How to "destroy" Church unity

It's a shame that we, as the Church, have to see a headline like this: "Giving bishops final word on Mass translations would ‘destroy’ Church unity: Cardinal Muller." 

As reported on by the Catholic Hearld, Cardinal Gerhard Müller made the following statement during an interview with Passauer Neue Presse (a German newspaper): "The ultimate authority in the case of doubt cannot lie with the Episcopal Conferences, which would destroy the unity of the Catholic Church in faith, confession and prayer." 

All faithful Catholics should agree with the Cardinal here. This is a serious matter, to be sure, considering the climate at the Vatican these days, but let us not forget the words of Jesus after St. Peter acknowledged Him as the Christ: 

Blessed art thou, Simon Bar-Jona: because flesh and blood hath not revealed it to thee, but my Father who is in heaven. And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. (Matt. 16:17-18)

Don't let news stories like this rattle your nerves. Have faith. Be obedient to the Magisterium. Pray.
