>>What usually happens is just what has happened among Protestants: divisions into new denominations or branches of denominations. They all claim the authority of the Bible and the inspiration of the Holy Spirit but cannot agree even on essentials, such has how one is saved, and if once saved, are they always saved?
Even if Protestants disagree, we all look to Jesus as the answer. If I am Calvinist and my friend is Arminian and we have significant differences on many theological issues, the article overlooks the fact that we both look to Christ and hear the counsel of the Holy Spirit. I do not think that Calvin saves me or condemns my friend. He does not think that Arminius or Wesley saves him or condemns me. So, our differences do not matter.
The Roman Catholic Church had splits before Luther. Some of them exist to this day in the Eastern Orthodox Churches. But most were crushed by the forces of the RC Church (or, more correctly, by secular armies of nations controlled by the Pope) so that their division would exist no more.
>>Protestants also have serious divisions regarding the moral issues of our time: abortion, same-sex unions, euthanasia, etc.
Yes we do. Its caused by people placing the things of this world above the things of the next. Sadly, Pope Francis is bringing those kinds of divisions to the RCC too.
Well, that’s certainly the Roman Catholic line. However we Orthodox have gotten on quite well since Rome went her way. Moving on...
The Catholic Church looks to Christ too. In fact the entire Mass is focused on Christ — The Liturgy of the Word and the Liturgy of the Eucharist.
That statement is simply not true.
Here are the statements of faith for several denominations or independent churches for anyone to peruse for themselves to see what kind of "divisions" there are within "Protestantism" (as the term is used by Catholics to describe anyone not Catholic).
