Lutheran synods are regional or national associations of congregations that share common doctrinal confessions, mission programs, and ministerial oversight. In the United States, major Lutheran synods range from the mainline Evangelical Lutheran Church in America to confessional bodies like the LCMS and WELS, varying widely in their views on biblical inerrancy, women's ordination, and ecumenical fellowship.
What is a synod? Major Lutheran synods and governance
The term synod derives from the Greek compound word synodos, meaning "walking together" or "meeting on a common path." In historical Christian usage, a synod refers to an assembly of clergy and lay delegates gathered to deliberate on doctrine, administrative order, and missionary work.
In American Lutheranism, the word synod has two distinct organizational applications. First, it can designate an entire national denomination, such as the Lutheran Churc—issouri Synod (LCMS) or the Wisconsin Evangelical Lutheran Synod (WELS). Second, within the Evangelical Lutheran Church in America (ELCA), the term refers to the sixty-five regional geographic districts that make up the national church, each overseen by an elected synodical bishop. This representative model balances regional supervision with congregational voice, reflecting an ecclesiastical heritage rooted in the Reformation. Study how these structures developed in our overview of the history of the Lutheran Church and the initial protests of Martin Luther and the 95 Theses.
Evangelical Lutheran Church in America (ELCA)
Formed on January 1, 1988, through the merger of the American Lutheran Church, the Lutheran Church in America, and the Association of Evangelical Lutheran Churches, the ELCA is the largest Lutheran body in the United States. Headquartered in Chicago, Illinois, it represents approximately 3 million baptized members across more than 8,600 congregations, according to Pew Research Center (2021). The denomination is governed by a triennial Churchwide Assembly, a Church Council, and an elected Presiding Bishop.
The ELCA is a mainline Protestant denomination known for theological diversity, social justice advocacy, and progressive social positions. It approaches Scripture through historical-critical methodology, viewing the Bible as the inspired witness to God's revelation rather than a collection of inerrant scientific or historical propositions. The ELCA ordains women as pastors and bishops, a practice inherited from predecessor bodies that began ordaining female clergy in 1970. In 2009, the ELCA Churchwide Assembly voted to permit the ordination of individuals in monogamous, same-sex relationships and authorized pastors to bless same-sex unions.
The ELCA also prioritizes ecumenical relationships. It practices open communion, welcoming all baptized Christians to the Lord's Table, and has entered full-communion partnerships with six major Protestant denominations: the Episcopal Church, the Presbyterian Church (USA), the United Church of Christ, the Reformed Church in America, the Moravian Church, and the United Methodist Church. Furthermore, the ELCA operates twenty-six prestigious colleges and universitie—ncluding St. Olaf, Augustana, and Muhlenber—nd seven theological seminaries.
The Lutheran Churc—issouri Synod (LCMS)
Organized in Chicago in 1847 by Saxon German immigrants under the theological leadership of Carl Ferdinand Wilhelm Walther, the Lutheran Churc—issouri Synod is the second-largest Lutheran denomination in the United States, counting roughly 1.8 million members and nearly 6,000 congregations. Headquartered in Kirkwood, Missouri, the LCMS is an evangelical, confessional church body divided into thirty-five regional districts, each led by an elected district president.
The LCMS requires an unconditional subscription (*quia*) to the 1580 Book of Concord because it agrees entirely with Holy Scripture. The synod upholds the verbal inspiration and inerrancy of the Bible, rejecting theological liberalism and historical-critical revisionism. Consequently, the LCMS restricts the pastoral office strictly to men, citing apostolic instructions in 1 Timothy 2 and 1 Corinthians 14. It affirms marriage exclusively as the lifelong union of one man and one woman.
In sacramental practice, the LCMS exercises closed communion (also called confessional fellowship). Communicants are expected to be catechized and in full doctrinal agreement with the synod before receiving the Lord's Supper at an LCMS altar. The synod operates Concordia Seminary in St. Louis, Concordia Theological Seminary in Fort Wayne, Indiana, and an extensive parochial school network.

Wisconsin Evangelical Lutheran Synod (WELS)
Founded in Milwaukee in 1850 by German missionaries, the Wisconsin Evangelical Lutheran Synod is the third-largest Lutheran body in America, representing roughly 350,000 members and 1,250 congregations. Headquartered in Waukesha, Wisconsin, WELS is an exceptionally conservative confessional synod.
