Why do we call it ‘Good’ Friday?
Calling the day of the Crucifixion ‘Good’ Friday is a designation that is peculiar to the English language. In German, it is called
Karfreitag. The
Kar part is an obsolete word, the ancestor of the English word
care in the sense of
cares and woes, and it meant
mourning. So in German, it is Mourning Friday. And that is what the disciples did on that day—they mourned. They thought all was lost.
I’ve read that the word good used to have a secondary meaning of holy, but I can’t trace that back in my etymological dictionary. There are a number of cases in set phrases where the words God and good got switched around because of their similarity. One case was the phrase God be with you, which today is just good-bye. So perhaps Good Friday was originally God’s Friday. But I think we call it Good Friday because, in pious retrospect, all that tragedy brought about the greatest good there could be.
I can see virtue in either terminology. If we call it Mourning Friday, as in German, we are facing reality head on, taking up the cross if you will, fully conscious that the Christian walk is seldom a walk in the park. But if we call it Good Friday, as in English, we are confessing the Christian hope that no tragedy—not even death—can overwhelm God’s providence, love, and grace. Either way seems fine to me!

The source of our term for the Friday before Easter, "Good Friday," is not clear. It may be a corruption of the English phrase "God's Friday." It is the common name for the day among English- and Dutch-speaking people. It is a day that proclaims God's purpose of loving and redeeming the world through the cross of our Lord, Jesus Christ. It is a day that is good because God was drawing the world to God's self in Christ. As seen in John's gospel, particularly, God was in control. God was not making the best of a bad situation, but was working out God's intention for the world — winning salvation for all people. We call it "good" because we look backward at the crucifixion through the lens of Easter!
"Good Friday" is not a universal name for the day. The liturgical title for the day in the Western church was "Friday of Preparation," since the time Jews used the word paraskeue (getting ready) for Friday, meaning the "day of preparation." Popular names for the day are "Holy Friday" among the Latin nations, "Great Friday" among the Slavic peoples, "Friday of Mourning" in Germany, "Long Friday" in Norway, and "Holy Friday" (Viernes Santo) among Hispanic peoples.
