The use of the terms "catholicism" and "catholicity" is closely related to the use of Catholic Church.
The earliest evidence of the use of that term is the Letter to the Smyrnaeans that Ignatius of Antioch wrote in about 108 to Christians in Smyrna.
Exhorting Christians to remain closely united with their bishop, he wrote: "Wherever the bishop shall appear, there let the multitude [of the people] also be; even as, wherever Jesus Christ is, there is the Catholic Church." From the second half of the second century, the word "catholic" began to be used to mean "orthodox" (non-heretical), "because Catholics claimed to teach the whole truth, and to represent the whole Church, while heresy arose out of the exaggeration of some one truth and was essentially partial and local".
Numerous other early writers including Cyril of Jerusalem (c.
, "universal doctrine") is a term which in its broadest sense refers to the beliefs and practices of Christian churches that understand and describe themselves as being Catholic within the universal and apostolic church.
The most frequent uses refer to the faith and practices of the Catholic Church, consisting of the Latin Church and 23 Eastern Catholic Churches in full communion with the Holy See of Rome, as understood by the Four Marks of the Church.
The New Jerusalem Bible (NJB) has become the most widely used Roman Catholic Bible outside of the United States.
The Revised Standard Version of the Bible, containing the Old and New Testaments, was published on September 30, 1952, and has met with wide acceptance.
The Revised Standard Version Bible seeks to preserve all that is best in the English Bible as it has been known and used through the years.
It is intended for use in public and private worship, not merely for reading and instruction.
They share certain features, although they also show some marked differences.
That they were regarded as a group at an early period is well attested. First John is more a homily than an epistle, since it has no opening address or closing salutation.
