From the Prayer Book:
The Good Friday liturgy is the second part of the Triduum (the sacred three days). This most somber of all days is appropriately marked by fasting, abstinence, and penitence, leading us to focus on Jesus and the meaning of his Cross. Some churches do not use musical instruments or bells on this day. The church is often darkened. The bare, stark appearance of the church serves as a reminder of the solemnity and the sorrow of the day. The Lord of Life was rejected, mocked, scourged, and then put to death on the Cross. The faithful are reminded of the role which their own sin played in this suffering and agony, as Christ took all sin upon himself, in obedience to his Father’s will. By the Cross we are redeemed, set free from bondage to sin and death. The Cross is a sign of God’s never-ending love for us. It is a sign of life, in the midst of death.
God bless you,
