There is, it is called reason. Religions cannot be objectively right or wrong if they emanate from a specific set of circumstance which Christianity like all others did.
You are digging the hole even deeper. This is the most perfect archetype of a genetic fallacy I have ever seen. The origin of a belief has nothing to do with it's accuracy. If I read that that I had cancer on the back of a cereal box it would or would not be true independent of where I read it. As some of the greatest experts on testimony and evidence have said, Christianity sprung from exactly the place where you would have expected to find theological truth (that includes it's texts). I am not sure if a claim can be more wrong in every way than the one you made. It is text book wrong.
No one can say Hinduism is objectively right because Hinduism started in India and is not known to anyone. Politics, religion and social organizations are all alike and neither can be objectively right nor wrong.
No one has the capacity to know if it is right or wrong. I believe it is wrong but your the one who claims to know. BTW claims to knowledge have all the burdens. You claimed Christianity can't be true. Prove it. I do not think a statement can be any more arrogant than this one. I do not think Islam is true, I would never claim it couldn't be.
Psychotic people claim to know that a demonic bunny is chasing them. People can "know" anything they wish.
Amazing. You use a statement where people did not know something, to prove people can't know something, which was the opposite of your original claim that you do know something.
I can claim what I said above because you just said "every Christian". You are stating that Christianity's truth is subjective to the already indoctrinated believer.
I have no idea what that meant. Truth is not subjective to anything except truth. Murder doe snot become right or wrong because a Christian read it in the Bible. It was written in the Bible because it was true.
You seem to be contradicting yourself here. Christianity is only objectively true when confirmed by the Christian community. Christianity to many is objectively false and wrong amongst the other half of the opposing community.
It is really bad when you have to mangle another's words to make a point. I never said anything about anything being true based on who believes it. I said the following:
1. You have no way to know what you claimed even if it was true. It is not necessarily wrong, you can't possibly know it is true.
2. I said Christianity can be perfectly objectively true. I did not say it is known (in general to be).
3. I never said or thought that Christianity's truth has any dependence on a Christians faith. It is not true because anyone believes it. It can be true even if no one believes.
I do not believe you even understand what it is your saying. I will give it one more shot, it is your burden. Prove Christianity can't possibly be objectively true.
