Evangelicalism (evangelical Christianity) is a branch of Protestant Christianity characterized by an emphasis on the authority of the Bible, a relationship with Jesus Christ, and conversion. Evangelical Christians tend to be more conservative in their theology and social beliefs than other branches of Christianity.

Evangelicals take the Bible seriously and believe in Jesus Christ as Savior and Lord. The term “evangelical” comes from the Greek word euangelion, meaning “the good news” or the “gospel.” Thus, the evangelical faith focuses on the “good news” of salvation brought to sinners by Jesus Christ.

Pentecostalism refers to Christian denominations who prioritize the spirit and whose worship services may include speaking in tongues, faith healings, and other charismatic expressions. Evangelicalism today is a protean movement that includes Christians on both the left and right of the political spectrum.

Baptists form a major branch of evangelical Protestantism distinguished by baptizing only professing Christian believers (believer's baptism) and doing so by complete immersion.
