"And as soon as it was day, the elders of the people and the chief priests and the scribes came together, and led him into their council." (Luke 22:66)
The origin of "Good Friday" ceremonies are somewhat muddled in history. Some suggest that the earlier roots go back as far as 100 A.D., but others insist that it was well into the fourth century before anything like the "passion week" observances became established.
Beyond that, there is a good bit of controversy about the title itself. Everyone now agrees that the focus of the dedication is on the crucifixion of our Lord. So why "Good" Friday? Why not "Sad" Friday, or "Awful" Friday? Although historians and theologians tend to focus on the etymology of the term and debate the circumstances by which the ceremony became identified, the truth may well lie in the sovereignty of God Himself.
On that day in history, the sins of the world were paid for! This was the day that "it pleased the Lord to . . . make his soul an offering for sin" (Isaiah 53:10). That day, "the Lord hath laid on him the iniquity of us all" (Isaiah 53:6).
Yes, there was great sorrow and travail that day. During the awful physical darkness from noon to 3:00 p.m. (Matthew 27:45), Jesus had cried out in utter anguish: "My God, my God, why hast thou forsaken me?" (Matthew 27:46). The earth itself shook and rumbled as the creation was torn asunder in reaction to the horrific judgment of the Creator for sin (Matthew 27:51).
But then came the victory cry, "It is finished" (John 19:30), and, "Father, into thy hands I commend my spirit" (Luke 23:46). His suffering ended, the payment completed, eternal propitiation accomplished, Jesus laid down His human life to await the great resurrection that God might give "assurance unto all men, in that he hath raised him from the dead" (Acts 17:31).
