Are all religions just different paths that all lead to the same God? Are they all equal? Is "true for me, but not for you" true? Is there such a thing as objective truth, or is it all subjective?
You say that I'm a raving lunatic? You think 1+1 really equals 2? Well who are you to impose your beliefs on me!? I believe that 1+1=3, and you have to respect my opinion! While 1+1 may equal 2 for you, for me it equals 3. We all have our own opinions, and nobody is more right than anyone else. Everyone's entitled to their own opinion, and we're all equally right.
Note the sarcasm here. When something's true, it's true for everyone, not just for those who know the truth. The same goes for all other truth. If I disagree with it, I'm wrong, period.
Think about it. Truth is the way things are, and our beliefs can't change the physical world. If I believe that roses are black, my belief won't change the fact that they aren't. We are not super-psychics; we can't change the world just by thinking something.
The only way that all religions can be equally true is if they are equally wrong. The different world religions are so hopelessly contradictory that nobody who accepts the objectivity of truth can accept religious pluralism.
Take Islam, Christianity, and Judaism, for example.
| Trinity? | Messiah? | Old Testament? | Mohammad? | Koran? | New Testament? | |
| Christianity | Yes | Yes | Yes | No | No | Yes |
| Islam | No | No | No | Yes | Yes | No |
| Judaism | No | No | Yes | No | No | No |
Just with these six beliefs, we can see that Christianity, Judaism, and Islam contradict each other. Either God is or isn't a Trinity; either Jesus is or isn't the Messiah; either Mohammad was or wasn't a prophet of God; etc., etc. We know that truth cannot contradict truth and that truth is true no matter what, at least two of these religions have to be wrong.
Now let's take the three previous religions (CJI) and compare them with Buddhism.
| Reincarnation? | God? | All suffering is from desire? | |
| CJI | No | Yes | No |
| Buddhism | Yes | No | Yes |
Just from these three issues (and they're important ones), we can see that Buddhism and the world's three largest monotheistic religions are worlds apart. Again, truth cannot contradict truth, so one of these two belief systems (I'm grouping the three monotheistic religions together just to make it easier to compare) has to be wrong. And since truth is true no matter what, you can't say that one's true for me and the other is true for you.
Now, I'm not saying that all religions except one are totally false. I do believe that all religions contain some truth, but all but one contain truth mixed with falsehood. Only one religion can contain nothing but truth, making it truer than every other religion.
Is premarital sex wrong? Is homosexuality wrong? Is murder wrong? Many people believe that things like murder and stealing are objectively wrong no matter what, but other things, like homosexuality and premarital sex, are subjective.
The problem with this type of subjectivism is that it's illogical. If there is a definite moral law that says "this, that, and the other thing are bad," then everyone must follow it. If the morality of an act is "subjective", then that means that it must be objectively not wrong. Every act is objectively wrong or not wrong, and if something is subjective, then that means that it's objectively not wrong. If there were an objective moral law that said it was wrong, then it would be objectively wrong, no matter what. If there is no objective law that says that it's wrong, then it's objectively not wrong. The subjectivity would come in when a person, for whatever reason, decides not to do it, even though it's okay to do. Unless one is going to argue that different people follow different moral laws (which is absurd), then no moral act can be truly subjective.
It must be stressed, however, that different opinions do not equal different moral laws. Various people or groups of people may have various OPINIONS about what the moral law says, but all but one will be wrong (assuming that one of them is right). Just like all truth, the moral law does not change because people believe one thing over another.
