Evangelization is that process in the Christian religion which seeks to spread the Gospel and the knowledge of the Gospel throughout the world. It can be defined as so:
the announcement of the Good News of Jesus Christ in the power of the Holy Spirit with the goal of inviting all listeners to trust Him —Dr. Alvin A. Low, Touching Lives for Eternity (Effective Evangelism), published by Lulu.com, p. 10. In its precise sense, evangelization is the missio ad gentes directed to those who do not know Christ. In a wider sense, it is used to describe ordinary pastoral work, while the phrase “new evangelization” designates pastoral outreach to those who no longer practice the Christian faith. —CONGREGATION FOR THE DOCTRINE OF THE FAITH, Doctrinal Note on some aspects of Evangelization, 12, 2007
