"The Radical Christianity of the Gospels." Father Hugo writes a complete history of the retreat, beginning with his education at seminary in the 1930's (and the general mode of educating priests at this time), the life-changing nature of the retreat he made under Father Onesimus Lacouture in 1939, the reasons the retreat was so spiritually efficacious, the reasons opposition arose against it, and the arguments refuting that opposition.
