สำหรับเรื่องของยิวผมไม่ค่อยเชี่ยวชาญนะครับ แต่สำหรับชาวคริสตชนคาทอลิก เรามีการฉลองครึ่งศตวรรษมาตั้งแต่ปี คศ.1300 (22 ก.พ.) โดยองค์สมเด็จพระสันตะปาปาโบนิเฟส ที่ 8 ครับ ถือว่าเป็นการเริ่มนับครั้งแรกของเรา และปีกึ่งศตวรรษล่าสุดที่เราได้ผ่านพ้นกันมาก็คือ ปี คศ.2000 ซึ่งอยู่ในสมณสมัยของสมเด็จพระสันตะปาปา จอห์น ปอล ที่ 2 ครับ
The "Great Jubilee" of 2000
The official logo of the Great Jubilee of 2000 features its motto: Christ Yesterday, Today, Forever.
Pope John Paul II announced a Great Jubilee for the year 2000 with his Apostolic Letter Tertio Millennio Adveniente (As the Third Millennium Approaches) of November 10, 1994. In this writing, he called for a three-year preparation period leading up to the opening of the Great Jubilee in December 1999. The first year, 1997, was to be dedicated to meditation on Jesus, the second to the Holy Spirit, and the third to God the Father. This Jubilee was especially marked by a simplification of the rites and the requirements for achieving the indulgence, as well as a huge effort to involve more Christians in the celebration.
Protestant Churches and the Orthodox were invited to celebrate the Jubilee together with the Catholics as a sign of ecumenical dialogue. Furthermore, special Jubilees were invoked for various groups within the Church, such as children, athletes, politicians, and actors. World Youth Day, celebrated in Rome in August, brought over two million young people together.
The Jubilee was closed by the pope on January 6, 2001, by the closing of the holy door of St. Peter's and the promulgation of the Apostolic Letter Novo Millennio Ineunte (Upon Entering the New Millennium), which outlined the pope's vision for the future of the Church.
