In Christianity, evangelism is the commitment to or act of publicly preaching (ministry) of the Gospel with the intention of spreading the message and teachings of Jesus Christ.
Christians who specialize in evangelism are often known as evangelists, whether they are in their home communities or living as missionaries in the field, although some Christian traditions refer to such people as missionaries in either case. Some Christian traditions consider evangelists to be in a leadership position; they may be found preaching to large meetings or in governance roles.
Christian groups who encourage evangelism are sometimes known as evangelistic or evangelist. The scriptures do not use the word evangelism, but evangelist is used in (the translations of) Acts 21:8, Ephesians 4:11, and 2 Timothy 4:5.
