I don't see this, sorry. Your beliefs are based on faith. .
My faith is based on evidence. But these evidences are based on significant unbiased investigation. I mentioned very briefly in my last post for you. I don't believe in blind faith.
In your own words the "original message" was corrupted, distorted, if not outright changed.
No, Let me try giving you a logical argument;
I looked at the teaching of major religions: Religions A, B, C, D, E...
When I actually went and read the scriptures from these major religions, I saw they are all giving the same fundamental message.
I call this "the original message"
But when I go and investigate to see what the followers of each of these religion believe about their own religions, then I found out, the followeres of these religions, each one turned their religion into sects, and each sect interpretes their Book differently.
Then, I realized the reason that people cannot see how these religions came from the same source, is because each one interpretes them differently.
How would we ever be able to know what the "original message" was, if there were one?
Because I see a "Complex Knowledge" in all Scriptures which IMO is beyond the ability of a regular human being to write that. I see the same fundamental message.
I see it is the same Author that wrote these Books in different Ages and different locations. But It requires investigation.
If the same force/being was trying to bring humanity together, wouldn't it make sense for it to leave obvious clues/signs that would prove your point and aid the unification of mankind?
It wouldn't make sense to do it easily. I tell you why.
Suppose a person wants to get a Phd degree. The option A is the person is just given the Phd paper and is called Dr. without studying and learning anything.
Option B is that person has to study and make an effort to actually earn the knowledge then get the Phd degree and be called Dr.
Apply this with "knowledge to see the Truth"
Option A is that, God sends some big miracles from sky, and send an imortal person, so, every person has to believe without making an effort.
Option B is God makes it difficault for mankind to see the truth, so only when a person makes a true effort to Open His insite, to clear His hearth from every Bias and become absolute sincere, only then he can see the truth and get that true degree of spirituality.
If you were God, which option you give? any other option?
So, why does it choose to only talk to one person every few centuries or so?
Because there is the Sun, the Moon, the planets and stars. To me you are saying why God didn't create only the Suns.
No, In our galaxy, He created only One Sun who appears every morning to give light. While in the Nite the Moon and stars give light.
Likewise, He created divine Messengers who appear in every Age to give light, and when He dies, then the Moon and Stars who are the truely spiritual people to give light( Not the clergy, they are fallen stars in this Age). There are signs in this. He wanted to create everyone and every thing.
The Manifestation of God who are the Divine Messengers, God does not talk to them literally. They have innate knowledge, like the Sun, they have their own light, while every one else get their light from the Sun in different degrees.
