In The Old Evangelization, Eric Sammons critiques modern evangelization trends that mix pop psychology and marketing but fail to produce lasting results. As a diocesan director of evangelization, he turned to Jesus as the ultimate model for spreading the gospel. The book examines Jesus’ key encounters, such as with the Samaritan woman and the rich young man, drawing lessons on effective evangelization. Sammons also highlights how saints applied these principles and provides practical guidance for modern disciples. Emphasizing that evangelization is Christ’s command (Matt. 28:19-20), the book encourages believers to follow Jesus’ timeless approach.
