Well we can't have peace while each religion considers itself superior to all the others and all others are to be condemned. This has led to and is continuing to lead to wars and conflict.
There is truth in all the religions and none is superior. Religious fanaticism is very harmful. Religion is meant to create harmony and peace not destruction.
And right here I must point out that you are wrong. It seems to harmless to state that "all religions" have truth and "none are superior". But when you look at it, it is a terrible mistake to do so.
Why? Because, quite simply,
people often hold tragically misguided beliefs. That is just a plain fact that we all must deal with, even as we do our best to attain mutual respect and understanding.
We can't have or even truly approach harmony and the avoidance of fanaticism if we feel duty-bound to treat misguided beliefs as if they were valid. Or instead, only slightly better a choice, to convince ourselves that those beliefs are somehow not worth of consideration despite our own self-imposed goal of respecting "all religions".
That is just not something that can be made to work. It is attempting to deal with a very real challenge by pretending that it needs no true effort. It is hoping for things to magically fall into place to our convenience despite a conscious refusal to acknowledge the need to do something to solve conflicts.
Religious disagreement should be embraced and clearly stated, not glossed over.
It is ok to disagree and learn to live with that.
It is even ok to think that one's beliefs are more correct than those of others, as long as we also understand that each person must ultimately make his or her own choices far as religious matters go.
It helps to realize that different people will actually have different needs and different abilities to handle various religious concepts and models. Which is to say, there is no single religious approach that will be better for everyone. Some people need more in the way of artistic inspiration, others need social interaction or concrete, undeniable, tangible attainments in this world. That is just how things are and what we should deal with.
Sure, it can be troubling to deal with the idea of some people simply needing to go in directions that are unhealthy for ourselves. It used to be very difficult for me to accept that.
Harmful interpretations and misconceptions have led religionists to believe only their religion is true and all others are false.
True enough.
Is there a more moderate and unifying interpretation of all these seemingly conflicting religions? We believe there is a way of seeing them as complimentary.
For that to be possible, such an interpretation would need to be not so much "moderate" as it would actually need to be bold, ambitious and complex. Religion needs an edge of sorts to make much of a difference. It must connect with and respect the deeper, most difficult aspects of each person. Moderation is not always possible or advisable in such a deeply personal field. Specifically, quite a few people need to develop and nurture their passion outright, to learn to be more daring and more extreme (despite that very approach being dangerous and poisonous to others). Half of healthy religion is acknowledging who the practicioner is.
It is quite easy to accept each other's Faith if we discard the concept that our religion is superior. Oneness emphasises the harmony of all religions and tries to educate that they are all truth and none is superior. The emphasis of superiority comes from the immaturity of the leaders of religion who, instead of promoting love and harmony often promote an agenda of superiority, that their brand are the 'chosen people' and this is harmful.
I hope I am wrong, but it sure sounds that you hope that all people will eventually be convinced of the One True Way and we should simply be patient (as opposed to understanding, respectful and questioning) if they do not seem inclined to cooperate with that hope.
