Timeline of Roman Catholic Doctrines in Church History

The Roman Catholic faith has been an evolution over many centuries. Catholics teach their faith was handed down from the Apostles and they only formally established these doctrines as the need arose yet a careful study of the writings of the church show that most of these doctrines were not held by the early church and were later additions. Events in red boldface are those pertaining to doctrine. The rest are historical events not directly related to RC doctrine.

TIMELINE

 [BV1]The Muratorian Canon was discovered by Italian historian Ludovico Muratori in the Ambrosian Library in northern Italy in 1749. The copy his discovered was written in Latin and dates to the 7^th or 8^th century. Internal evidence suggests an original version around AD 180.

 [BV3]The Council of Carthage listed the 27 books of the NT as well as the 39 books of the OT but included a few Apocryphal books such as Maccabees and Esdras. Prior to and after this council, most Christian and Jewish scholars held the Apocrypha to be non-canonical. They are omitted from the works of Philo, Origen, Melito of Sardis, Cyril of Jerusalem, Jerome, and Athanasius. They were also excluded at the Council of Laodicea held less than 40 years prior.

 [BV4]Trent declared both Scripture and tradition as authoritative. Salvation by grace alone through faith alone was rejected in favor of sacramental grace and righteousness based on an admixture of grace and works. The council also confirmed belief in transubstantiation. The council must be understood in its historical context. It has been called the anti-reformation council. Much of what it affirmed was in response to challenges coming from early Protestantism. The Apocryphal books contained support for doctrines such as prayers for the dead (purgatory) and indulgences.
