Good Friday is the Friday before Easter Sunday and marks the date Jesus was crucified and died for our sins. The Octave of Easter extends from Easter Sunday to the following Sunday. White garments are worn by newly baptized and signify light, purity and joy. The tradition of the Easter Bunny was brought to America by German immigrants in the 1700's. The Easter bunny would visit children, hiding colored eggs that the Children had to find on Easter morning.
Easter is a convergence of three traditions.
Christian, Hebrew, and Pagan. Although the observance of Easter was at a very early period in the practice of the Christian church, a serious difference as to the day for its observance soon arose between the Christians of Jewish, and those of Gentile descent, which led to a long and bitter controversy. It was at the feast of the Passover in Jerusalem that Jesus, a Jew, was crucified and rose from the dead. There is no indication of the observance of the Easter festival in the New Testament, or in the writings of the apostolic Fathers. The sanctity of special times was an idea absent from the minds of the first Christians, who continued to observe the Jewish festivals, though in a new spirit, as commemorations of events which those festivals had foreshadowed.
