Are all religions truthful?
It is popular to claim that all religions are right.
When people say that all religions have the truth, they are either lying, misinformed, apathetic, or they have redefined the word truth. Let's look at each of these possibilities.
One form of this argument states, "all religions say essentially the same thing." If all religions essentially say the same thing, then there would be no need for multiple religions. When those religions come in proximity to one another, we should expect them to be able to seamlessly merge since they teach the same thing. Instead, we find conflict. That's because essentially they don't say the same thing. They are in opposition.
Often when someone claims that all religions have the truth, they have redefined the word "truth" to mean "practical value" and not, "propositions that correspond with reality." There are many things that have practical value but are wrong. Cleaning your house because you believe that Abraham Lincoln is going to visit you for tea has practical value (your house has been cleaned), but it is wrong.
Why would anyone redefine "truth" to mean "practical value," Society has prioritized, political peace, over possessing truth and therefore if a religion "works" in terms of offering political peace, then it is said to be "truthful" under this new definition. So, any religion that can coexist in proximity with others is generally considered to have practical value (we shall call this neo-truth.) However, if a religion is so radical that it disturbs the political peace, then it is unanimously claimed to be wrong.
Those that claim all religions are right, have prioritized avoiding conflict over the pursuit of truth. If the highest priority is to avoid conflict you can almost guarantee that the truth will not be reached between multiple parties. It is through conflict and debate that the truth is found out. Any judge or lawyer will tell you that the truth doesn't always come easily, but comes through hard-fought conflict.
Often, those who have prioritized avoiding conflict above the pursuit of truth claim that they have done so in the name of love. However, this is the least loving thing one can do. Only in an atheist world could a conflict-free society be more important than the pursuit of truth. Only in a world where God does not exist could it be more important to have political peace, than to know the truth. For the 95% of the world who believe that God exists, we don't have the luxury of being conflict-free in the world we now live. We must pursue truth, and that comes with conflict.
So, ultimately, saying all religions are right, is an atheist idea. Because if all religions are right, then all religions are simultaneously wrong. This is because, each religion, save a very few, claim to have the truth exclusively. The Muslims claim the Jews are wrong. The Jews claim the Christians are wrong. The Christians claim the Hindus are wrong. Etc. etc. etc. If all religions are right, at least on that point, then no religion is right. So to claim that all religions are right is as much an atheist thing to do as to claim they are all wrong.
Often people who claim all religions are right, have confused tolerance with agreement. Two religions that tolerate each other's observers in close proximity, can appear to an outside observer, to be in agreement. If we don't recognize a division between tolerance and agreement, then we will make the mistake of thinking that all religions agree.
Often people who claim all religions are right, they do so from a position of apathy. They simply don't care, and this is a pretty decent way to escape probing questions about religion. The honest thing to do is admit apathy, rather than make a logically impossible statement.
Even if all religions were right, Muhammad claimed to be a prophet, a person who speaks on behalf of God. Jesus claimed to be God in human form. Jesus is, therefore, greater than Muhammad (if all religions are right). Siddhartha Gotama, the founder of Buddhism, claimed to be a human who became enlightened, Jesus claimed to be God in human form. So Jesus is greater than Buddha (if all religions are right). In fact, this logic works for any religion lead by someone who claims to be less than God. Therefore, the most logical thing to do, if all religions are right, is to follow Jesus.
