Before printing from movable type became common (from the 15th century C.E. onward), the original Bible writings and also copies of them were handwritten. Therefore, they are called manuscripts (Latin, manu scriptus, “written by hand”). This is an Account of the history of the Greek text up to the time of the Printed Text of the Greek New Testament. It, of course, covers Desiderius Erasmus, his life and the Greek Text he produced that attained wide acceptance for centuries until 1881.
MODERN textual scholars do not hesitate to omit from the Bible the spurious passage found at 1 John 5:7-8. It is omitted by the translations ERV, ASV, RSV, ESV, NASB, LEB, CSB, UASV, etc.) Commenting on these words, the greatest textual scholar of the 20th century Bruce M. Metzger said, "these words are spurious and have no right to stand in the New Testament is certain ..." - Textual Commentary on the Greek New Testament (1994), 647.
When you open your Bible today, can you be confident that the words you are reading are, in fact, the very corresponding English words that were written by Matthew, Mark, Luke, John, Peter, Paul, James, and Jude nearly 2,000 years ago? Confident, you say? Just how confident are you? Are you confident because of what you know or what you hear?
The most commonly used and referred to Textus Receptus today is the 1550 Stephanus New Testament (TR1550)
The biblical Textus Receptus constituted the translation-base for the original German Luther Bible, the translation of the New Testament into English by William Tyndale, the King James Version, the Spanish Reina-Valera translation, the Czech Bible of Kralice, and most Reformation-era New Testament translations.
We have textual traditions, or families of texts, which grew up in a certain region. For example, we have the Alexandrian text-type, which Westcott and Hort called the Neutral text that came from Egypt. Then, there is the Western text-type, which came from Italy and Gaul as well as North Africa and elsewhere. There was also the Caesarean text-type, which came from Caesarea and is characterized by a mixture of Western and Alexandrian readings. The Byzantine text-type, also called the Majority Text, came from Constantinople (i.e., Byzantium).
