Good Friday falls on the last Friday before Easter... It 's a day to show humility and reverence....many Christians observe this as a day of prayer and fasting...Crosses and chairs may be draped in black.... During Holy week, you will often see a cross either inside a church or outside draped in black or purple cloth.... The service of worship is traditionally offered between noon and 3:00 p.m., the time that coincides with the hours that Jesus hung on the cross... Good Friday is not a holiday but a religious observance,most Christian have to work and are only available to attend an evening service. Good Friday evening services are commonplace in the black church.Often used as a somber processional for the Good Friday Service, the hymn “Calvary “is effective in helping sustain a reflective meditative mood. Ministers are traditionally robed in black for this service. This song identifies with the suffering of Christ...I love Richard Smallwood version of Calvary.
