[1][2][4] The denomination has 129,015 members in 878 congregations and an average worship attendance of 219,000 people[5] in the United States and Canada with ministries on five continents.

The majority joined together, forming the Swedish Evangelical Mission Covenant of America (now ECC) on February 20, 1885, in Chicago, Illinois.

Early leaders and influences included Carl August Björk (1837–1916) Paul Petter Waldenström (1838–1917) and David Nyvall (1863–1946), among others.

They desired to create a voluntary "covenant of churches" that were committed to sharing the Gospel of Jesus, as well as provide means for ministerial training.

[needs independent confirmation] Annual meetings are held, to which delegates are sent by the congregations, reporting back to local churches.

A major ministry of the denomination includes senior living facilities and is supplemented through its Covenant Benevolent Institutions department.

Among the ECC retirement systems, The Samarkand and Covenant Shores are considered to be two of the top facilities in the United States.

[21] California has the largest number of members, but the highest rates of membership are in Minnesota, Alaska, Kansas, Nebraska, and Washington.

The resolution upholds "celibacy, the state of abstaining (outside of marriage) in singleness, and heterosexual relations as the Christian standard".

[28][needs independent confirmation] The ECC does allow ministers to exercise pastoral discretion by attending a same-sex marriage ceremony.

Delegates also surpassed a two-thirds supermajority in removing the ordination standing of two pastors who contravened the ECC's communally discerned position on human sexuality.
