It appears that there is a clear line of division on that issue with significant numbers of people and churches asserting that they are the only true church, with the other group taking the view that the "church of Christ" encompasses all believers and church bodies which hold to the essentials of the faith.
When it comes to any institution, any one of the models of institutions and denominations, it really matters not at all which among them lays claim to being the "only true church". The bottom line is that any and all doctrines that do not align with the Bible are either man-made, false.....or both. That's the beauty of having what is written because Jesus defeated Satan in the wilderness ONLY with, "It is written...," and He did not defer to anything outside what He, God, inspired to be written. In addition to that, we have what is written in 1 John 2:
[26-27 KJV] 26 These [things] have I written unto you concerning them that seduce you. 27 But the anointing which ye have received of him abideth
in you, and
ye need not that any man teach you: but as the same anointing teacheth you of
all things,
and is truth,
and is no lie, and even as it hath taught you, ye shall abide in him.
So, we are not limited to mere translations, but also possess the Spirit of God to instruct us that we may know the REAL Truth. Priests, pastors, teachers, et al, they ALL can teach errors. They ALL are fallible, and I do mean ALL, no matter what title/office may be attributed to him/them by men claiming that such came from upon high.
Jesus said of Himself:
[Jhn 10:11, 14 KJV] 11 I am
the good shepherd (singular):
the good shepherd (singular) giveth
his life for the sheep. ... 14 I am
the good shepherd (singular again), and know my [sheep], and am known of mine.
To those who are mature in the faith, all other voices are nothing more than voices piled upon voices into a roar of noise. In that storm, there is that still, small voice with that ring of the Divine, and that voice does not emanate from any earthly man, even though there are those who would claim he is speaking for God. God has already spoken, and needs no repeating, nor does the Lord give new revelation to any man.
I have that on good authority:
[Mal 3:6 KJV] 6 For I [am] the LORD, I change not;...
The enemy is therefore defeated only by what is written (past tense), not what will be written, or what is being written right now by those who presume to speak for God.