WELS shares the LCMS's commitment to biblical inerrancy and strict confessional subscription, but it carries these convictions further in ecclesiastical practice. WELS maintains that biblical principles of male spiritual headship prohibit women from holding the pastoral office and from casting votes in congregational business meetings. Furthermore, WELS enforces strict fellowship standards based on Romans 16:17. It avoids joint prayer, ecumenical worship services, or combined charitable projects with any Christian organization not in full doctrinal agreement. In 1961, WELS formally severed fellowship ties with the LCMS after concluding that the Missouri Synod had grown lax in its fellowship practices.
To preserve its confessional heritage, WELS operates the fourth-largest private Christian school system in the United States, supporting hundreds of Lutheran elementary day schools, area Lutheran high schools, Martin Luther College in New Ulm, Minnesota, and Wisconsin Lutheran Seminary in Mequon, Wisconsin.
Moderate and traditionalist alternatives: LCMC, NALC, ELS, and AFLC
Outside of the three major bodies, several smaller Lutheran synods and associations provide distinct theological homes for congregations seeking alternatives to both the mainline ELCA and the strict episcopacy of older synods:
- Lutheran Congregations in Mission for Christ (LCMC): Formed in 2001 by congregations departing the ELCA over ecumenical compromises and centralized authority. LCMC operates not as a traditional hierarchical synod, but as an association of independent congregations. It boasts more than 700 American congregations, emphasizing local congregational freedom and global church planting. Member churches hold traditional views on marriage while deciding independently whether to call female pastors.
- North American Lutheran Church (NALC): Established in August 2010 following the ELCA's 2009 decisions on human sexuality. The NALC encompasses roughly 400 congregations committed to traditional biblical authority, orthodox moral teaching, and active evangelism. Unlike the LCMS, the NALC affirms and practices the ordination of women to the pastoral ministry.
- Evangelical Lutheran Synod (ELS): Organized in 1918 by Norwegian Americans who refused to join the broad Norwegian Lutheran Church merger, tracing its roots to the historic 1853 Norwegian Synod. Often referred to as the "Little Norwegian Synod," the ELS maintains complete altar and pulpit fellowship with WELS, sharing its conservative confessional standards across approximately 130 congregations.
- Association of Free Lutheran Congregations (AFLC): Established in 1962 by Lutheran Free Church congregations that rejected union with The American Lutheran Church. Representing roughly 250 congregations, the AFLC emphasizes personal conversion, Pietist revival piety, and complete local congregational autonomy without centralized ecclesiastical oversight.
Comparing types of Lutheran churches: Key differences
To distinguish among the major different Lutheran denominations active across America today, examine how their core teachings and practices compare:
| Synod | US Membership | Biblical Hermeneutic | Women's Ordination | Communion Practice | Ecumenical Fellowship |
|---|---|---|---|---|---|
| ELCA | ~3.0 million | Historical-Critical | Yes (pastors & bishops) | Open Table | Full Communion with 6 denominations |
| LCMS | ~1.8 million | Biblical Inerrancy | No (men only) | Closed Communion | Confessional fellowship only |
| WELS | ~350,000 | Biblical Inerrancy | No (men only, no voting) | Closed Communion | Strict doctrinal agreement only |
| LCMC | ~300,000 | Authoritative Word | Congregational Choice | Congregational Choice | Independent association |
| NALC | ~140,000 | Classical Orthodoxy | Yes (pastors & bishops) | Pastoral Discretion | Orthodox ecumenical partnerships |
| ELS | ~19,000 | Biblical Inerrancy | No (men only) | Closed Communion | Fellowship with WELS only |
| AFLC | ~45,000 | Biblical Inerrancy | No (men only) | Congregational Choice | Autonomous local congregations |
In addition to theology, pastoral calling procedures vary widely across these synods. In the ELCA, congregations work closely with synodical bishops to interview candidates from an approved roster. In the LCMS and WELS, calling congregations consult district presidents who provide a list of qualified candidates, but the local congregation retains the divine right to issue the call. In the LCMC and AFLC, congregations possess complete autonomous authority to call any pastor who meets their standards.
Finding a Lutheran synod church in your area
Because each synod possesses a distinct worship culture and theological identity, prospective visitors are encouraged to learn which body a local congregation belongs to. ELCA churches typically offer formal liturgical services alongside contemporary alternatives, welcoming visitors of all backgrounds. LCMS and WELS parishes place central emphasis on traditional hymnody, liturgical forms, and doctrinal instruction.
Lutheran congregations are especially numerous across the Upper Midwest; explore regional patterns in our analysis of Lutherans in the Upper Midwest and see state data in Lutheran churches by state.
