Ecclesiology
Perhaps the most famous and most influential product of the council is the Dogmatic Constitution on the Church, Lumen Gentium.
In its first chapter, titled "The Mystery of the Church," is the famous statement that "the sole Church of Christ which in the Creed we profess to be one, holy, catholic and apostolic, which our Saviour, after His Resurrection, commissioned Peter to shepherd, and him and the other apostles to extend and direct with authority, which He erected for all ages as 'the pillar and mainstay of the truth.' This Church, constituted and organized as a society in the present world, subsists in the Catholic Church, which is governed by the successor of Peter and by the bishops in communion with him" (Lumen Gentium, 8). The document immediately adds: "Nevertheless, many elements of sanctification and of truth are found outside its visible confines."

so the pope and all the bishops are governed by ST PETER..."in communion with him"...NOT god or christ directly but st peter only.
