COMMUNION IS EVERLASTING
Communion is sharing. Sharing the experience of ritual crucifixion and resurrection of the body of Christ, within the body of Christ, by bread and "wine," so as to keep afresh his hope, his promise, his memory in the minds of believers, all of which were embodied in Jesus Christ's divine visitation as "son of man" to earth and his prospective return to earth at some unknown, future era.
Observance of communal rituals like communion, like Christmas, are convivial ties that bind people with or to each other, with overarching ideas, values, beliefs, behaviors of one's forebears, society members.
Yet, all life on earth is dynamically changing continuously. This too shall pass, as others have passed.
Evidence of extinct, former human and non-human societies, and advanced civilizations, that all had different communities, different communions, binding rituals, ideas, values, beliefs, behaviors dating back thousands, if not hundreds of millions of years, upon the same earth as we, are being uncovered, recovered, or evaluated each day.
Someday, it is inevitable that, at some time, it may well be, as we exhume the remains of ancestors, future civilizations will exhume us.
Thereby the eternal communion of life's rituals continues. As these go let others come to the table to sup.
