>>it's simple as this, you or me can not judge who is part of a religion and who isn't --that's just taking ourself into the position of God which is extremely diss-respectufull<<
How does God come into play here? You can bring up God and call something disrespectful, but you're still not making any sense. Religions are socially defined and constructed. The people who created/take part in religions define them. They define their dogma and doctrine. They make up the religion and determine what standards there are for their religion. Maybe everyone who accepts Jesus as their "personal Lord and Savior" is a member. Maybe only those who believe in the trinity and follow certain moral practices is a member. These standards are determined by the communities of religions who make up those religions.
Religions did not come to humanity from God. They are constructed by people, made up of the people who take part in them in whatever structure the religion has set up (by human beings, not God). As such, they can decide whatever they want to be their beliefs. And they can decide how closely one must follow those beliefs, however specifically, in order to accept that person as a member of their religious tradition.
The question is, who are you to tell them they can't determine what constitutes their religion?
>>now on the basis we judge these people to be religous or not are just someone's interpretations<<
No they're not. Religions have set forth the standards by which they define themselves. Some people just don't meet those standards. It's not a matter of interpretation.
>>omeone who is very religous and very devoted but his interpretations will be different from another person because some of the factors that play a role in his interpretations<<
Such a person, if their "interpretations" are at odds with a religion's doctrine, is probably not a member of that religious community. He/she may be a part of the broader community, such as a nondenominational Christian, but if he/she has significantly different doctrine than the Catholics or various Protestant faiths, then he/she is not a member of those religious communities, while still being a nondenominational Christian. But Christian is not Catholic or one of the various Protestant faiths; they have doctrine, and if someone does not agree with that doctrine, then they're not a member of that tradition.
>>SURE, his interpretations could be true, they could really be the exact points of that religion<<
And there's NO ONE better to judge this than the members of that religion's community. And they all have doctrine. Whatever a person's interpretations are, if they are not the interpretations of that religion, then the person is following some other faith than that religion. Religions are socially constructed (for the 900th time). I don't know if you're talking about divine revelation when you use the word "true" here, but regardless, if a person's interpretation is not that of a religion, then the religion will not identify the person as a member of their religious tradition/community. A person can call themself ANYthing they want. I can call myself a devout Muslim. But that doesn't mean anything. Muslim clerics wouldn't call me Muslim. And they'd be totally right.
>>but we DO NOT know that for certain, we can only assume that<<
Yes we do. Many religions publish literature making their doctrine as clear as you could possibly want to know it. Since they decide what constitutes their religion, this is essentially working with the purest, most certain facts about those religions as possible.
>>, but we should not say this is our religion<<
Unless, of course, we actually accept the doctrine of that religion and it is, in fact, our religion?
You're a nondenominational Christian? You keep mentioning God and his role in judgement as if it has anything to do with this thread. You can be a nondenominational Christian. Everyone has their own interpretations. And since they're just bread and butter Christians, that works. But nondenominational Christians are not Catholics. They are not Lutherans. They are not Presbyterian. They know it and so do members of those faiths. It's not a matter of judging someone to examine their doctrine and see where it is the same/is not the same as someone else's.
