"Why is it 'Good' Friday?" - Rev. Dr David A. Killian

Good Friday is the Friday before Easter Sunday. It's the day that Christians use to celebrate the day that Jesus Christ was killed on a cross, and it is a statutory holiday in many Western countries.

As Rev. Dr. David A. Killian from Brookline, Massachusetts says:
"What is 'good' about an innocent man being arrested in the middle of the night; betrayed by one of disciples, Judas; denied by another, Peter; accused falsely by the chief priests; mocked and scourged by soldiers; and condemned to death by the Roman Procurator, Pontius Pilate? What is 'good' about crucifixion as a criminal and being scorned and mocked in one's dying hours? What is 'good' about the crown of thorns on his head, the nails in his hands and feet? Yes, this is a good question, Why is Good Friday called Good ?"

There are different views on this, but the linguistic view is that it is the result of the changes to the English language over hundreds of years. One theory says that Good Friday was " Godes Friday", meaning "God's Friday". Another view is that "Good", used to be the same as "Great" or "Holy".
The spiritual view, as Rev. Dr. David A. Killian from Brookline, Massachusetts puts it, is that "Bad Friday" becomes "Good", "because God took the treachery, cruelty, and injustice of the crucifixion [on Good Friday] and transformed it into an expression of love, forgiveness and faithfulness" by bringing Jesus back to life on Easter Sunday.
