To believe that one religion is superior to any other is an extremely dangerous ideology. Take it from one who has suffered from being among the less desirable believers, in a society where one religion was considered the better. Just look at history, recent and past, then know how such a concept results in sorrow and death. Usually the death of innocents and the sorrow of those left behind.
Let us take Christianity and see how fundamentalists of that faith will deny the beliefs of non-Christians; Jews, Hindus, Moslems, Confucians and so forth. Off went the missionaries to convert the 'heathens.' The blood shed in the name of Christ must make him weep. And still this continues.
Then think of the Moslem fundamentalists, who are prepared to wage a 'holy' war, a jihad that encourages young believers to die, and to kill as many others - non-believers - as possible in the process. Or the Spanish in South America, the Portuguese in India, all secure in the belief that their religion must be imposed on others, simply based on the premise that it is 'better.' Moving back and forth through history, it is clear that by thinking one religion is better than another brings only fear, mistrust and subjugation.
One of the most lasting and influential experiences of my life occurred when, in my teens, I met members of the Ba'Hai World Faith. These people had fled an Iran ruled by the Ayatollah Khomeni. They were persecuted for their non-Moslem beliefs, and I am talking mid 20th century, yet they accepted the prophets, beliefs, and rights of others to practice their own faiths. Believing in progressive revelation, and living their faith in the most kind and charitable ways imaginable, those people of one persecuted religion, taught me more about Christian values than years of Catholic dogma.
From the East, India in fact, the tenets of the Sikh religion, to protect the innocent, work hard and share goodness, also appeals. The same with Islam, where giving to those in need is mandatory. The Buddhist faith, wherein we should treat all things as valuable and seek to help them and ourselves further on the wheel of Kharma, is a wonderful belief system. The Chinese Tao offers a way to be, a philosophy of letting what will be, happen, an acceptance of life and nature, a way of peace.
Given all the faiths and all the honest dedication to beliefs that exist in the world, how can we say that any one religion is better than another? In many ways, religions have developed as systems to ensure ethical and moral societies. Their rules, rituals, their priests and leaders, all helped to give some semblance of law and order, some sense of cohesive belonging, which man craves and needs. I consider the Native American and Australian Aboriginal beliefs in the powers of nature and the universe to be the most beautiful 'religions' available. One god or many, no good can come of treating one religion as better than another. If man has a soul, which I am almost convinced he has, then let him feed and nurture its goodness in whatever way makes him live a happier and better life. Religion can assist or destroy that process, it is a matter of informed choice and free will. May your gods be with you.
