Evangelism, Crusades and Inquisition are three terms that come to us from Christian history. Evangelism comes from the earliest phase of Christianity, and refers to 'the act of spreading the good word' used by Christ's followers to convert Greeks and Romans to their belief system based on the myths of God, Sin, Prophecy, Saviour and Redemption. This began 2,000 years ago. It eventually consolidated the Roman Empire by transforming it into the Holy Roman Empire 1,500 years ago.
