Kirchenzucht
Day's commitment to Church discipline is illustrated by an encounter with Fr. Daniel Berrigan, S.J., while on a Catholic Worker farm in New York. Berrigan was about to celebrate Mass for the community vested only in a stole. Day insisted that he put on the proper vestments before he began. When Berrigan complained about the law regarding liturgical vesture, Day responded, "On this farm, we obey the laws of the Church." He relented and celebrated the Mass fully vested.
