Jubilee in Catholicism
The jubilee is a solemnity of the Catholic Church, today held every 25 years. For special reasons the pope can celebrate extraordinary jubilees, where he grants remission of the temporal punishment due for mortal sins already forgiven in confession.
The origin of the jubilee is biblical, as you can see in Leviticus 25:1-17. The year of jubilation opens with the sound of the trumpet, called in Hebrew “jobel”, hence the name jubilee. The old legislation provided for the practice of freeing the slave and returning property every seven years. The new legislation declared holy the fiftieth year in which liberation was proclaimed for all residents of the country. It will be the year of joy, where they will not sow. It will be a sacred year and they will eat what the field produces.
