A ceremony (UK'sɛrɪməni, USˈsɛrəˌmoʊni) is a unified ritualistic event with a purpose, usually consisting of a number of artistic components, performed on a special occasion.
The word may be of Etruscan origin, via the Latin caerimonia.
According to Dally Messenger and Alain de Botton, in most Western countries the values and ideals articulated in both church and civil ceremonies are generally similar. The difference is in what Messenger calls the "supernatural infrastructure" or de Botton the "implausible supernatural element".
Most religions claim some extra advantage conferred by the deity, e.g., Roman Catholics believe that through the words of consecration in the mass ceremony, God himself becomes actually present on the altar.
Both religious and civil ceremonies share the powerful psychological, social and cultural influences which all ceremony seeks to attain. Obviously, the style of music played, words used, other components and the structure vary.
As Edward Schillebeeckx writes about the marriage ceremony, there are a number of ancient traditional elements in both church and civil ceremonies in the western world. Key ceremonies date from the pre-Christian Roman and Greek times, and their practices have continued through the centuries. For example, from pre-Christian Roman times in the marriage ceremony, we inherit best men and bridesmaids, processions, signing of the contract, exchange of rings and the wedding cake.
Writer and philosopher de Botton maintains atheists should appropriate many of the useful insights, artistic treasures and symbolism inspired by religion. He argues that the secular world can also learn from the religions the importance of community and continuity. Messenger agrees, and points out that the success of civil celebrants in Australia has been partly due to their espousing of these principles, both in theory and practice, since 1973.
The main impetus to the development of quality civil ceremonies in the Western world was the foresight of the Australian statesman, senator and high court judge, Lionel Murphy.
