>>About when did the occasion of Jesus' death become commonly known with the ecclesiastical term, "Good Friday", and what where the reasons cited as it being "Good"?
"Good Friday" is a term that is mostly used among English speaking Christians. Otherwise, the day is called "Preparation Day" (see Mk 15:42) in the Roman Missal, the "Holy and Great Friday" in the Greek liturgy, and "Sorrowful Friday" among most Germans. Sometimes too, the day was called "Long Friday" by the Anglo-Saxons; so today in Denmark.
Linguistically, the origin of the term "Good" is not clear. Some say it is from "God's Friday"; others maintain that it is from the German Gute Freitag, and not specially English. The American Heritage® Dictionary of the English Language, Fourth Edition, 2000, gives the etymology as "from good, pious, holy (obsolete)".
Theologically speaking, there is no shortage of reasons why we may call the day "good", and all these reasons have to do with the benefits we derive from all that our Savior Jesus Christ endured and underwent in our place on that day of his crucifixion, death, and burial.<<
