Religion

Faith is a personal relationship with a supernatural entitiy or entities. Its natural to want to share a satisfying relationship with others.

When two or more people gather together to celebrate their individual relationship with the supernatural they cross into the realm of religion. As the group gets larger, humanity (less than supernatural) takes over and the group becomes an "organized" religion.

Problems begin when groups of people who believe that they have exactly the same personal relationship find out that they don't and splits and schisms begin.

The situation gets even worse when some religions think their relationship and/or organization is "better" than the expressed relationship and/or organization of others.

With years of separation and contempt the differences can and often devolve into prejudice, hate and violence.

There is a way back - focus on your personal relationship and allow others to have their own personal relationship. This would apply equally to those who may be within your religion or individual organization and those who are in other religions or church. But also to those who choose not to have a relationship with a supernatural entity or those who don't believe that a supernatural entity exists.
