Evangelization

Evangelization is what Christians are called forth by Christ to do …

Then Jesus approached and said to them, “All power in heaven and on earth has been given to me. Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, until the end of the age.” [Matthew 28:18-20 http://www.vatican.va/archive/ENG0839/__PW1.HTM]
