Cardinal Robert Sarah has hit out at critics of Benedict XVI, accusing them of “vulgarity and baseness” in their responses to the former pope’s preface to the cardinal’s latest book.

“The arrogance, the violence of language, the disrespect and the inhuman contempt for Benedict XVI are diabolical and cover the Church with a mantle of sadness and shame,” Cardinal Sarah said. “These people demolish the Church and its profound nature.”

In a preface to Cardinal Sarah’s book The Power of Silence: Against the Dictatorship of Noise, Benedict XVI wrote that Pope Francis deserved praise for appointing Cardinal Sarah to oversee the Church’s liturgy.
