A particularly controversial doctrine in the Evangelical Churches is that of the prosperity theology, which spread in the 1970s and 1980s in the United States, mainly through by Pentecostals and charismatics televangelists. This doctrine is centered on the teaching of Christian faith as a means to enrich oneself financially and materially, through a "positive confession" and a contribution to Christian ministries. Promises of divine healing and prosperity are guaranteed in exchange for certain amounts of donations. Fidelity in the tithe would allow one to avoid the curses of God, the attacks of the devil and poverty. The offerings and the tithe occupies a lot of time in the worship services. Often associated with the tithe mandatory, this doctrine is sometimes compared to a religious business. In 2012, the National Council of Evangelicals of France published a document denouncing this doctrine, mentioning that prosperity was indeed possible for a believer, but that this theology taken to the extreme leads to materialism and to idolatry, which is not the purpose of the gospel. Pentecostal pastors adhering to prosperity theology have been criticized by journalists for their lavish lifestyle (luxury clothes, big houses, high end cars, private aircraft, etc.).
