Holy Saturday" and "Christ's descent into Hell", particularly as outlined in the last volume of the book Theo-Drama, is still very heated. Following the magisterial principle expressed by the Fathers of the Church according to which "that what has not been taken up by Christ is not made whole" (Gregory of Nazianzus in Epistle 101: "For that which He has not assumed He has not healed", Latin: quod non est assumptum non est sanatum or quod non assumpsit, non redemit), then the redemption would be complete not with his death on the cross but only with the katabasis of his descensio ad inferos. Joseph Ratzinger called Theo-Drama a "profound analysis of the essence of Christian hope" and a "foundational contribution" to the theological field of eschatology. This theme is also explored in von Balthasar's 1969 book Theologie der drei Tage (Mysterium Paschale). Reception Pope Benedict XVI has described von Balthasar and Henri de Lubac as the two theologians he appreciates the most. In a 2016 interview, he claimed he shared an "inward intention" and "vision" with Balthasar, remarking positively, "It is unbelievable what this person has written and done." Balthasar's dramatic theory in Theo-Drama influenced the work of Raymund Schwager. Balthasar's major writings have been translated into English, and the journal he co-founded with Henri de Lubac, Karl Lehmann, and Joseph Ratzinger, Communio, currently appears in 12 languages. In delivering his eulogy, Ratzinger, quoting de Lubac, called Balthasar "perhaps the most cultured man of our time". In March 2018, together with Adrienne von Speyr, the Roman Catholic Diocese of Chur formally opened their cause towards canonisation. Von Balthasar has also been highly influential in the work of Bishop Robert Barron, who has been an ardent advocate of von Balthasar's soteriology.
