Upon becoming pope, John XXIII had plenty of energy and ideas. The Spirit was calling, and the pope, with a vision and hope and thinking of the past, present, and future, was going to answer this great call to the Church.
John — who today we call Pope Saint John XXIII — believed that Jesus’ love was for everybody in the world. He wanted the Church to be a strong voice proclaiming that love in modern times to modern people. His most famous encyclicals were Mother and Teacher (1961) and Peace on Earth (1963).
