As with almost all "Christian" holidays, Easter has been secularized and commercialized. The dichotomous nature of Easter and its symbols, however, is not necessarily a modern fabrication.
Since its conception as a holy celebration in the second century, Easter has had its non-religious side. In fact, Easter was originally a pagan festival. The ancient Saxons celebrated the return of spring with an uproarious festival commemorating their goddess of offspring and of springtime, Eastre. When the second-century Christian missionaries encountered the tribes of the north with their pagan celebrations, they attempted to convert them to Christianity. They did so, however, in a clandestine manner.
It would have been suicide for the very early Christian converts to celebrate their holy days with observances that did not coincide with celebrations that already existed. To save lives, the missionaries cleverly decided to spread their religious message slowly throughout the populations by allowing them to continue to celebrate pagan feasts, but to do so in a Christian manner.
As it happened, the pagan festival of Eastre occurred at the same time of year as the Christian observance of the Resurrection of Christ. It made sense, therefore, to alter the festival itself, to make it a Christian celebration as converts were slowly won over. The early name, Eastre, was eventually changed to its modern spelling, Easter.
The Easter Bunny
The Easter bunny is not a modern invention. The symbol originated with the pagan festival of Eastre. The goddess, Eastre, was worshipped by the Anglo-Saxons through her earthly symbol, the rabbit.
The Germans brought the symbol of the Easter rabbit to America. It was widely ignored by other Christians until shortly after the Civil War. In fact, Easter itself was not widely celebrate in America until after that time.
