Theoretically, of course there should be only one religion. Why not? If Christianity is RIGHT, then Islam is WRONG - and vice versa. Further, if Christianity is RIGHT, then concerning each precisely-worded proposition within Christianity, only one position is true. I'll give an example within Christianity. It is universally admitted that immersion is baptism. Nobody denies it. Why sprinkle or pour? Some believe it is permissible. Others deny it. Why contend over it? Practice that which is universally conceded. Do not risk the questionable. That'll solve half of the issues.
In order to maintain peace, the world should only have one religion because we're all in the creators view. It will also help in resolving religious crisis which will save our precious lives when peace and order is maintained. We would all be brothers and sisters. That is if the world is going to have just one religion...
Thoughts of the world eventually having one religion is absurd. Various religions have been around for a very long time. The population has different views concerning their belief. To change to one religious world wide would not work. Once an individual has settled into a belief it is rare to change their thoughts on religious issues.
This would go against the bill of rights and all of the people of the worlds morals and beliefs . The one and only god says to only worship him and his son. Some people say otherwise but there wrong ! It is crazy to think this it would not solve any world problems
Logically speaking the world should only have one religion (if any) because only one religion (if any) can be completely true. However, the lack of proof and evidence of what religion (if any) among the ones believed today and even the ones not yet comprehended means that we do not know and cannot determine which religion (if any) is true. As such, at this point in time the world should not have one religion for one cannot implement and force any one religion on everyone in the world for there is no proof supporting that religion and the fact that it is the truth.
The question is this: can the entire world accept one religion without having irrefutable proof that it is both the truth and fact? In short, no. This is because there will be many who would oppose this religion and pick it apart because of the lack of evidence. It is what is being done even now, because now all religions are merely theories that are entirely possible, but have neither been proven or disproven. Therefore one cannot state which (if any) is the truth and which (if any) the entire world should believe in.
Honestly, i think religion is overrated. Its good to have a belief in god but why are you condemning someone for calling this god by a different name if he/she does the same thing and teaches us to live a virtuous and holy life?. There is a difference between religion and spirituality but unfortunately not much people see this.
I do not think there should just be one solid religion in the world. Us as humans in the world have different beliefs and cultures, which would naturally equal different kind of religion. Not to mention, having different kinds of religion can also be very education for people who are interested.
In reality, there's no reason that the world should have only one religion. No single religion would satisfy the needs and beliefs of every person on the planet. Multiple religions allow the people of the world to believe in what they want to believe rather then being forced to believe one thing.
There are many ways to look at this. Most religions teach there is only one true religion so then it makes sense the world has only one religion. Hiowever if you dont beleive any of the religions are real then one religion is still one too many religions in the world.
There are so many different cultures and traditions in the world, that there can't be "one" religion for all. It's important to respect the beliefs of others. People should celebrate their beliefs in so many different ways and be able to pass on their religious traditions to their children. I believe that being aware of so many different religions can sometimes serve to strengthen one's core religion.
There are many types of people and they have and should have many different ideas of what religion is and what to expect from religion. No one religion would ever be a good fit for everyone and it would be nearly impossible for one religion to encompass the differences in societal expectations in the world. It would be great if all religions had a disclaimer somewhere reading "I believe, you believe, we all believe in something. It's okay to believe in something different!"
Religion does not seek truth. Instead it uses dogma to insist that it is right, regardless of whatever contradictory evidence, facts, or reasoning is brought forward. Should there be a single religion? No, it should be as it is, with fractured groups everywhere each believing themselves to be right and everyone else wrong. Immune from reason, they have no pathway to unifying themselves. If we take "should" to mean pointing to the best outcome, the answer is still no. The world should have no religions (theologies) as they are uniformly false and most are destructive.
The idea that all religious humans on Earth would band together and follow the same religion is a ridiculous notion. All you have to do is peruse the Internet for about five minutes and you're likely to find some type of text, whether it be an article or a conversation, that will show just how rigid some people are in their faith. And even if there were one world religion, you would still have different sects within it like you see today in all of the world's religions.
