Etymology

Communion is from the Latin communio, from com (together) and unio (union)[1]. The literal sense is sharing or union. In Christian usage the term has two main meanings: the sacrament of the Eucharist (Holy Communion) and the fellowship of believers (the communion of saints, the communion of the church)[2]. Both senses share the theme of being made one through shared participation.

A common misunderstanding

communion also carries the sense of fellowship and shared union within the body of believers.

In Practice

Holy Communion is one of the central Christian sacraments, also known as the Eucharist or the Lord's Supper[3]. The rite involves the consecration and distribution of bread and wine in remembrance of the Last Supper of Jesus with his disciples[4]. Different traditions interpret the meaning differently (real presence, memorial, spiritual presence, transubstantiation), but the practice is shared across most Christian traditions.

The frequency of Communion varies. Catholic Mass typically includes Communion daily; Eastern Orthodox Divine Liturgy centers on it[3]. Anglican and Lutheran traditions have weekly or more frequent celebration. Many Reformed and Baptist traditions celebrate monthly or quarterly. A few traditions (Quakers, Salvation Army) do not practice outward Communion, treating spiritual communion with Christ as direct without ritual.

The broader sense of communion as fellowship is central in Christian ecclesiology[2]. The communion of saints names the bond among all believers, living and dead, joined in Christ. The communion of churches is the relationship of full fellowship between recognized Christian bodies. Intercommunion (the practice of receiving Communion across denominational lines) is a major topic in modern ecumenical conversation, with significant differences in current practice[5].

Outside Christian usage, communion is occasionally extended to other traditions, but the term's primary religious meaning is Christian.

Scholarly Context

Eucharistic theology is one of the most extensively developed areas of Christian thought. The work cited under sacrament and eucharist applies[2]. Ecumenical conversations including the World Council of Churches' Baptism, Eucharist and Ministry document have explored mutual recognition and remaining differences[5].

Common Misconceptions

Misconception: Communion means the same thing in every Christian tradition.

Correction: Christian traditions hold significantly different theologies of Communion: real presence, transubstantiation, memorial, spiritual presence[2]. The shared practice masks deep differences.

Misconception: Anyone can receive Communion in any church.

Correction: Most traditions have rules about who may receive. Catholic Communion is open only to those in full communion with the Catholic Church; Eastern Orthodox practice is similar[3]. Protestant practice varies from open Communion (any baptized Christian) to more restrictive arrangements.
