The Second Vatican Council had been considered by Pope Pius XII, but Blessed John XXIII actually called it. The Council was primarily a pastoral council to see how the church could deal with the needs of people in the 20th century. The Council did not change the language of the Mass, but allowed for certain parts (such as the readings) to be in the language of the people. Many of the changes that people associate with Vatican Council II such as the design of churches and, even Mass in the common language had been tried before the Council and were brought about by people in the church in opposition to what the documents actually call for. Ultimately, a Council is the work of the Holy Spirit, and so it is God's way of communicating things to us.
