The simplest definition of Eternalism.

If you think, feel, believe, know or understand that time is a real, actual thing, AND if you feel, believe, know or understand that time has no beginning or end, then you are an Eternalist.

All conjecture of the meanings beyond this are personal and social ramifications. As such they may entice the Eternalist to unite with others of like mind to gather knowledge and support one another against biased laws and practices used against them by those who have been conditioned by bias and dogma. Included in social aspects of the Eternalist Faith are the symbol, related art and ceremonies, all designed for the enjoyment, entertainment and enlightenment of all who share a basic understanding of time.
