The Pope speaks tohis own people
It matters not a jot which other churches may or may not be offended by the truths as espoused by the Magisterium . What does matter is that the writings and utterances of Christ’s Vicar on Earth should be adhered to, by all the Prelates, Bishops, Priests and faithful throughout the Universal Church.
Ecumenism may suffer collateral damage from the friendly fire emanating from the Vatican but differences on the centrality of the Eucharist have been at issue between Anglicanism, Catholicism, and all the other isms for many a long year.
