The seven historic mainline Protestant denominations that once dominated American religious, cultural, and political life in the 19th and early 20th centuries. The group typically includes the United Methodist Church (UMC), Evangelical Lutheran Church in America (ELCA), Episcopal Church (TEC), Presbyterian Church USA (PCUSA), American Baptist Churches USA (ABCUSA), United Church of Christ (UCC), and Christian Church (Disciples of Christ).
These denominations no longer reflect the sounder beliefs and practices of their founders, particularly in regards to women clergy, abortion and LGBT affirmation.
