Evangelization is proclaiming the gospel of salvation in Jesus Christ to others. We evangelize using both our words and our actions. It's the most central mission of the Catholic Church and her deepest identity. It's also the calling of every intentional disciple of Christ.
“After this the Lord appointed seventy-two others and sent them on ahead of him,
two by two, into every town and place where he himself was about to go,
and he said to them, ‘The harvest is plentiful, but the laborers are few.”
Luke 10:1
