Title:
United_Methodist_Church

Context:
Wesleyan theology stands at a unique cross-roads between evangelical and sacramental, between liturgical and charismatic, and between Anglo-Catholic and Reformed theology and practice. It has been characterized as Arminian theology with an emphasis on the work of the Holy Spirit to bring holiness into the life of the participating believer. The United Methodist Church believes in prima scriptura, seeing the Holy Bible as the primary authority in the Church and using sacred tradition, reason, and experience to interpret it, with the aid of the Holy Spirit (see Wesleyan Quadrilateral). Therefore, according to The Book of Discipline, United Methodist theology is at once "catholic, evangelical, and reformed." Today, the UMC is generally considered one of the more moderate and tolerant denominations with respect to race, gender, and ideology, though the denomination itself actually includes a very wide spectrum of attitudes. Comparatively, the UMC stands to the right of liberal and progressive Protestant groups such as the United Church of Christ and the Episcopal Church on certain issues (especially regarding sexuality), but to the left of historically conservative evangelical traditions such as the Southern Baptists and Pentecostalism, in regard to theological matters such as social justice and Biblical interpretation. However, it should be noted that the UMC is made up of a broad diversity of thought, and so there are many clergy and laity within the UMC that hold differing viewpoints on such theological matters.
