There, in Holy Trinity, are still the old banners, and among them was one that we children called the 'eggy banner'. It had a very fine, large, gold egg cup in which sat something which was evidently an Easter egg with a great effulgence springing out from it. Each Sunday morning we had a boiled egg for breakfast, and I Suppose it was natural that I should associate the celebration of the risen life in Church with the cracking of an eggshell. It was only later, when I was introduced to more sophisticated ways and saw a monstrance in use for the first time that I realized what that banner represented and why it was always given pride of place in the procession. And I see the liturgical tradition developing in those ways too, as we learn to value the rich diversity of the many strands of our inheritance and learn to say 'no' to the flat unison which is narrow, exclusive and boring.
Most dioceses have their own local groups to undertake similar projects themselves.
