Jubilee in the Catholic Church

A jubilee is a special year of remission of sins, debts and universal pardon. In the Book of Leviticus, a jubilee year is mentioned as occurring every 50th year (after 49 years, 7×7, as per Leviticus 25:8) during which slaves and prisoners would be freed, debts would be forgiven, and the mercies of God would be particularly manifest.
