The Church has certain marks by which it may be known, which are One, Holy, Catholic, and Apostolic. These marks are caused by the three attributes of authority, infallibility, and indefectibility. These attributes belong to the Church as a whole insofar as they follow from the Roman Pontiff in the See of Saint Peter, who holds them. Since we are living during an extended interregnum, answering the question of where the Church is is very difficult, because the Church is not visible anymore, since the marks by which it is made visible are lacking. That said, however, the Church still exists in the Soul of Christ, if not the Body of Christ, in those who hold to the Catholic Faith whole and entire and inviolate. More on this idea is to be found in this article.
