You haven’t got my message.
When i say that religion is blind faith i mean that religions do not allow the people who follow such a religion to believe in what is written in other books and marking them as heretics.
So only their book carry the truth, all the rest is sort of heretic.
From here i can understand that the truth according to religion is their truth and that is the end of the story.
In other words the options for a search are all gone.
That’s only true to a certain extent. Abrahamic faiths are probably the only religions that assert necessary worship and belief in no other god than their specific God (and a few other things). That is not to say that you
have to worship this God in order to be pious, just that you not worship a false one. For example, Jews discourage gentiles to convert to Judaism, and instead recommend following the Noahide laws (seven key commandments), in which idolatry is forbidden (but worshipping Jehovah is not necessary), and in Catholicism, non-Catholics and non-Christians can be saved.
In many other major religions, namely the eastern and dharmic religions, idolatry is seldom problematic considering theism isn’t a prominent theme in them. The only major eastern religion that truly is theistic (let alone monotheistic) is Sikhism; even Hinduism, in the end, is atheistic, as creator deity Brahma really actually just “emanates” from Brahman, or Absolute, ultimate reality. All other gods in Hinduism (Shiva, Vishnu, Ganesha, Shakti, etc.) are manifestations of the same transcendent reality. In fact, eastern religions tend to be very open-minded to other religions, provided love and compassion are key elements to the faiths.
That said, you may follow any religious law you like that isn’t of your own religion, provided it doesn’t contradict your religion. For example, being a vegetarian
because you believe in animal rights is not forbidden by the bible, but that same book doesn’t tell you you need to become one to be pious. However, if you’re a vegetarian because you abide to the animism of Jainism, you’re contradicting Christianity.
By the way, I think you don’t understand the definition of ‘heresy’. Heresy refers to teachings that divert from traditional ones offered by the church. However, it is only considered heresy according to the church itself. In other words, consubstantiation is a heresy in Catholicism (I would think so, anyway), but is commonplace in Lutheranism.
That said, by definition, what may be considered heretical to a church or religious body is not heretical to a completely unrelated or unaffiliated religious body or church. Karma, found within Hinduism, Buddhism, Jainism and Sikhism, isn’t heretical to traditional Christians as it is not an ‘offshoot’ of Christianity. Mainstream Christians believe karma to be
false, but that doesn’t make it a heresy. What
would make it a heresy is if someone, such as theologian John Hick, tried to reconcile the idea of karma with traditionally-taught beliefs in Christianity.
Christianity started off as a heretical sect in Judaism, for instance.
I don’t think anyone can give you an easy answer to your question. Yes, all religion seems to be based on blind faith, but there are philosopher/theologians, such as Thomas Aquinas who stress that faith must be based on reason, and that there is truth to be found in all human thought.
Although I’m not very familiar with his work, Soren Kierkegaard seems to have some interesting ideas regarding this. I also enjoy the fact that he looks at issues from every angle (religious, agnostic, atheistic) and, as a devout and staunch Catholic, had the humbleness to point out the flaws and controversies within Christendom and his local Church of Denmark. Self-criticism is a basis for a lot of my own philosophy.
