How Did Easter Become an Important Celebration
Origins of Easter
While there is no universal agreement, the term Easter may derive from the goddess Eostre, who is the goddess of spring and often associated with fertility in Germanic and Norse traditions. Traditionally, the spring equinox, when darkness and day are the same amount of time, was seen as a holy period that signified the coming time of plenty and the agricultural cycle. It is possible the goddess may connect to the ancient Near East, where the goddess Ishtar also had associations with fertility and was celebrated at about the same time as her significant holiday. Eostre was also associated with rabbits and hares, which seem to be retained as symbols for Easter, where in the pre-Christian tradition rabbits and hares symbolized new life, as these creatures reappeared after winter. Similarly, Christianity used these symbols of life in relation to the life that Jesus gave his followers.
Both in Near Eastern and ancient European traditions, the spring equinox was a time of religious festivals that focused on sexuality and fertility. The ancient Babylonians had a "sacred marriage" ceremony where the king would ritualistically have sex with a female representative of the goddess Ishtar. These rituals were seen as critical in continuing life as they allowed its rejuvenation after winter. Eostre seems to be associated with many Indo-European goddesses and as Indo-Europeans migrated from India and through Anatolia, it is possible the traditions of Eostre mixed or were influenced by or along with traditions of Ishtar.
Interestingly, for other European cultures, the term for Easter derives from Passover. In essence, it was the Northern European Germanic traditions that may have retained their older holiday names, while southern European or Latin and Greek influenced cultures utilized a new name after their conversions. It is also likely that the southern European cultures, which converted earlier than in Northern Europe, had more time to assimilate their older traditions with Christianity.
The importance of the spring equinox could not be understated, given the importance of agriculture. For the early Christian church, the time of the Passover was seen as the most important period in the Christian calendar. The importance of Passover, falling near the time of the pagan spring celebrations, may have influenced the Church to decide in 325AD, in the Council of Nicaea, to have Easter fall on the Sunday following the first full moon after the spring equinox. In effect, this puts it near but not exactly at the same time as the pagan rituals. Furthermore, the Church made this celebration a moveable holiday and not fixed. This gives it a range between March 25-April 25 each year, depending on the particular year.
As the church developed the holiday and Christianity spread in the early Medieval period in Europe, particularly in Northern Europe, past pagan traditions of using eggs and rabbits as symbols of fertility and celebration of new life, the Christian church began to use these symbols to reflect them on Jesus as the life giver. In essence, this retained many of the symbols while reorienting the meaning. Initially, it is likely the celebration may have not changed very much in the 4th and 5th century CE, but as the Church's influence spread the holiday began to develop its own new symbols and traditions.The fire used in Mass, for instance, may have connections to worshiping of the sun but in Christian traditions the meaning and importance of the sun was transformed as symbols for the importance of Christ giving light and salvation.
