In May 2019, Pope Francis issued Vos estis lux mundi [You Are the Light of the World], his motu proprio addressing sexual abuse. Teresa Kettelkamp, a member of the Pontifical Commission for the Protection of Minors, said that “we expect our bishops to be good shepherds. . . . When they don’t, Church credibility is lost. That’s where Vos Estis can play a redeeming role with respect to the Church.”
