On 11 October 1962 Pope Roncalli opened the Second Vatican Council in St. Peter's, indicating a precise orientation of goals: not defining new truths or condemning errors, but: renewing the Church to make it holier and therefore more suitable for announcing the Gospel to contemporaries ; to seek ways for the unity of Christian churches; to detect what is good in contemporary culture by opening a new phase of dialogue with the modern world, seeking above all "what unites instead of what divides".
