Religious expansionism

In Christianity, evangelism (or witnessing) is the act of preaching the gospel with the intention of sharing 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. In addition, Christian groups who encourage evangelism are sometimes known as evangelistic or evangelist.

The actions of Christians continue to lead to complaints by Muslims and Jews that, despite denials, their faiths are targeted by over-enthusiastic evangelists who tend to promote distorted image of such faiths. In eastern Europe in 1992, Orthodox Christians complained of a ruthless campaign by Roman Catholics to convert their members.
Evangelistic crusades, especially in other cultures, have been based on an attitude of arrogance, aggression, and negativism. These have obscured the gospel and caricatured Christianity as an aggressive and militant religion.
