Catholic Church History
The Roman Catholic Church, officially known as the Catholic Church, is the world's largest Christian church, and represents over half of all Christians and one-sixth of the world's population. It is made up of one Western church (the Latin Rite) and 22 Eastern Catholic churches, divided into 2,782 jurisdictional areas around the world. The Church looks to the Pope, currently Pope Benedict XVI, as its highest visible authority in matters of faith, morality, and Church governance. The Church community is composed of an ordained ministry and the laity. Both groups may become members of religious communities such as the Dominicans, Carmelites, Jesuits, and others.
The Catholic Church defines its mission as spreading the message of Jesus Christ, found in the four Gospels, administering sacraments that aid the spiritual growth of its members, and the exercise of charity. To further its mission, the Church operates social programs and institutions throughout the world. These include schools, universities, hospitals, missions, and shelters, as well as Catholic Relief Services and Catholic Charities that help the poor, families, the elderly, and the sick.
Through Apostolic succession, the Church believes itself to be the continuation of the Christian community founded by Jesus in his consecration of Saint Peter. The Church has defined its doctrines through various ecumenical councils, following the example set by the first Apostles in the Council of Jerusalem. Catholic faith is summarized in the Nicene Creed and detailed in the Catechism of the Catholic Church. Formal Catholic worship is ordered by the liturgy, which is regulated by Church authority. The celebration of the Eucharist, one of seven Church sacraments and a key part of every Catholic Mass, is considered the center of Catholic worship.
From at least the 4th century the Catholic Church has played a prominent role in the history of Western civilization. In the 11th century, the Eastern Orthodox Church and the Western, Catholic Church split, largely over disagreements regarding papal primacy. Eastern churches which maintained or later re-established communion with Rome now form the Eastern Catholic Churches. In the 16th century, partly in response to the Protestant Reformation, the Church engaged in a substantial process of reform and renewal, known as the Counter-Reformation.
The Catholic Church believes that it is the "one, holy, catholic, and apostolic church" founded by Jesus, but acknowledges that the Holy Spirit can make use of Christian communities separated from itself to bring people to salvation. The Church teaches that it is called by the Holy Spirit to work for unity among all Christians—a movement known as ecumenism. Modern challenges facing the Church include the rise of secularism, and opposition to its pro-life stance on abortion, contraception, and euthanasia.
