The principle or aim of promoting unity among the world's Christian Churches.
I do not see how that could ever exist, considering how the Bible is so scrambled by many religionists. It seems the only way for "unity of the faith" as God ordains, is to have our 'Bible-Only' as a prinicipal: "all the counsel of God" and "rightly dividing the Word of Truth", as God says. Additions by many innovators down to the present in man's religious ways, is unacceptable to God, I am sure (see John 17:11, 21-23; Acts 15:23; Rom. 12:4-5; 1 Cor. 12:25-27; 1 Cor. 16:19-20; etc. There are such Assembly fellowships in the world today, going on together as Bible-only; but also sadly various sects with various ideas; ignoring the "priesthood of all saints". One might see more about this in contacting Bible Truth Publishers, Addison, Il --USA. They have many books on such.
It is essential that one see the difference between the Old Testament religion for Israel, and the New Testament in the Church universal (meaning 'called out company of God' --"one body"). It shows readers today the promised coming of the Jewish Messiah: "Jesus -the Christ of God"; and having come, and the pleading to the Roman soldiers to kill him by the rebelious Israelites at that time (ignoring their Prophets --like Isaiah), Israel was then set aside by God (and has suffered much since, though preserved as yet God's people for a later time on the "new earth" --yet to be seen). Remember as shown in our Bible, what God says; that Israel will be restored as an earthly people AFTER the universal Church in Jesus -"the Christ of God", is 'raptured' (lifted up in joy) to Heaven as the "bride of Christ" (see also Rev. 7 about the 144,000 to be the NEW Israel on earth for a time. Until then, when the King --our Savior Jesus, comes with His "bride" --the Church: the Millennium, and reigns as He intented the first time, we NEED to follow His "Word of Truth".
So, let us seek to be "of one mind"; "rightly dividing the Word of truth" as our Creator-God says regarding His "..beloved Son": Jesus the Christ of God. We "must be born again" as John 3; John 14; Rom. 8; etc. declares. Now, we MUST be of "one accord" --not with various innovative denominated sects. If some are doing this in the world, let us all get on board to be "of one accord" and please our God. One can write to the site at holdingforth 1 @hotmail.com to look further into this.
