Evangelical Covenant Church
From the Evangelical Covenant Church website:
In 2005 it reported 775 churches in the U.S. with 1500 clergy and 118,000 full members. Founded in 1885 by Swedish immigrants, the ECC values the Bible as the Word of God, the gift of God's grace and ever-deepening spiritual life that comes through faith in Jesus Christ, the importance of extending God's love and compassion to a hurting world, and the strength that comes through unity within diversity."
It is the denomination of Life.church, the largest evangelical multi-site megachurch in the US with over 51,000 members at 32 campuses across 10 states.
