Ceremony is a necessary outwork of manners as well as of religion... it keeps the petulant at a proper distance on the one hand and on the other it is a very small restraint to the sensible and well-bred part of the world.
A Ceremony is a technical procedure for teaching indemonstrable truths. Ritual and pomp overcome man’s blindness before what is not material and coarse.
Ceremony is responsible for assisting people to adjust to change (a marriage ceremony does this for families), to recognizing achievement (a classic example is a graduation ceremony), to relating, to expressing love, and/or to establishing a relationship.
Ceremony is the human way we have to signpost a deal such as a business merger, to trigger off a healthy grief process (such as in divorce or funeral ceremonies), to welcome another human being into the family. So Ceremonies have these excellent effects - they can be used further to announce intentions, to express loyalty and to reinforce a sense of identity.
