Catholic Church
The Catholic Church refers to the universal church, or Christian Church. Catholic (from Greek: καθολικός, romanized: katholikos, lit. 'universal') was first used to describe the church in the early 2nd century. The term is used to refer to the unity of the church that surpasses ecclesiastical, linguistic, cultural, and liturgical boundaries, which are constructed by humans. Christians of every background are united to Christ's One Holy Catholic and Apostolic Church by baptism.
Catholic Creeds
The Apostles' Creed, the Nicene Creed, and the Athanasian Creed, due to their historicity and universal reception in the Early Church, are often called the Catholic Creeds, as symbols and confessions of Christ's Catholic Church, rather than as representing one church or denomination alone.
