“Emerald Cross” Paschal Candle. The Paschal Candle tradition has its origins in early church and it is believed that St. Ambrose made this candle prominent during the Easter season late in the third century. The term “Paschal” comes from the word Pesach, which in Hebrew means Passover. The flame of the Paschal candle symbolizes Christ’s illuminating light, and his presence in the midst of his people.
