<P> The deuterocanonical books are considered canonical (that is, authoritative parts of the Bible) by Catholics, Eastern Orthodox, Oriental Orthodox, and the Church of the East, but they are considered non-canonical by most Protestants . </P> <P> The original usage of the term distinguished these scriptures both from those considered non-canonical and from those considered protocanonical . However, some editions of the Bible include text from both deuterocanonical and non-canonical scriptures in a single section designated "Apocrypha". This arrangement can lead to conflation between the otherwise distinct terms "deuterocanonical" and "apocryphal". </P> <P> Philip Schaff says that "the Council of Hippo in 393, and the third (according to another reckoning the sixth) Council of Carthage in 397, under the influence of Augustine, who attended both, fixed the catholic canon of the Holy Scriptures, including the Apocrypha of the Old Testament,...This decision of the transmarine church however, was subject to ratification; and the concurrence of the Roman see it received when Innocent I and Gelasius I (AD 414) repeated the same index of biblical books . Schaff says that this canon remained undisturbed till the sixteenth century, and was sanctioned by the council of Trent at its fourth session," although as the Catholic Encyclopedia reports, "in the Latin Church, all through the Middle Ages we find evidence of hesitation about the character of the deuterocanonicals...Few are found to unequivocally acknowledge their canonicity," but that the countless manuscript copies of the Vulgate produced by these ages, with a slight, probably accidental, exception, uniformly embrace the complete Roman Catholic Old Testament . </P> <P> The Council of Trent in 1546 supported the decisions about which books to include in the canon that were determined by earlier councils . While the majority at Trent supported this decision there were participants in the minority who disagreed with the books accepted in the canon . Among the minority, at Trent, were Cardinals Seripando and Cajetan, the latter an opponent of Luther at Augsburg . The Fathers in session at Trent confirmed the statements of earlier regional councils which also included the deuterocanonical books, such as the Council of Rome (382), the Synod of Hippo (393), the Council of Carthage (397 & 419) and the Council of Florence (1442) and provided "the first infallible and effectually promulgated pronouncement on the Canon" by the Roman Catholic Church . </P>
