Is it justified to interpret someone's scriptures differently than those the scripture belongs to?
For example, the New Age teaching that Jesus was a guru who lived in India, and that he was teaching a form of eastern religion.
No one owns God's Word.
We all are responsible for our own approach to them, how to see what is contained within and how to live them.
Did Jesus go to India? Did he go to the Americas? Did his Spirit come back in a man from Persia?
No one "owns" God's Word? Yes, they do. Each religion claims to have some kind of "Truth" whether it is from a prophet, an angel, from a dream or vision or an incarnation of a God or whatever. The person who had that "Truth" and told it or gave it in a book to others, set some rules on how it should be followed. Even the Baha'i Faith has rules on how to obey and interpret Baha'i Writings. I can't come along and say that I have a new and better interpretation of the Baha'i Faith.
New religions, however, run into the problem of having to change people's beliefs about the older religions to give people a reason to switch and follow the new one. Christians dumped the Law from Judaism. They might pretend they didn't, but they don't follow the Law... a Law supposedly given by God. The Christians interpret the Jewish Scriptures to show how the Law was temporary and how people need Jesus to get saved from the penalty of sin.
Then now what? Baha'is reinterpret all the Scriptures of all religions to show how the old laws were from God but only temporary. They eliminate the Christian need to be "saved", because Baha'is eliminate the belief that if a person dies without believing in Jesus they won't go to hell, because they isn't such a place.
So the justification is that the new religion believes the old religions and their Scriptures are flawed or even false. And their "Truth" needs to be told to made things right and give people the real new improved "Truth". But then, there is the same problem. All the new religions contradict each other. So what's true and what's made up baloney? I got a feeling it's not "all" God's Words.
