By definition, all Christians are evangelicals. The word evangelical is derived from the Greek evangelion, which means “good news” or “gospel.” But the term evangelical has generally come to mean Protestants who emphasize personal conversion; evangelism; the authority, primacy — and, usually — inerrancy of the Bible; and the belief that Jesus’ death reconciled God and humans. Evangelicals tend to be conservative theologically, but the terms evangelical and conservative Christian are not synonymous, though they both may apply to the same people. Fundamentalists, who generally separate themselves from what they see as a sinful culture, are distinct from evangelicals, who tend to embrace culture and use it to build up the church. In the early 21st century, religious identification surveys show that between a quarter and 40 percent of the U.S. population claims the evangelical label. Many, though not all, also identify with a specific tradition or denomination, ranging from mainline Protestant denominations to the Roman Catholic Church. In Europe, evangelical is a generic word for Protestants. Uppercase only when part of a formal name.
