The Catholic Church is the Body of Christ, and consists of all Catholic Christians united under their Bishops, and ultimately under the Bishop of Rome - the Pope, the successor of St. Peter, currently Pope Francis. The Catholic Church consists of Our Blessed Lord, Jesus Christ, as its head; while its members consist of the Church Triumphant (all the saints in heaven), the Church Suffering (those who have died and are in purgatory), and the Church Militant (all those baptized Catholics on earth). The only difference is that the Catholic Church is the entire Body of Christ, while Catholics are members of that Body.
