Introduction The Catholic Church (Latin: Ecclesia Catholica), also called the Roman Catholic Church (Latin: Ecclesia Catholica Romana), is the largest Christian church, with an estimated 1.28 to 1.41 billion baptized members worldwide as of 2026. It consists of 24 autonomous (sui iuris) churches. The largest one of these churches is the Latin Church. Besides it, there are 23 smaller Eastern Catholic Churches. Together, the Latin Church and Eastern Catholic churches are organized into nearly 3,500 dioceses and eparchies governed by bishops. Throughout history, the church has had a large role in the development of Western civilization. Catholic communities are present worldwide through missions, immigration, and conversions. The majority of Catholics live in the Global South, reflecting rapid demographic growth in Africa, Asia, and Latin America, as well as secularization in parts of Europe and North America. Catholic doctrine is rooted in the Nicene Creed and holds that the church is the "one, holy, catholic and apostolic Church" founded by Jesus Christ. It teaches that bishops are the successors of the apostles and that the pope—the bishop of Rome—is the successor of Saint Peter the Apostle, entrusted with a unique and primary pastoral role. Leo XIV is the current pope, serving as the head of the church; the Diocese of Rome forms his local jurisdiction, while the Holy See serves as the church's central governing authority through the Roman Curia. Apostolic teaching is understood to be transmitted through Scripture and sacred tradition, interpreted by the magisterium, the church's teaching authority. Catholic liturgical life includes the Roman Rite, other rites of the Latin Church, and the liturgical traditions of the Eastern Catholic Churches. Religious orders, monastic communities, and lay movements contribute to a wide range of theological and devotional expressions within Catholicism globally. Among the church's seven sacraments, the Eucharist is seen as the source and summit of the Christian life and is celebrated in the Mass. Catholics believe that through consecration by a priest, the bread and wine become the body and blood of Christ. The Virgin Mary is venerated as the Mother of God and honored through dogmas such as the Immaculate Conception, perpetual virginity, and Assumption, including devotional practices. Catholic social teaching emphasizes care for the poor, the sick, and the marginalized. The church operates tens of thousands of educational, medical, and charitable institutions worldwide, making it the largest non-governmental provider of education and health care. (Full article...) Selected 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 image  Credit: Anne de Felbrigge The Felbrigge Psalter is an illuminated manuscript Psalter from mid-thirteenth century England that has an embroidered bookbinding which probably dates to the early fourteenth century.The embroidery is worked in fine linen with an illustration of the Annunciation on the front cover and an illustration of the Crucifixion on the back. Selected biography  Asser (d. 908/909) was a Welsh monk from St. David's, Dyfed, who became Bishop of Sherborne in the 890s. In about 885 he was asked by Alfred the Great to leave St. David's and join the circle of learned men which Alfred was recruiting for his court. After spending a year at Caerwent due to an illness, he accepted. In 893 Asser wrote a biography of Alfred, called the Life of King Alfred. The manuscript survived to modern times in only one copy, which was part of the Cotton library. That copy was destroyed in a fire in 1731, but transcriptions that had been made earlier, allied with material from Asser's work that was included by other early writers, have enabled the work to be reconstructed. The biography is now the main source of information about Alfred's life, and provides far more information about Alfred than is known about any other early English ruler. Asser also assisted Alfred in his translation of Gregory the Great's Pastoral Care, and possibly with other works. Asser is sometimes cited as a source for the legend of Alfred having founded the University of Oxford, which is now known to be false. A short passage making this claim was interpolated by William Camden into his 1603 edition of Asser's Life. Doubts have also been raised periodically about whether the entire Life is a forgery, written by a slightly later writer, but it is now almost universally accepted as genuine.
