Task: Question Generation
Input (English): He reminded the council fathers that only a few years earlier Pope Pius XII had issued the encyclical Mystici corporis about the mystical body of Christ. He asked them not to repeat or create new dogmatic definitions but to explain in simple words how the Church sees itself. He thanked the representatives of other Christian communities for their attendance and asked for their forgiveness if the Catholic Church is guilty for the separation. He also reminded the Council Fathers that many bishops from the east could not attend because the governments in the East did not permit their journeys.
Output (English): What edict did Pope Pius XXIII issue regarding the body of Christ?
