Was curiours to what a rabbit has to do with Easter and came across this tid bit of info. Thought it was interesting and well put.
What has become today's Easter Bunny is actually a surviving remnant of much older traditions celebrated in pre-Christian days, and still practised today by Pagans around the world. Bunnies, or rabbits, are
fertility symbols, sacred to the Goddess of the Dawn, once known as Ostarra or Eostara, which is from where Easter takes its name. Due to the rabbits' ability to procreate at light speed, the rabbit is a perfect symbol for fertility, which is a focus of natural life cycles in the spring. Eggs, too, are a natural symbol for fertility - from the egg comes life.
During Spring Equinox celebrations both past and present, the focus is on Spring growth. All the blossoms on the trees, new shoots of flowers popping up above the ground, and new born animals, including the ever producing rabbit, are all signs for us to see that the season of Spring has begun and nature continues its cycle as ever before.
When Christianity began to spread, one way of getting Pagans to accept the newest religion was to overlap Christian values and ideas with current and much loved pagan customs, to attract the locals to the church and pull them away from their long practised ways of honoring and living with nature. The Easter Bunny and Egg hunts are two such carryovers that, in the beginning, had nothing to do with the Christian faith or belief in Jesus' resurrection. But these pagan ideas helped those wandering priests to get the attention of the pagans they sought to convert. Pagans around Europe loved their goddesses and symbols of life that they understood much more clearly than the Bible, which was not readily available to the common people anyway. Incorporating these pagan practices was discovered to be a key ingredient to bring more people under the church, and it made Christianity itself more acceptable. After all, the most successful missionaries are those who seek to understand the people they wish to convert by living their life without compromising anyone's beliefs. Because the Christian church celebrates the Resurrection of Christ in the spring, it made sense to them to "borrow" from Pagan Spring rites in order to make the attraction to the newer religion plausible.The short answer is: Rabbits (and eggs) have come to be seen as symbols of new life and rebirth, and the Christian celebration of Easter is all about new life, because of Christ's resurrection, and the new life He bought for us.
