Why is it called
Question: Why is two days before Easter Sunday called GOOD FRIDAY? What makes the day so great?
Answer: The time you mention is called GOOD Friday in some countries but is also referenced differently in other nations. In some places around the globe, the last workday of the week before Easter is prefixed with words such as Holy, Black, Great, Long and Silent.
What some people might find surprising is that the Bible is completely silent regarding any religious observance on the Friday before a believed resurrection of Jesus on Sunday morning (see our article "Three days and three nights" for more information). In fact, even the name of the day of the week Jesus was believed to be crucified on does not appear anywhere in the Bible. The ONLY day called by a given name in Scripture is the seventh day, which is the Sabbath. The names of the other days are first, second, third and so on.
A 1911 Encyclopedia states the following about this day.
This day was made as a fast day by the Roman Catholic Church in the 4th century A.D. (long after Jesus died). Its purpose is to commemorate the crucifixion and death of Jesus. The following is the Catholic Church's explanation.
