Textual criticism of the Greek New Testament attempts to come as near as possible to the original manuscripts (which did not survive), based on reconstructions from extant manuscripts of various ages and locales. Assessment of the individual manuscripts and their relationships to each other can produce a fairly reliable text from various readings that may have been the result of copying and recopying of manuscripts. It is not always age that matters. Older manuscripts may be corrupt, and a reading in a later manuscript may in reality be ancient. No single witness or group of witnesses is reliable in all its readings.

When Erasmus, the Dutch Humanist, prepared the Greek text for the first printed edition (1516) of the New Testament, he depended on a few manuscripts of the type that had dominated the church’s manuscripts for centuries and that had had its origin in Constantinople. His edition was produced hastily, he even translated some parts for which he did not have a Greek text from Jerome’s Latin text (Vulgate). In about 1522 Cardinal Francisco Jiménez, a Spanish scholarly churchman, published his Complutensian Polyglot at Alcalá (Latin: Complutum), Spain, a Bible in which parallel columns of the Old Testament are printed in Hebrew, the Vulgate, and the Septuagint (LXX), together with the Aramaic Targum (translation or paraphrase) of Onkelos to the Pentateuch with a translation into Latin. The Greek New Testament was volume 5 of this work, and the text tradition behind it cannot be determined with any accuracy. During the next decades new editions of Erasmus’ text profited from more and better manuscript evidence and the printer Robert Estienne of Paris produced in 1550 the first text with a critical apparatus (variant readings in various manuscripts). This edition became influential as a chief witness for the Textus Receptus (the received standard text) that came to dominate New Testament studies for more than 300 years. This Textus Receptus is the basis for all the translations in the churches of the Reformation, including the King James Version.

Large extensive New Testament critical editions prepared by the German scholars C. von Tischendorf (1869–72) and H. von Soden (1902–13) had Sigla (signs) for the various textual witnesses; they are complex to use and different from each other. The current system, a revision by an American scholar, C.R. Gregory (adopted in 1908), though not uncomplicated has made uniform practice possible. A more pragmatic method of designation and rough classification was that of the Swiss scholar J.J. Wettstein’s edition (1751–52). His textual apparatus was relatively uncomplicated. He introduced the use of capital Roman, Greek, or Hebrew letters for uncials and Arabic numbers for minuscules. Later, a Gothic P with exponents came into use for papyri and, in the few cases needed, Gothic or Old English O and T with exponents for ostraca and talismans (engraved amulets). Lectionaries are usually designated by an italicized lowercase l with exponents in Arabic numbers.

Known ostraca—i.e., broken pieces of pottery (or potsherds) inscribed with ink—contain short portions of six New Testament books and number about 25. About nine talismans date from the 4th to 12th centuries; they are good-luck charms with a few verses on parchment, wood, or papyrus. Four of these contain the Lord’s Prayer. These short portions of writing, however, are hardly of significance for a study of the New Testament textual tradition.

Texts and manuscripts

In referring to manuscript text types by their place of origin, one posits the idea that the major centers of Christendom established more or less standard texts: Alexandria; Caesarea and Antioch (Eastern); Italy and Gallia plus Africa (Western); Constantinople, the home for the Byzantine text type or the Textus Receptus. While such a geographical scheme has become less accurate or helpful, it still serves as a rough classification of text types.
