The simple answer is we cannot.
But I never liked simple.
There is one and only one correct faith.
That is the belief in the truth, whatever that truth is. Whether there is one God many gods or no gods. It may contain many beings we have no words for. It also includes some laws of physics that may not even be based on mathematics, it just happens that statistically, the results appear mathematical.
We do not know, but the truth is out there whatever it is and it is true.
So it is possible in fact it is unavoidable that there is one totally and utterly correct faith a belief in what is true.
The trouble is with our very limited experience and the impossibility of ever us observing the whole of the truth, it is very unlikely that any human has ever come close to having a way of knowing what is true.
So my next question is: when does a faith become a religion? Indeed can a faith be a religion?
Can you have a religion with no members?
If you can then there must one correct religion, with probably no members.
However, that is not the usual definition of a religion.
What is meant by "a religion"? To my mind, a religion is a political organisation of people to encourage people to meet and follow a faith which is usually written down in one or more documents.
(Often including beliefs about the number of divine beings there are and what their names are and why that matters to us and why it matters to them and how that affects how we should live. Although all of the above components are optional, so expanding on this list is a waste of space.)
Although one of my good friends claims to be a member of the dreadful spaghetti monster religion which is a religion I believe of one member. He does this basically because it does not tie him to a particular set of morals and he can make it up as he goes along.
An excellently simple religion and with very little risk of causing religious wars.
So in my understanding "a religion" is just a political organisation based around some doctrine. Which boils down to a political party of some sort.
Can a political organisation have the attribute of being wrong?
I would say no.
The political organisation is not wrong some of their ideas may be wrong.
Their doctrine unless they happen by pure luck happened to have stumbled on to the one true faith are likely to be wrong in several aspects of their faith.
But it does not mean that meeting to share that doctrine is wrong, it may be misguided but it is not logically wrong. Logic does not come into it.
We could found the Wrong religion. That has the Tenet. We must discuss and debate the fact that our understanding of the universe is wrong. Why it is wrong and discuss if there is anything we can do about it. It would be probably the best bet for us to find the one true religion as we might just happen to work out a few things that are undisputedly true, which would be a step in the right direction.
So there may be one Wrong religion if that is the political goal of the religion.
To a certain extent, whatever is believed will always be wrong because we are not omniscient.
However, to a certain extent, almost all religions have a lot of correct beliefs.
1. We are Human.
2. Life is a mystery.
3. We need a code of conduct to live by.
Even if we all bicker about the details.
I do not think you can say any religion is wrong. because political organisations can not be wrong. They may be broken; dysfunctional; unsuccessful; very successful but not wrong.
I think you could say the beliefs of a religion are wrong.
However, there are very few, bordering on the exceedingly probably non-existent, utterances made by any human about the whole of existence or even small parts of existence that are 100% accurate because we are not omniscient. There is a lot we just do not know so we make mistakes all the time.
So you can say that about almost any statement.
However, there is one sense that most of the well-known religions are right.
Most well-known religions and a few others have served their cultures for millennia.
They have been useful tools supporting community's needs for a very long time. In that moral sense, I would say most religions are morally right, in the sense that they are useful and helpful and support us.
Having said that several commit human sacrifice: Satanists; certain Hindu sects; the Baals; the Incas; the Norse Gods; the Roman gods. These cultures have died out or gone underground or have exceedingly few members.
Evolution has its toll on religions and cultures as much on individual animals. The evolution of religions is a lot faster than with animals because we can change our mind and learn.
The most successful religion by far is Christianity with 2.4 billion members because it gives many more benefits to its followers than any other belief system. The Muslims come a relatively close second with 1.7 billion.
However, most Christians think that there is a thing called the Universal Church made up of all the Christians from all denominations, even if they disagree with the details of their customs and beliefs. There are only a few very small minority groups who still kill heretics. Most of the heretic burning has died a death as a bad idea.
However, the Muslim religion has been broken down the middle between the Sunni and the Shiite since the death of Mohmed the prophet. Muslims are much more likely to fight another Muslim about their beliefs than anyone else. The IS and the Taliban still kill other non-believers and heretics for being wrong. It is also a capital offence for a Muslim to stop being a Muslim.
On the other hand, Christianity is a completely voluntary organisation. The Christian religion as a political organisation is far more powerful and more successful than the USA and China put together.
So as political organisations they are exceedingly successful. Most businessmen think that success implies you got it right. So in that sense, I would say Christianity got it right because it is the most successful
Does that make the beliefs logically true? Of course not, but most people find them the most useful.
Some claim that there are, logical proofs that Yahweh exists. So Christians may be the closest to being logically right too. Although disagreeing about almost the whole Bible, I doubt if any are closer to understanding god than you or me.
However, being logically right is no indication of usefulness.
Certainly, Donald Trump finds little use for logic.
