Codex Sinaiticus in the context of "Second Epistle to Timothy"

The Codex Vaticanus (The Vatican, Bibl. Vat., Vat. gr. 1209), is a manuscript of the Greek Bible, containing the majority of the Greek Old Testament and the majority of the New Testament. It is designated by siglum B or 03 in the Gregory-Aland numbering of New Testament manuscripts, and as δ 1 in the von Soden numbering of New Testament manuscripts. It is one of the four great uncial codices. Along with Codex Alexandrinus and Codex Sinaiticus, it is one of the earliest and most complete manuscripts of the Bible. Using the study of comparative writing styles (palaeography), it has been dated to the 4th century AD.

The manuscript became known to Western scholars as a result of correspondence between textual critic Desiderius Erasmus Roterodamus (known usually as Erasmus) and the prefects of the Vatican Library. Portions of the codex were collated by several scholars, but numerous errors were made during this process. The codex's relationship to the Latin Vulgate and the value Jerome placed on it is unclear. In the 19th century AD transcriptions of the full codex were completed. It was at that point that scholars became more familiar with the text and how it differed from the more common Textus Receptus (a critical edition of the Greek New Testament based on earlier editions by Erasmus).

The First Epistle to Timothy is one of three letters in the New Testament of the Bible often grouped together as the pastoral epistles, along with Second Timothy and Titus. The letter, traditionally attributed to the Apostle Paul, consists mainly of counsels to his younger colleague and delegate Timothy regarding his ministry in Ephesus (1:3). These counsels include instructions on the organization of the Church and the responsibilities resting on certain groups of leaders therein as well as exhortations to faithfulness in maintaining the truth amid surrounding errors.

Most modern scholars consider the pastoral epistles to have been written after Paul's death, although "a small and declining number of scholars still argue for Pauline authorship".

The Second Epistle to Timothy is one of the three pastoral epistles traditionally attributed to Paul the Apostle. Addressed to Timothy, a fellow missionary, it is traditionally considered to be the last epistle Paul wrote before his death. The original language is Koine Greek.

While the Pastorals are attributed to Paul, they differ from his other letters. Since the early 19th century, scholars have increasingly viewed them as the work of an unknown follower of Paul's teachings. This perspective arises from the fact that the Pastorals do not focus on Paul's typical themes, such as believers' unity with Christ, and they present a church hierarchy that is more organized and defined than what existed during Paul's lifetime.

In textual criticism of the New Testament, the Alexandrian text-type is one of the main text types. It is the text type favored by the majority of modern textual critics and it is the basis for most modern (after 1900) Bible translations.Over 5,800 New Testament manuscripts have been classified into four groups by text type. Besides the Alexandrian, the other types are the Western, Caesarean, and Byzantine. Compared to these later text types, Alexandrian readings tend to be abrupt, use fewer words, show greater variation among the Synoptic Gospels, and have readings that are considered difficult. That is to say, later scribes tended to polish scripture and improve its literary style. Glosses would occasionally be added as verses during the process of copying a Bible by hand. From the ninth century onward, most surviving manuscripts are of the Byzantine type.

The King James Version and other Reformation-era Bibles are translated from the Textus Receptus, a Greek text created by Erasmus and based on various manuscripts of the Byzantine type. In 1721, Richard Bentley outlined a project to create a revised Greek text based on the Codex Alexandrinus. This project was completed by Karl Lachmann in 1850. Brooke Foss Westcott and F. J. A. Hort of Cambridge published a text based on Codex Vaticanus and Codex Sinaiticus in 1881. Novum Testamentum Graece by Eberhard Nestle and Kurt Aland, now in its 28th edition, generally follows the text of Westcott and Hort.

Barnabas (/ˈbɑːrnəbəs/; Ancient Greek: Βαρναβᾶς; Syriac: ܒܪܢܒܐ), born Joseph (Ἰωσήφ) or Joses (Ἰωσής), was a prominent Christian disciple, identified as an apostle in Acts 14:14. According to Acts 4:36, he was a Cypriot Levite. He undertook missionary journeys as a companion of Paul the Apostle, evangelizing among the "God-fearing" Gentiles who attended synagogues in some of the Hellenized cities of Anatolia. He participated in the Council of Jerusalem (c. 49 AD).

Barnabas' story appears in the Acts of the Apostles, and Paul mentions him in some of his epistles. Tertullian named him as the author of the Epistle to the Hebrews, but this and other attributions are conjecture. The Epistle of Barnabas was ascribed to him by Clement of Alexandria and others in the early church and the epistle is included under his name in Codex Sinaiticus, the earliest extant manuscript of the complete New Testament. A minority of modern scholars concur with this traditional attribution

The great uncial codices or four great uncials are the only remaining uncial codices that contain (or originally contained) the entire text of the Bible (Old and New Testament) in Greek. They are the Codex Vaticanus in the Vatican Library, the Codex Sinaiticus and the Codex Alexandrinus in the British Library, and the Codex Ephraemi Rescriptus in the Bibliothèque nationale de France in Paris.

The Codex Alexandrinus (London, British Library, Royal MS 1. D. V-VIII) is a manuscript of the Greek Bible, written on parchment. It is designated by the siglum A or 02 in the Gregory-Aland numbering of New Testament manuscripts, and δ 4 in the von Soden numbering of New Testament manuscripts. It contains the majority of the Greek Old Testament and the Greek New Testament. It is one of the four Great uncial codices (these being manuscripts which originally contained the whole of both the Old and New Testaments). Along with Codex Sinaiticus and Vaticanus, it is one of the earliest and most complete manuscripts of the Bible. Using the study of comparative writing styles (palaeography), it has been dated to the fifth century.

It derives its name from the city of Alexandria (in Egypt), where it resided for a number of years before it was brought by the Eastern Orthodox Patriarch Cyril Lucaris from Alexandria to Constantinople (modern day Istanbul in Turkey). It was then given to Charles I of England in the 17th century. Bishop Brian Walton assigned Alexandrinus the capital Latin letter A in the Polyglot Bible (a multi-language version of the Bible with the different languages placed in parallel columns) of 1657. This designation was maintained when the New Testament manuscript list system was standardized by Swiss theologian and textual critic Johann J. Wettstein in 1751. Thus Alexandrinus held the first position in the manuscript list.

The Second Epistle of John is a book of the New Testament attributed to John the Evangelist, traditionally thought to be the author of the other two epistles of John, and the Gospel of John (though this is disputed). Most modern scholars believe this is not John the Apostle, but in general there is no consensus as to the identity of this person or group. (See Authorship of the Johannine works.)
