To form a one world religion, you have to demolish the walls and build bridges with all schisms, denominations and sects. This is called ecumenism and it has been a project of the Roman Catholic Church since Vatican II in 1962. Ecumenism, from the Greek word “oikoumene,”carries the meaning “the whole inhabited world..." According to Wikipedia, "the Roman Catholic Church believes that having many different churches "openly contradicts the will of Christ, scandalizes the world, and damages the holy cause of preaching the Gospel to every creature."
Sounds impressive but the entire statement is built on a false premise. The word "Church" is a translation of the Greek word "Ekklesia" which simply means assembly. Calling the assembly of God's saints a church then has the connotation of some official administrative structure, an edifice or a building or an authority rather than an assembly of two or three people with Christ in the midst as He promised in Mat 18:20.
The Roman Catholics have single handedly twisted the meaning of the term assembly of the saints by turning it into an inanimate object called a building or structure labeled as a church. This church then exists like a strawman in a corporation with a life of its own and only man to thank for its existence. In the image of man it then becomes an officially sanctioned meeting place licensed by the state as a non-profit organization that doesn't have to pay taxes. Then they put their own distinctions on it, like no Jews allowed, worship Mary and Jesus alike. Accept "infallible" leadership and on and on it goes.
If I were to be strict about this, I would say that Messiah gave the perfect example when he addressed the assemblies that existed in Asia Minor. They were known as the assembly of their city in Revelation chapters 2 and 3. Yet one assembly promoted itself to exclusivity and then went on a centuries long murder spree of their competition to claim supremacy by attrition. What a shame.
Here is what the Bible says in Habukkuk 2:4 on salvation by grace, "Behold, his soul which is lifted up is not upright in him: but the just shall live by his faith."
Paul in Ephesians 2:8-9 wrote, "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast."
But didn't James, the Lord's half-brother say, "But wilt thou know, O vain man, that faith without works is dead?" In James 2:20?
The key to what brother James is saying is VANITY.
You see, Believers are baptized in the Holy Spirit. A person baptized and under the influence of the Holy Spirit is: #1, saved. #2, their expression of faith will include inspired works of faith. Not some church project to fund the building of a hospital to show off your faith with your name on a brick or some such nonsense. It is something that the Holy Spirit led you to do that you did in humility. The Messiah noticed. That's faith with inspired works in obedience to the Messiah otherwise it is vain works. Otherwise these are the people the Messiah prophecied about, "Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity."
Thus the "reformed" churches along with the Methodists and Lutherans have been officially taken prisoner by this agreement to end division.
The Roman Catholic Church didn't change. They didn't give up their position on salvation by grace and works. The Protestants gave it up. They gave up this precious distinction of the inspiration of works and accepted the "Hey, look at me" type or vanity of works.
Now that this issue is said to be settled, there are 94 more of Martin Luther's theses of protest yet to be tended to. You should read them. The 95 Theses of Martin Luther from Wittenberg.
I am hopeful it will take 500 years for each one of them to be debated and a result agreed upon.
By then the Messiah should be firmly in power.
