Lutheran Church AND THE Synod Evangelical Lutheran Church
Martin Luther (/ˈluːθər/ or /ˈluːðər/; German: [ˈmaɐ̯ tiːn ˈlʊtɐ]; 10 November 1483 – 18 February 1546) was a German professor of theology, composer, priest, monk and a seminal figure in the Protestant Reformation. Luther came to reject several teachings and practices of the Late Medieval Catholic Church. He strongly disputed the claim that freedom from God's punishment for sin could be purchased with money. He proposed an academic discussion of the power and usefulness of indulgences in his Ninety-five Theses of 1517. His refusal to retract all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the Pope and condemnation as an outlaw by the Emperor.
Luther taught that salvation and subsequently eternal life is not earned by good deeds but is received only as a free gift of God's grace through faith in Jesus Christ as redeemer from sin. His theology challenged the authority and office of the Pope by teaching that the Bible is the only source of divinely revealed knowledge from God and opposed sacerdotalism by considering all baptized Christians to be a holy priesthood. Those who identify with these, and all of Luther's wider teachings, are called Lutherans even though Luther insisted on Christian or Evangelical as the only acceptable names for individuals who professed Christ.
The Lutheran Church–Missouri Synod (LCMS), often referred to simply as the Missouri Synod, is a traditional, confessional Lutheran denomination in the United States. With 2.1 million members, it is both the eighth-largest Protestant denomination and the second-largest Lutheran body in the U.S., the largest being Evangelical Lutheran Church in America. The LCMS was organized in 1847 at a meeting in Chicago, Illinois, as the German Evangelical Lutheran Synod of Missouri, Ohio, and Other States, a name which reflected the geographic locations of the founding congregations. The LCMS is headquartered in Kirkwood, Missouri.
The LCMS has congregations in all 50 U.S. states and two Canadian provinces, but over half of its members are located in the Midwest. It is a member of the International Lutheran Council, and is in altar and pulpit fellowship with most of that group's members. The LCMS is divided into 35 districts—33 of which are geographic and two (the English and the SELC) are non-geographic. The current president is the Rev. Matthew C. Harrison, who took office on September 1, 2010.
The SELC District is one of the 35 districts of the Lutheran Church–Missouri Synod (LCMS). It is one of the Synod's two non-geographical districts, along with the English District, and has its origins in the congregations of the former Slovak Evangelical Lutheran Church, which merged with the LCMS in 1971. The SELC had been formed in 1902 in Connellsville, Pennsylvania, and changed its name to the Synod of Evangelical Lutheran Churches in 1959 due to decreasing identification with the Slovak language and culture.
Spread over 11 U.S. states and the Canadian provinces of Ontario and Quebec, the great majority of congregations are in the Great Lakes and Mid-Atlantic regions. The district now includes approximately 52 congregations and missions (the fewest of any LCMS district), subdivided into 4 circuits, as well as 13 preschools and 4 elementary schools. Baptized membership in district congregations is over approximately 17,000. 
SELC District offices are located in Clark, New Jersey. Delegates from each congregation meet in convention every three years to elect the district president, vice presidents, circuit visitors, a board of directors, and other officers.
