“If you were to identify Catholic prophets in the twentieth century,” says Georgetown University professor Chester Gillis, Daniel Berrigan “would be right there with Dorothy Day or Thomas Merton.” His activism, adds Gillis, is “rooted in prayer. It is done out of the commitment to the Gospel. That differentiates it from all the other secular movements” Daniel Berrigan, SJ died on April 30, 2016. He was 94 years old.
