Look,
@JonC, regardless of what verses I quote, you are going to disagree. So what's the point? We already know that we believe different gospels.
I was actually looking for a verse that stated what you believe.
For example, If I believe Jesus is the Atoning Sacrifice for our sins.
I can point to 1 Jn 2:2. You could interpret the word as "propitiation" znd another as "expiation".
But even though we might disagree we are going to God's Word.
I can do that with my understanding of Atonement. I may make a misinterpretation, but it would be of the actual Biblical text.
That is the kind of thing I was looking for - not what you think might be taught but is actually written because I believe the Bible actually teaches "what is written".
Men can say the Bible teaches anything. I think it is important to trust God's Word.
I also hold extra-biblical beliefs (I think we all do). But this is a foundational doctrines. I certainly would not lean on my extra-biblical briefs.
BUT yes, I absolutely agree with you that we hold different gospels. I can give you the gospel I hold and you can highlight it in your Bible (even if we disagree about interpretation). For your "gospel" one would have to write it down and past it in their Bible to find it there. The danger, obviously, is which gospel (your version or mine) is the power of God unto salvation?
As mine is actually God's Word and nit what men think is taught in the Bible, we all know what I have chosen. And we know what you have chosen as well. The thing is, for you to believe a false gospel all it takes is for men to have misunderstood what the Bible teaches. For me to be wrong God would have to be wrong.
I like my odds.
You can use the biblical standard with my belief as well. Fair is fair and I welcome correction.
The ultimate point is to determine if our beliefs (even when people disagree) are really in God's Word or if they are just theories men believe are taught by God's Word.
It is important because we are commanded to test doctrine and to lean on every word that comes from God rather than our own understanding.
Does a belief that merely represents what some Christians believe really matter if it cannot be tested against what is written in Scripture and pass that test????
