In John 15:1 (here in Bible Gateway) Jesus said that He is the true vine. The implication is, again obvious, there are vines that are false.
That begs at least one question, how do we identify false vines. The answer that could leap to mind is anyone that does not agree with our understanding of the Scripture. While that is an easy answer, it may not be the best, for it may be too narrow. I wonder if 1 John 4:2 – 3 (here in Bible Gateway) gives us some guidance on this.
Many different perspectives on the Scripture exist in the Body of Christ. Some positions that some communities take make it difficult if not impossible for me to regularly engage in those communities. But, should I consider them a false vine? If they confess that Jesus came in the flesh, according to John, they are from God. They are part of the larger Body of Christ.
I am still processing what to do with that.
