This article from the Remnant Newspaper is excellent.

An excerpt.

We who are here together and in peace believe and hope in a fraternal world. We desire that men and women of different religions may everywhere gather and promote harmony, especially where there is conflict. Our future consists in living together. For this reason we are called to free ourselves from the heavy burdens of distrust, fundamentalism and hate. Believers should be artisans of peace in their prayers to God and in their actions for humanity! As religious leaders, we are duty bound to be strong bridges of dialogue, creative mediators of peace.  – Pope Francis, World Day of Prayer for Peace. Assisi, September 20, 2016

As notes, “Among the bizarre principles of bergoglian philosophy is this nugget: “unity is greater than conflict”. The consequences of this pseudo-principle are explained in Evangelii Gaudium, which claims to indicate the direction of Francis’ pontificate: we find expressions like “communion amid disagreement”, “friendship in society”, “multifaceted unity” and many others that, although deliberately ambiguous as Francis’ ideas and gestures have always been, nonetheless still permit an attentive observer to discern their true meaning.

En passant, it is noteworthy that someone who tries to appear as perfectly accessible to all – as a pastor who uses a telephone in order to reply to those who write to him, who devotes more time to greetings than to instruction when he meets pilgrims – prefers to keep one of the primary aspects of his doctrine shrouded in a nebulous mystery…. For what reason?

We have our own theory as to why that is, having everything to do with the great apostasy infecting the Catholic Church under this most disastrous pontificate. But rather than delve into the obvious contradictions, let us simply juxtapose the words of Pope Francis with those of the great Louis-Édouard-François-Desiré Pie, also knowns, simply, as Cardinal Pie—the French Catholic bishop of Poitiers–famous for his massive defence of the social reign of Christ the King. As the Catholic voice of Cardinal Pie answers the myriad errors of Pope Francis, let us pray for his intercession on behalf of our beloved Church in unprecedented crisis.

And as for our Protestant friends, let us recall that Christian can only be understood as Catholic. As St. Thomas says, we only call the “separated brethren” or the heretics and schismatics “Christian” out of politeness. They are not “Christian” simpliciter loquendo, but only in a qualified sense, secundum quid. So Christian unity can only be accomplished, as Pope Pius XI teaches in Mortalium Animos, by a return to the fold, to the one holy Catholic and apostolic Church–a prescription Pope Francis seems to reject. Again, contrast the words of Pope Francis at Assisi 2016 with those of his predecessor, Pope Pius XI:

So, Venerable Brethren, it is clear why this Apostolic See has never allowed its subjects to take part in the assemblies of non-Catholics: for the union of Christians can only be promoted by promoting the return to the one true Church of Christ of those who are separated from it, for in the past they have unhappily left it.
