No Response to the Pope from Cardinal Sarah
I found an interesting German report here which suggests that Cardinal Sarah has failed to respond to Pope Francis' request to publicise his response to statements by the Cardinal on the Internet (as outlined in this post from October 23rd). The post suggests the deadline was discovered by research from Katholischen Nachrichten-Agentur (KNA) but I have not been able to verify this.
As the Dom Radio report states, Pope Francis decree "Magnum Principium" specified that the national episcopal conferences are responsible for the translation of liturgical texts. The moto proprio said episcopal conferences need only confirm these translations with Rome. So if there is there a concern about the change, no alternative translations should be written.
Cardinal Sarah, however, considers that the final decision should remain with Congregation for Divine Worship. At least that is the result of a post that Sarah let be published on the French Internet portal, L'Homme Nouveau. Several other portals took over this text or quoted excerpts from it.
Francis then addressed a letter to the Cardinal questioning Sarah's authorship, but at the same time urging him to promote the dissemination of "this, my answer" on the relevant websites, as well as to all episcopal conferences and members and advisers of his Dicastery".
L'Homme Nouveau editor-in-chief, Philippe Maxence confirmed, on request, that the text was indeed written by Cardinal Sarah himself. So far, the Cardinal has also made no denial. Also, no request was made to the editors to publish a reply from the Pope. "If I had received something like that, then I would have published it," says Maxence. The Congregation for Divine Worship and the Discipline of the Sacraments has not yet commented.
