Of course like so many other 'important' dates in the christian calendar, it is based almost entirely on much earlier, pagan festivities.
The celebration of the new life of Spring goes back much, much longer than two thousand years, and often involved the death of the old 'king' and then his re-birth usually in the shape of a new younger version. At one time, the old king would actually be killed having had a wonderful year of having everything the society could give him. New one selected and it started all over again. As time went on, the old kings; decided they would like to live through this period, so their 'deaths' became just pretend.
Early christianity were very good at adapting older religious believes and practices, and thereby not upsetting local populations too much.
Easter eggs, are very much added to part of this, although it is easy to say they represent something. Can do that about anything when required.
My best easter memories are back inthe early 1960's when I was spent the four days on the Aldermaston, anti-nuclear bomb CND marches.
Our local Youth CND would meet up early that morning, dressed appropriately, and with some changes of cloths in bag and our sleeping bags. Get a coach down to the arranged start point.
Thousands upon thousands of us, all ages, from all over the country. The organisation was incredible (I can appreciate it more now than I did then, when I just accepted it). Each group was given a colour tag (for your area) and a number. Cannot remember our number but we were Magenta!!!
Bags, and sleeping bags all loaded on lorries, these took them to where we would be staying overnight - in churches, schools, sports centres, village halls, etc. One year, when Reading town council prevented us using any of their facilities, in hug marquees, and many of us put up by local people in their homes.
One year, in an attempt to keep a control on numbers, all groups coming from the east of the England, started off in Finchingfield in Essex, and going through Essex and East London on those first three days.
Easter Monday was the day we came through London for a final meeting in Trafalgar Square - although, often we would not all fit in there. Even all these years later, I can remember the kindness we were often met with, with people handing us fruits and other foods, two children standing with their parents carrying posters with their names on and saying 'Thank You Marchers'.
So much hope we had then, and genuinely believed that if we managed to avoid nuclear holocaust, then life would get better and better. So glad I had no gift of foresight, to see what a horrible place this world has become.
