In China, the written word for apple is "ping" which is also the word for "peace" . To the Chinese apples represent peace, while their blossoms represent beauty. The Celts highly praise the apple and their symbolic meaning includes love, truth, peace, beauty, honesty, romance, fertility and remembrance. All things that make up a marriage. The celts saw the apple as a treasure, especially for it's ability to stay ripe over a long period of time (when stored in a cool, dry place) . This was symbolic to a lasting love. Meaning, love is present even after the peak of ripeness and that long after the passion subsides, love is still there. Long past the honeymoon, when simple companionship is all that is needed, love lingers.
I would love to write a wedding with an apple twist. I would do so using these stories and symbolisms. At the altar table would be a beautiful vintage teapot full of hot, spiced, apple cider. Two vintage tea cups would sit by it's side (this is especially fitting for a autumn or winter ceremony). The couple would be reminded of celtic symbolism for apple and loving completely, through the passing of time. And then I would pour them their spiced cider and with a toast, bless them with a love everlasting, peace, honesty, truth, romance, remembrance and a beautiful life (all things that represent the apple, as well as marriage). The same idea could actually be done with a real apple, sitting deliciously on an altar table. The officiate speaks of the symbolic meanings of the apple and the couple each shares a bite.
Spiced apple cider can be served at the reception and apples could be used throughout the wedding decor.
