The "good" in Good Friday

Kevin Williamson always includes "Words about Words" in his newsletter. This, today, was not technically in that section:

This week, Christians around the world will observe Good Friday, the most somber day on the liturgical calendar. The word good in Good Friday expresses an older sense of the adjective: holy, rather than desirable or positive. .... Good Friday is not an observance for the sort of person who insists he has “no regrets.” I don’t know what you do with somebody like that. But for people who understand, even if it is only at some instinctive level, the necessity of penance and reconciliation, Good Friday can be useful and purpose-giving, if not joyous. It isn’t only the joyous things that we need.
