Pantheism is worship that admits or tolerates all interpretations of deities. The human race exists throughout the multiverse, which was created and designed by God. Some are worlds that are completely run by democratic governments, while others are totalitarian empires that practice slavery. Some have cultures that lean toward matriarchies, while others are war-torn conflict zones similar to Mad-Max. All of these realms worship the same creator, but express that worship in different ways. Some see him as an all powerful, omnipotent deity, while others view God as different aspects that make up a whole, or multiple smaller deities led by a main deity.
Angels are stewards of this god who exist to keep the universe functioning. They are similar to computer programs, which are written to make the verse work in the background, but are unable to interfere directly with the inhabitants. People know of these angels and the existence of their creator as fact. These beings operate with semi-independence. They can form their own opinions on matters, but must stick to their defined task and are not capable of disobeying universal laws.The angels periodically visit these realms and communicate with humanity at certain times during a millenia, but don't enforce any particular world view. Their job is ultimately to protect the versed from threats and keep it working according to the original design (fighting off stewards from competing gods, laws of gravity, etc).
The problem I have is how these angels would interact with humanity and how they justify the worship of a God that has no rules of how to worship. Ex: someone asks them certain questions about world views or morality, such as whether slavery or oppression of certain races or lifestyles, or modes of governing. The angels can't just come out and say "God doesn't care how you worship it, just that you worship it". This seems inauthentic and indifferent, and may push people to just not worship God at all.
Why would people devote worship to a god with no moral authority?
