The Church of the United Brethren in Christ (New Constitution) was a Protestant Christian denomination with Arminian theology, roots in the Mennonite and German Reformed communities, and close ties to Methodism that formed in 1889 by a majority of the Church of the United Brethren in Christ when that denomination (of a similar tradition) amended the church constitution to give local conferences proportional representation at the General Conference; to allow laymen to serve as delegates to General Conference; and to allow United Brethren members to hold membership in secret societies.
Led by Milton Wright, the only one of the church's six bishops to side with them, they reorganized under the original constitution as adopted in 1841.
Many of the former Evangelical United Brethren churches in Pennsylvania joined the new ECNA, even though their deeds belonged to the Methodists, prompting a ten-year dispute.
Eventually, the Methodists gave the dissenting Pennsylvania churches the opportunity to purchase their deeds for token amounts.
