My Christian denomination, along with some others, celebrates the time between January 6 and Ash Wednesday as the season of Epiphany. In common use an epiphany is a sudden moment of awareness — an "ah ha" moment. Etymologically, an epiphany is a shining (“-pha’’-) forth (“epi-“), a manifestation of light. In Christian tradition, this shining forth is the coming of Jesus into the world, a coming through which we all may shine.
Long before Northern Europeans established the Clausian gift-giving tradition, early Christians in the Mediterranean region celebrated the Epiphany by exchanging gifts in the tradition of the three kings mentioned in the bible. Though they are not mentioned by name in Scripture, the three kings Gaspar, Melchior and Balthasar are essential to Three Kings Day. The colonization of the Americas brought the tradition from Spain to the Americas. Now it is also celebrated in Spokane.
Hundreds of thousands of Russian Orthodox believers took a plunge into sub-zero waters across Europe on Thursday to wash off their sins as part of Epiphany feast day celebrations.
In many ways, I view Epiphany as paramount in the Advent Season. This is the date when Jesus is recognized and heralded as King of the Jews through the actions and recognition of pagans.
