Can you clap with one hand?
Your statement is quite incomplete. (Especially if your absolute claim here supposedly applies to Christianity)
While religions are indeed often dependent upon trusting what their leaders have simply told them about certain realities (the one hand)...Christianity has never claimed to be only that.
In fact, if you read 1 Corinthians 15 from the apostle Paul very carefully, he says that if Christ, the Son of God, didn't rise from the dead (after becoming a man)...then our faith is empty. It's in vain. It's useless.
That means that the Christian faith rises or dies on the reality that a certain event took place...an event that if the Jerusalem Times had been in existence on the day of Christ's resurrection, it would have been banner headline news. No such historical event, no Christian faith -- no matter how much faith somebody exerts!
Therefore, it's more than faith (the one hand). It's also historical reality (the other hand).
If you take away key historical events of many or even most religions, it wouldn't really effect a lot of their key teachings. That's not true of Christianity. If you take away the death and resurrection of Christ, the apostle Paul said in 1 Cor. 15 we're to be pitied among all men.
How DARE you contradict what I heard on OPRAH!
