Again, this just shows your spiritual ignorance. There is a great difference. The Holy Spirit is the same regardless of whom "has" Him. The Holy Spirit could not and would not disagree with himself.
Then why so many different denominations, with their own set of beliefs based on the same set of writings?
Well praise the LORD, you finally see my point! Denominationalism is 100% wrong. (The Bible even says so in Revelations.) Matter of fact, when God says "Behold I stand at the door and knock..." in Revelations, he's not speaking (in every case) about a person's heart. He's speaking to us in the Ladiocean church age and how we've kicked Him out of church.
The MANY denominations began during the Nicene Council when the "Church" was set up. Constantine (I think was his name) decided to split God into three person in order to have Christianity fit in better with Roman/Greek religion. When he did that, it began the Catholic Church (The Harlot spoken of in Revelations, and she is a harlot because she has sold herself out and left the Word.) from that, all the other denominations split and divided because they didn't agree with what went on before. There were many reformers, like Luther or Wesley, etc.. that tried to straighten things out, but then the people, once they left the scene, "organized" religion again and fell away from the Word.
So, if you have three different denominations (or people for that matter) all disagreeing with each other on what the Word says, then either two are right and one is wrong or all three are wrong because the Holy Spirit would not disagree with Himself! You must stick with the Word regardless what "man" says.
Now, before you go and say that maybe what they did at Nicea was correct, let me just say this... The Nicene Council occurred approximately 250-300 years after Christ and his Disciples had left the scene.... How would they know better what was meant to be than the men who walked and talked with Christ Himself?
Check this out... Peter and Paul both went into the wilderness at separate times, alone. I can't remember how long each one stayed in the wilderness, but the point is that when they came out, they were both preaching the SAME word and this of course was before we had the NT. They both (obviously) had the Holy Ghost and both agreed with what the other preached even before they knew it...
Now, does this mean that there is not anyone in a denominational church with the Holy Ghost? No, but I'm talking about as a whole. Which I've said before God doesn't deal with groups, He deals with individuals. Anyway, you can't even get (for instance) all the Baptists that attend the same church to agree on the Word! (Insert Smiley pulling own hair out here)
This is why I don't claim any "religion" and why you will never find my name on any book or roll of any church. The church I attend officially has NO members... And remember, the Bride and the Church are two different things. One will be found with oil in their lamps and the other will not. One will be spotless and ready for the marriage with Christ, the other is a foolish virgin....
Which then refers you back to the types and shadows in the old testament and the levitical laws. (Like the one with not wearing garments made from two different materials is a type of not mixing the word with doctrine)
Anyway, that's how I explain the many denominations. Hope this helps!
