27. Are all religions fundamentally the same?

No.

All religions are superficially the same and fundamentally different. World religions have more contradictory beliefs than complementary ones. The notion that all religions teach basically the same thing—that we ought to love one another—demonstrates a serious misunderstanding of world religions.

While most religions have some kind of similar moral code because God has implanted right and wrong on our consciences, they disagree on virtually every major issue, including the nature
of God, the nature of man, sin, salvation, heaven, hell, and creation! Think about it: the nature of God, the nature of man, sin, salvation, heaven, hell, and creation. Those are the biggies!

According to the law of non-contradiction, contradictory propositions cannot both be true at the same time and in the same sense. So, if one is true, rest are false. If one religion comesout to be true,rest has to be false as it's not logically possible forall religions to be true “at the same time and at the same time.”So, the statement “all religions are fundamentally the same” goes out of the window. Someone might say, “All religions have one final destination or all roads lead to the same God.” Well, this argument is illogical too. We have established that all religions have differentopinions on the fundamental doctrines. So, if a religion claimsthat reincarnation is true and if others reject this claim, we havea serious problem. How can both be true at the same time?Would the people in a particular religion who claimsreincarnation is true get another life on earth but the people in a
particular religion which claims there is only one life, gets no
chance to live again on this earth. Serious contradiction!
Again,

Different roads, different destinations. Every road doesn't leadyou to the truth. As we have discussed, almost all the religionsdiffer on major doctrines.Now, if there is a God, why would he create so many religionsin the first place? Why would he want all of humanity to fight
against each other for religions' sake? God doesn't need different identities of Him being revealed at different points of time by different groups of people.

If a God, being one, entered into this realm and interacted with human beings in different parts of the world using different names, out of all he would be deceiver of deceivers. He would be the one who brought in all this confusion among various religions. We know God wouldn’t deceive. I don't think a
supremely intelligent God would take such a step to show that He is The God.

As we have discussed earlier, truth is narrow and it is applicable to everyone and it doesn't rely on personal preferences. So, if God revealed Himself somewhere in history, that revelation alone would be true. Rest would be just man-made ideologiesthat he created to suit his personal preferences. God must have revealed Himself somewhere and the rest would be a counterfeit mimicking the original revelation. The existence of so many religions is not an argument against God’s existence or an argument that truth about God is not clear.

Rather, the existence of so many religions is demonstration of humanity’s rejection of the one true God. Mankind has replacedHim with gods that are more to their liking. This is a dangerous
enterprise. The desire to recreate God in our own image comes from the sin nature within us—a nature that will eventually "reap destruction” (Galatians 6:7-8).

So, we can rightly conclude that :

So, saying all religions are different paths to the same God is false if we logically look into the specifics of what each religion teaches.
