From the Depths of Our Hearts is an unprecedented work by the Pope Emeritus and a Cardinal serving in the Vatican. As bishops, they write "in a spirit of filial obedience" to Pope Francis, who has said, "I think that celibacy is a gift for the Church... I don't agree with allowing optional celibacy, no."

Responding to calls for refashioning the priesthood, including proposals from the Amazonian Synod, two wise, spiritually astute pastors explain the biblical and spiritual role of the priesthood, celibacy, and genuine priestly ministry. Drawing on Vatican II, they present priestly celibacy as more than "a mere precept of ecclesiastical law". They insist that renewal of the Church is bound to a renewed understanding of priestly vocation as sharing in Jesus' priestly identity as Bridegroom of the Church.
