Why is there no single, universally understood definition of "true Christianity"?

salaams.

i think that John 13:34-35 answers your question very well.

you are mistaken.

bismillah.

John 13:34-35

New International Version (NIV)

34 “A new command I give you: Love one another. As I have loved you, so you must love one another. 35 By this everyone will know that you are my disciples, if you love one another.”

true definition of a Christian inshallah.

[x](1 Peter 5:14)

Understood Definition

At the beginning it was considered a cult by the Romans.

From the very beginning it split into different groups with significant differences.

Maybe yes, it may be a false religion after all...

It's generally understood that christians are people who believe in Christ, and that he was the son of God, hence the name. From there, their beliefs vary widely due to different interpretations of the Bible, but they are all generally Christians, in being rooted in one central belief that Jesus Christ came to save the world and is the one way to heaven.

All religions including Christianity are false. The teaching of Jesus is true.

Yeah true christianism is all about mass control and profitting out their adherents superstition. and this is true for all forms of christianity

christianity is satan's greatest deception.

the messiah came to fix the hebrew faith. not create a lawless religion called cristos insanity

Religion is an expression of a person's faith. God is absolute; people, on the other hand, are fallible.

Peace be with you.

Of course.

Isn't that obvious?

Of course...individual xians get around that by each and every one of them thinking that "their" version of xianity is the only "true" one....but that's how delusions work.

Just about every Christian has their own personal set of beliefs.
