In the history a lot of wars were fought in the name of god and faith. And this although they are all talking about peace and charity.
The reason: There are multiple reasons causing wrong usage of religions.
- There are a few people misunderstanding the religion they practice.
In addition to that some are misusing and manipulating the faith of other people practicing the same religion.
- People are uncertain about themselves and other religions cause anxiety to them.
This mostly leads to arguing about other religions trying to decry them.
- People are too certain about themselves and therefore only their way must be the correct one.
They forget that different people need different medicines for healing their different illnesses. This does not mean that the final goal is the same for everybody - personal happiness.
The solution: We must understand that the intention of the religions are all the same: They are systems of rules and world-view to assist people living together in peace to support the surviving.
Single individuals are in the very most cases not able to live independently from other people. We all depend from other people supporting us with clothes, food and so on. The conjunction let us understand that if other people stay well and be happy will have affect also on our own happiness.
We should respect the fact that different ways may lead to the same final destination - a world full of peace and love. We should therefore pay respect to all religions. You should accept that the religion you practice is not the only possible way and there are different interpretations. Even people not practicing any religion may follow similar rules or at least have the same intention of living together in peace and love with the others - and maybe those people have chosen to practice none of the religions only because they would have liked to join all of them...
When you go to a land or location where other religions are practiced then treat them with respect. Maybe it is not doing harm to you trying one or the other practice of that religion. Celebrating with others improves the understanding the others but does not mean that you cannot have your own view of the world. It is a matter of respect and empathy.
