You can (or anybody else) call themselves a Christian. That does not mean you are one. The scripture is right. Christians are known by their fruit, their love for one another, and gradual progression toward Christ’s character.
If you doubt what I say, check out Matthew 7:21-23, then backup and read 7:1-21.
You strike me as someone trying to cause an issue, rather than find the truth.
It’s not ours to judge - it’s Jesus’s sole responsibility
So you know nothing about the fruits of the Holy Land Christians but choose to judge them anyway?
