Introduction

The Catholic Church (Latin: Ecclesia Catholica), also known as the Roman Catholic Church, is the largest Christian church, with 1.27 to 1.41 billion baptized Catholics worldwide as of 2025. It is among the world's oldest and largest international institutions and has played a prominent role in the history and development of Western civilization. The Church consists of 24 sui iuris (autonomous) churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies around the world, each overseen by one or more bishops. The pope, who is the bishop of Rome, is the chief pastor of the church.

The core beliefs of Catholicism are found in the Nicene Creed. The Catholic Church teaches that it is the one, holy, catholic and apostolic church founded by Jesus Christ in his Great Commission, that its bishops are the successors of Christ's apostles, and that the pope is the successor of Saint Peter, upon whom primacy was conferred by Jesus Christ. It maintains that it practises the original Christian faith taught by the apostles, preserving the faith infallibly through scripture and sacred tradition as authentically interpreted through the magisterium or teaching office of the church. The Roman Rite and others of the Latin Church, the Eastern Catholic liturgies, and communities and societies such as mendicant orders, enclosed monastic orders, third orders and voluntary charitable lay associations reflect a variety of theological and spiritual emphases in the church.

Of its seven sacraments, the Eucharist is the principal one, celebrated liturgically in the Mass. The church teaches that through consecration by a priest, the sacramental bread and wine become the body and blood of Christ. The Virgin Mary is venerated as the Mother of God, and Queen of Heaven; she is honoured in dogmas, such as that of her immaculate conception, perpetual virginity and assumption into heaven, and devotions. Catholic social teaching emphasizes voluntary support for the sick, the poor and the afflicted through the corporal and spiritual works of mercy. The Catholic Church operates tens of thousands of Catholic schools, universities and colleges, hospitals and orphanages around the world, and is the largest non-governmental provider of education and health care in the world. Among its other social services are numerous charitable and humanitarian organizations. (Full article...)

The First Council of Nicaea, held in Nicaea in Bithynia (present-day İznik in Turkey), convoked by the Roman Emperor Constantine I in 325, was the first Ecumenical council of the Christian Church, and most significantly resulted in the first uniform Christian doctrine, called the Nicene Creed. With the creation of the creed, a precedent was established for subsequent 'general (ecumenical) councils of Bishops' (Synods) to create statements of belief and canons of doctrinal orthodoxy— the intent being to define unity of beliefs for the whole of Christendom.The purpose of the council was to resolve disagreements in the Church of Alexandria over the nature of Jesus in relationship to the Father; in particular, whether Jesus was of the same substance as God the Father or merely of similar substance. St. Alexander of Alexandria and Athanasius took the first position; the popular presbyter Arius, from whom the term Arian controversy comes, took the second.

Selected biography



Thomas Aquinas, O.P. (also Saint Thomas Aquinas, Thomas of Aquin, or Aquino; c. 1225 – 7 March 1274) was an Italian Catholic priest in the Order of Preachers (more commonly known as the Dominican Order), a philosopher and theologian in the scholastic tradition, known as Doctor Angelicus, Doctor Universalis and Doctor Communis. He was the foremost classical proponent of natural theology, and the father of the Thomistic school of philosophy and theology. Aquinas is held in the Catholic Church to be the model teacher for those studying for the priesthood (Code of Canon Law, Can. 252, §3). The works for which he is best-known are the Summa Theologica and the Summa Contra Gentiles.
