World Communion Sunday

Definition and Meaning

World Communion Sunday is a day on which many churches celebrate Communion on the same Sunday to express the confession that Christians are one body regardless of denomination or nationality. It is generally observed on the first Sunday of October. Communion is a sacrament in which bread and wine (or grape juice) are shared in remembrance of the death and resurrection of Jesus Christ. Among the meanings of Communion, World Communion Sunday places particular emphasis on fellowship and unity. Unlike observances such as Advent or Easter, which date from ancient times, it is a commemorative Sunday that originated in the twentieth century.

Biblical and Historical Background

Passages frequently cited as the basis for this day include 1 Corinthians 10:17, "For we being many are one bread, and one body"; the words instituting the Lord's Supper in 1 Corinthians 11:23–26; and Jesus' prayer for the unity of his disciples in John 17:21.

World Communion Sunday is generally believed to have begun in the 1930s at Shadyside Presbyterian Church in Pittsburgh, Pennsylvania. According to tradition, it was first promoted by the church's pastor at the time, Hugh Thomson Kerr. The observance was intended to express the solidarity of the church amid the Great Depression and rising international tensions. It was subsequently adopted by American Presbyterians and is reported to have spread to other denominations around 1940 through an American ecumenical church body. Because of this history, World Communion Sunday is understood as an observance linked to the ecumenical movement, which seeks cooperation across denominational lines.

Practice in Korean Churches

In Korea, many churches celebrate Communion on the first Sunday of October. Denominations active in ecumenical work, such as the Presbyterian Church of Korea (Tonghap), the Korean Methodist Church, and the Presbyterian Church in the Republic of Korea, often include the day in their liturgical calendar materials or worship resources. In other denominations, observance is left to the discretion of individual congregations. Among Korean churches that celebrate Communion only a few times a year, some have made World Communion Sunday a regular Communion day alongside Easter and Christmas. Participation in Communion is generally restricted to baptized members, although the specific criteria vary by denomination and congregation.

Although Communion is shared on the same day, understandings of it differ among denominations.

• Presbyterian: The predominant view follows the Calvinist tradition, which holds that Christ is spiritually present through the Holy Spirit.
• Methodist: Follows the Wesleyan tradition, which values Communion as a means of grace.
• Baptist: Generally calls it "the Lord's Supper" and emphasizes its memorial character as a remembrance of Christ's death.
• Anglican Church of Korea: Because many of its churches celebrate the Eucharist every Sunday, this day may not differ significantly in form from other Sundays.

These differences are discussed in more detail in the article on Eucharistic controversies. In addition, because the observance originated in the ecumenical movement, the degree of emphasis placed on the day also varies by denomination and congregation.
