To a point, I think you are right; however, we should still strive for it and not give up...
("to the crowd")
There can still be "unity of the faith" where folks disagree on such things as eschatology. Folks just need to be reasonable about where they draw the line in the sand and forbid any fellowship with anyone on the other side of that line.
My
faith is not in eschatology (It is just something I have spent a lot of time and focus studying.) - my
faith is in God/Jesus.
My
endeavor is to understand God's Truth by the Holy Spirit and promote its acceptance among believers and unbelievers alike.
And, yes - that is where
disunity can occur - when folks comprehend the 'detail' of "what scripture says" differently than others [do].
However, the
extent of disunity depends on the "just exactly how much someone needs to believe exactly as I do before I will have any fellowship with them" attitude that folks have sometimes.
I suggest that - in reality - there are "levels" of fellowship to be had - and that the level of fellowship that may be had is based on the willingness of folks to accept whatever is "common enough" between them and someone else.
A certain level of fellowship should always be had between born-again believers.
If that is all you have in common between you - celebrate the fact that both of you share a common believe in the Lord Jesus Christ.
The more you have in common - all the better!
The problem is that some folks are sometimes too insistent upon others being in full agreement with them about anything-and-everything before they will consider any reasonable level of fellowship with them at all.
This is a pride-based problem.
This is where [true] "unity of the faith" comes into being real - it is based on the "common faith" and "common salvation":
Jude 1:
3 Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.
Yes - there are things that matter (doctrine) that must be agreeable for really good fellowship to be had - such as in a local new testament church; however, in certain situations - like internet forums, for example - it is befitting that we be in agreement where the "common faith" and "common salvation" are concerned - and, not allow ourselves to bicker over things whereby the fellowship is broken or torn apart.
We should all "agree to disagree agreeably" - when/where necessary - for the sake of what might be accomplished if we stand together in the faith.
I suggest that most of the members of this site do not really understand or appreciate the real worth of having the ability to communicate with other Christians worldwide on this platform.
We should be ever aware of what possibilities exist to further the cause of Christ and utilize every forum on this site in the best way we can to do so.
What are we doing to minister to others?
And, yes - a certain amount of this does happen on CC - and, that is good. But, how can we "raise the bar"...?
How can we make this site a much happier place to visit rather than allowing it to become the dumping grounds of trolls and disgruntled people?
And, how do we do this with the proper attitude and encouragement of members of the site rather than depending, expecting, and relying upon hard-hammer action by the site staff?
Do we not all have to start with self?
How can we better use the forums that are constantly bad-mouthed as being the most useless

forums on CC?
While no doubt most of us visit one or more news outlet sites to gain a better understanding of what is going on in the world - let me tell you something - sometimes - the very first time I am made aware of "certain news stories" - it is in the CC news forum.
I find this to be worthwhile.
So - don't knock it - make it better.
What can
you do to make it better?
Each and every member has a part - let us all do our best to make sure we have done our best to make a positive difference...
