Pope Paul VI continued the Second Vatican Council that was convened under Pope John XXIII. One of the key documents from Vatican II was Gaudium et Spes, which addressed the Catholic Church's relationship with modern society and issues like economics, poverty, social justice, culture, science, and ecumenism. The document affirmed human dignity and promoted improved relations with other Christian faiths and people of other religions. It emphasized that the Church should serve all people by helping reveal God's message and make his life visible in the world.
