True Christianity is one wherein the Christian believes that he is saved for eternal life by the work that Jesus did on the cross, and by His resurrection.
It might be difficult for a Muslim or a Hindu or a Buddhist who believes in Jesus this way. But if they believe in Jesus for salvation, they are true Christians.
Conversely, anybody who thinks he is a Christian, but doesn't believe in Jesus' salvation, is not really a Christian.
The world likes to lump all the people who say they are Christians together, no matter what they believe. But true Christianity doesn't work that way.
