other Slavic countries and increasingly so in the United States, where many parishes hand out chalk, holy water and the words of the blessing. Episcopal and United Methodist churches publish their own forms too.

When to chalk the door in 2027

The twelve days of Christmas run from Christmas Day to January 5, Twelfth Night. Epiphany is the day after the twelfth day. For 2027:

• Tuesday, January 5, 2027: Twelfth Night. The eve of Epiphany. Building Faith, from Virginia Theological Seminary, notes that Great Britain chalks the door on this night.
• Wednesday, January 6, 2027: Epiphany. The traditional date.
• Sunday, January 3, 2027: Epiphany for US Catholics. The US Conference of Catholic Bishops notes that in the United States the feast is celebrated “on the Sunday between January 2 and January 8.”

Pick the day your household can actually gather. If you want to read your way to it, a reading for each of the twelve days of Christmas ends on Twelfth Night, the evening before.

What 20 + C + M + B + 27 means

20 and 27 are the year, split in half. C, M and B sit in the middle. The + signs are crosses. Write it on the lintel, the beam across the top of the door frame.

The letters carry two meanings at once:

• Caspar, Melchior and Balthasar, the names Western Christians gave the magi. The United Methodist Church’s Discipleship Ministries puts it plainly: these names “are not to be found in Scripture.”
• Christus mansionem benedicat, Latin for “May Christ bless this house.” The Vatican’s Directory gives this as a second way to read the same letters.

How to chalk your door: a five-minute order for the household

The home blessings below are written for a household, with one person leading. Here is a simple order that borrows from them:

1. Get chalk. Any colour works. Building Faith suggests sidewalk chalk as “a particularly sturdy option.” If your parish blesses chalk, use that.
2. Gather at the front door. Catholic households may bring holy water.
3. Open with a greeting. The Episcopal form begins: “Peace be to this house, and to all who enter here.”
4. Read Matthew 2:1–12 aloud. About two minutes. (More on why below.)
5. Pray a blessing and the Lord’s Prayer together. Any of the prayers in the table below will do.
6. Write the inscription. Take turns, one mark each: 20 + C + M + B + 27.

The Methodist form adds a kind note: the marks usually go on the top of the frame, but “if younger children or people in wheelchairs participate,” they can place them anywhere on the frame they can comfortably reach.

Read Matthew 2:1–12 first: what the text says about the magi

The whole custom rests on one passage, the visit of the magi in Matthew 2:1–12. It is twelve verses long. In the Berean Standard Bible it runs to 271 words, which is about a minute and a quarter read silently at 220 words a minute, and about two minutes read aloud at around 140. Short enough to read at the door before anyone picks up the chalk. It is our suggestion; the published rites vary, as the table below shows.

The word Epiphany comes from Greek and, as Diane G. Chen of Palmer Theological Seminary writes in her Working Preacher commentary on this passage, it means manifestation. Stephen Hultgren of Australian Lutheran College notes in his commentary that in the Western Church the magi seem to have belonged to Epiphany “from the beginnings of the festival.” He also says who they stand for: “all the nations, including us, who would come to worship Jesus.” At your own door, that is you.

Read slowly and notice what the passage does not say.

• No number. Matthew never says there were three. As Chen puts it, “Later traditions simply assumed there were three of them, given the mention of three gifts.”
• No names. Mark Allan Powell of Trinity Lutheran Seminary writes in his Working Preacher commentary that in the Middle Ages the Western Church settled on three and named them Caspar, Melchior and Balthasar. The Eastern church, he notes, has twelve.
• No crowns. The kings came later. Powell links it to Isaiah 60:3; Hultgren calls it a later tradition shaped by Psalm 72:10–11.
• No manger. “On coming to the house, they saw the child with his mother Mary, and they bowed down and worshiped him” (Matthew 2:11, NIV). A house, which is why the magi are not at the manger in Matthew’s Christmas story.

None of this makes the letters wrong. Powell says such legends “are not insignificant for Christian piety,” though they “may distract us from the story Matthew tells.” Reading the twelve verses first keeps both in view. Matthew 2 is also day eight in the Christmas Bible verses read in order, if your household started there in December.

Catholic, Episcopal and Methodist forms, side by side

The forms are more alike than different. The Catholic bishops’ blessing prayer and the Episcopal one share almost the same words: “Lord God of heaven and earth, you revealed your only-begotten Son to every nation by the guidance of a star. Bless this house and all who inhabit it.” The Episcopal text says “God of heaven and earth” and “only-begotten One.”

One detail is worth knowing. The USCCB rite gives Luke 19:1–9, Zacchaeus welcoming Jesus to his house, as its example reading, and does not mention chalk at all. The chalk and its blessing come from the older Roman Ritual. CatholicCulture.org’s text of the 1952 Roman Ritual says it is traditional for parish priests to bless chalk for each family, notes that “any color of chalk is valid,” and has the chalk sprinkled with holy water.

Whether a household uses blessed chalk, holy water or neither is a matter for its own tradition. We are app builders, not pastors. If you are unsure what your church does, ask your priest or pastor, or use the BlessUp church finder to find a parish near you.

When the chalk fades

It will. Rain, a hand on the frame, a few weeks of winter, and the year starts to blur. The Methodist liturgy treats that as part of the point: chalk “will not permanently mar the dwelling. As its image fades from view over time, those who participated in its original placement will remember it.”

There is no rule about when to wipe it off. Some households let it wear away; others write over it next January. If you missed the day, chalk the door on the next evening you are all home. Nothing about the blessing expires on January 7.

Good intentions often go the same way: one bright evening at the door, then the weeks wear them thin. That is not failure. It is how most years go, and the answer is a smaller rhythm that can survive a missed day, the idea behind grace days instead of streaks that reset.

Frequently asked questions

What do you write when chalking the door for Epiphany 2027?

Write 20 + C + M + B + 27 over the front door, usually on the lintel. The numbers are the year split in half, the letters are the traditional initials of the magi, and the plus signs are crosses.

When do you chalk the door for Epiphany?

On Epiphany, Wednesday, January 6, 2027, or on its eve, Twelfth Night, Tuesday, January 5, as in Great Britain. US Catholics keep Epiphany on Sunday, January 3, 2027.

What does C+M+B stand for?

Caspar, Melchior and Balthasar, the names Western tradition gave the magi, though Matthew does not name them. The Vatican's Directory on Popular Piety says the letters can also mean Christus mansionem benedicat, May Christ bless this house.

Does the chalk have to be blessed?

The Catholic custom uses chalk blessed by a parish priest, and many parishes hand it out. Building Faith's Episcopal form says any colour of chalk will do, and the Methodist liturgy blesses the chalk at home. Follow your own church's practice.

Can Protestants chalk the door?

Many do. The Episcopal Church and the United Methodist Church both publish forms for it, built around prayer and a blessing of the home. If you are unsure, ask your pastor.

How long do you leave the Epiphany chalk on the door?

There is no set rule. Many households let it wear away, and the Methodist liturgy says that as it fades, those who wrote it will remember why. Next Epiphany, write the new year.
