What Are Communion Wafers Made Of? Names, Ingredients, and Gluten

Traditional communion wafers, also called hosts, are made only of wheat flour and water, then baked thin without yeast. That simple recipe and baking method are why classic holy communion wafers are flat, white, and long-lasting.

At CFaithS, we know churches, chapels, schools, and families often need a clear answer before choosing host bread for worship. This guide explains the names, the ingredients, Catholic requirements, Protestant variations, gluten notes, and practical storage tips.

What are communion wafers called?

Communion wafers are most often called hosts, but people also use the names altar bread, communion bread, wafers, and host bread. In Catholic use, “host” comes from the Latin hostia, meaning victim or sacrifice, pointing to the Eucharistic meaning of Christ’s sacrifice.

Common names include:

1. Hosts: the traditional Catholic term for communion wafers.
2. Altar bread: bread prepared for use at the altar.
3. Communion bread: a broad phrase used across many Christian traditions.
4. Wafers: a simple descriptive term for thin, round pieces of bread.
5. Priest’s hosts: larger hosts, often about 2–3 inches, used by the celebrant.
6. People’s hosts: smaller hosts distributed to the congregation.

These names often overlap when churches order supplies. A Catholic parish may look for altar breads or hosts, while another Christian church may look for communion bread, wafers, or prefilled communion cups with wafers.

The traditional ingredients are intentionally simple

Traditional hosts contain wheat flour and water only. No yeast is added, so the dough does not rise. No sugar, honey, oil, seasoning, or flavoring is part of the standard Catholic host recipe.

This simplicity is both practical and theological. Practically, the thin baked wafer is easy to store, count, distribute, and consume reverently. Theologically, in the Latin Catholic tradition, the use of unleavened wheat bread connects the Eucharist with the Last Supper and the Church’s liturgical law.

The usual ingredients for traditional Catholic hosts are:

1. Wheat flour — the grain required for Catholic Eucharistic bread.
2. Water — used to form the dough.
3. No leavening — no yeast, baking powder, or rising agent.
4. No added ingredients — no sweeteners, oils, fruits, flavorings, or fillers.

Because the recipe is so plain, hosts taste neutral and feel crisp rather than soft. That is normal for hard unleavened wafers.

Catholic requirements for communion bread

For the Roman Catholic Church, communion bread is not simply a preference or style choice. The Code of Canon Law (canon 924) states that the bread must be wheat only and recently made, and canon 926 reflects the Latin Church’s tradition of using unleavened bread. The General Instruction of the Roman Missal (no. 320) likewise says the bread for the Eucharist must be made only from wheat, recently made, and unleavened.

In practical terms, Catholic altar bread must be:

1. Made of wheat only
2. Unleavened
3. Recently made
4. Free from other additions
5. Suitable for reverent liturgical use

Church documents also warn against adding other substances such as fruit, sugar, or honey to Eucharistic bread, because those additions change what the bread is for the purposes of the sacrament.

Eastern Catholic and Orthodox churches follow a different liturgical tradition and commonly use leavened bread for communion. That difference is not a small detail; it reflects distinct rites, customs, and theological symbolism. For Catholic buyers, the key is to choose bread appropriate to the rite and parish practice.

How communion hosts are made

The process for making traditional host bread is straightforward, but it requires care and consistency. Wheat flour and water are mixed into a simple dough or batter. That mixture is then baked between heated plates, which press it thin and cook it evenly into sheets or rounds.

After baking, the sheets are cut into individual hosts. Larger rounds become priest’s hosts, while smaller rounds become people’s hosts. Production is often done by religious communities, including monasteries and convents, as well as trusted church-supply producers who understand the importance of reverence, consistency, and correct ingredients.

A typical process looks like this:

1. Mix wheat flour and water until smooth and usable.
2. Bake the mixture between heated plates to create thin wafers.
3. Cool the baked sheets or rounds so they firm properly.
4. Cut them into standard sizes for clergy and congregation.
5. Package them to keep the hosts clean, dry, and ready for church use.

The result is the familiar white, flat wafer used in many Catholic parishes and other Christian services.

Protestant communion practices vary widely

Many Protestant churches use communion wafers, but practices vary much more widely than in Catholic sacramental law. Some congregations use soft unleavened bread. Others use crackers, cubes of bread, or a shared loaf that is broken during the service.

Some churches also use prefilled communion cups with a wafer sealed in the top section, especially when sanitation preferences, outdoor services, hospital ministry, or large gatherings make individual servings helpful. In those settings, the exact ingredients depend on the church’s tradition, the producer, and the product label.

That variety means one church’s “communion bread” may look very different from another’s. If your congregation has a specific theological or denominational requirement, confirm it with your pastor, worship leader, or church office before ordering.

Do communion wafers contain gluten?

Traditional wheat hosts contain gluten because they are made from wheat. In Catholic practice, low-gluten hosts may be used only when they still contain enough gluten to qualify as wheat bread for the Eucharist, without foreign materials or processes that change the nature of bread.

Many Protestant churches, by contrast, use products labeled gluten-free, depending on their own church practice. Product labels may describe items as “low-gluten,” “gluten-free,” “wheat,” or “not wheat,” so read each listing carefully rather than assuming all wafers are the same.

For a fuller overview of label language and Catholic low-gluten hosts, see our guide to gluten-free communion wafers and Catholic low-gluten hosts. Anyone with a gluten concern should check the label and speak with their pastor about what is appropriate for communion in their church.

Freshness and storage matter

Even though traditional hosts are thin and long-lasting, they should still be stored carefully. Keep communion wafers in airtight containers or tightly sealed packaging, in a cool, dry place away from humidity, heat, strong odors, and open air.

Good storage keeps the wafers from becoming stale, soft, or affected by moisture. For parishes and ministries, rotate stock so older packages are used first. Before Mass or service, check that the hosts look clean, dry, intact, and suitable for reverent use.

A simple storage checklist:

1. Keep hosts sealed until needed.
2. Use airtight containers after opening.
3. Store in a cool, dry cabinet.
4. Avoid refrigeration unless the producer specifically instructs it.
5. Keep wafers away from incense, candles, cleaning products, and food odors.
6. Check product labels for any freshness guidance.

Choosing the right communion bread for your church

The right choice depends on your tradition, liturgical requirements, and how communion is served. A Catholic parish normally needs unleavened wheat hosts that meet Catholic requirements. A Protestant congregation may choose hard wafers, soft bread, crackers, a loaf, or prefilled cups depending on its practice.

Before ordering, consider:

1. Denomination or rite: Catholic, Orthodox, Eastern Catholic, Anglican, Lutheran, Baptist, Methodist, non-denominational, or another tradition.
2. Form: hard wafers, soft unleavened bread, larger celebrant hosts, smaller people’s hosts, or prefilled sets.
3. Ingredients: wheat-only, low-gluten, gluten-free-labeled, or another church-approved option.
4. Serving size: small congregation, school Mass, chapel, retreat, hospital ministry, or large parish.
5. Storage needs: how often communion is served and how quickly supplies are used.

When in doubt, ask your pastor or church leadership before purchasing.

A simple takeaway for churches and families

Traditional hosts are made of wheat flour and water, baked thin without yeast. The details matter, though, because Catholic, Orthodox, Eastern Catholic, and Protestant communities use different forms of communion bread according to their own traditions.

For Catholic use, look for unleavened wheat hosts with no added ingredients. For Protestant use, confirm your church’s practice and read product labels carefully, especially when gluten is a concern.
