Human Reason and Christian Denominations

[Bahana]

What's interesting to me about all the different sects of Christianity is that it is a prime example of humans using their own reason to create a belief system. Look at how varied some denominations are. Some will allow a homosexual to lead a church while others will not let a known gay person through the door. They all use the same Bible but use their own reason to decide what parts to emphasize and how to properly interpret scripture. It's not like some supernatural being is communicating them to tell them exactly what to do. If some Christians here believe that is the case then feel free to provide evidence of your communication with this being.
