Jubilaeum Maximum (May 26, 1949) is a Papal bull of Pope Pius XII to announce a Holy Year for 1950. Pope Pius XII invites all faithful to the Eternal City of Rome to celebrate a Holy Year, to change and sanctify one’s life. A renaissance of humanity is possible, if all people turn away from earthly secular things to things eternal. Public life must respect the commandments of Christ. The world needs to be changed according to the spirit of His gospel. The Catholic bishops are asked to redirect the faithful to this end, whether in Rome or at home.
