Textual critics like D. A. Carson assert that, "there is no unambiguous evidence that the Byzantine Text-type was known before the middle of the fourth century." However, the just is not true. Edward Miller was an accomplished textual historian living at the end of the nineteenth century. His exhaustive research showed that portions of Scripture distinctive to the Received Text were quoted extensively by notable church leaders as early as the second century and onward. (The Cause of The Corruption of The Traditional Text of the Holy Gospels; John Burgon and Edward Miller; P.64). Here are just a few specific examples of the leaders of the early church who support the readings or the Traditional or Received Text. I am indebted to Thomas M. Strouse, Ph.D. for the primary source material below.
The KJV -- Mark 1:1-2 "The beginning of the gospel of Jesus Christ, the Son of God; 2 As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee."
In Sinaiticus and Vaticanus it ways "In the Prophet Isaiah." The RV, ASV, RSV, NIV and 95% of all of the New Bibles read this way. But there is a problem. While Mark 1:3 is a quotation of Isaiah 40:3, verse 2 is a reference to Malachi 3:1. Therefore the KJV is right.
But what about the early church; is there any evidence that indicates whether the (erroneous) reading of the modern versions or the reading of the King James (which is based on the received text) is correct? The answer is yes. Irenaeus (130-202 A.D.) said this - "Mark does thus commence his Gospel narrative The beginning of the Gospel of Jesus, Christ, the Son of God, as it is written in the prophets. . . . Plainly does, the commencement of the Gospel quote the words of the holy prophets, and point out Him.., whom they confessed as God and Lord. " (Against Heresies III: 10:5, :11:4, :16:3)
Lets move on to another example. In my booklet called "The Great (?) Uncials" I told you that both Sinaiticus and Vaticanus omit Mark 16:9-20. Is there any support in the Early Church for this so called "longer ending" of Mark 16? Again we look to a sermon of Irenaeus (130-202 A.D.). The longer reading must have been in the New Testament he was using because he references Mark 16:19, So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God. KJV. This is what Irenaeus writes - "Also towards the conclusion of his Gospel, Mark says: So then, after the Lord Jesus had spoken to them., He was received up into heaven, and sitteth on the right hand of God." (Against Heresies 111:10:6)
Consider Luke 22:44, "And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground." There is the claim by those who hold the Critical Text Position that verses 43-44 did not exist before the Byzantine Era (the 4th or 5th centuries). It that true? The answer has to be NO! Why? Because Justin (100-165 A.D.), says, "For in the memoirs which I say were drawn up by His Apostles and those who followed them, it is recorded that His sweat fell down like drops of blood while He was praying, and saying, If it be possible, let this cup pass" (Trypho 103:24)
Next, I turn your attention to John 1:18 in the KJV. The verse says, "No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him." However, the NASB (New American Standard Bible) says "No man has seen God at any time; the only begotten God, who is in the bosom of the Father, He has explained Him."
The "older manuscripts" give us the reading of the NASB. This is a Gnostic perversion. They taught there were various levels of spiritual beings or lesser Gods between God and man. J. P. Green clearly identifies the problem. He says, Vaticanus "in John 1:18 refers to Christ as the only begotten God. How can anyone claim that one that is begotten is at the same time essential God, equal in every aspect to God the Father, and to God the Holy Spirit? This makes Christ to be a created Being. And it is a Gnostic twist given to the Bible by the heretic Valentinus and his followers, who did not regard the Word and Christ as one and the same; who thought of the Son of God and the Father as being one and the same Person. Therefore, they determined to do away with the only begotten Son in order to accommodate their religion. (Unholy Hands on the Bible edited by Jay. P. Green, Sr.; Sovereign Grace Publishers; p.12).
Since several of the oldest manuscripts like Vaticanus read "only begotten God" and since these are before the Byzantine era, that must be the correct reading, right? My answer again is no! Twice Irenaeus (130-202 A.D.), in referring to the passage says "the only begotten Son of God, which is in the bosom of the Father." (Against Heresies 111:11:6, (IV:20:6).
John 3:13 is the next passage to be considered. The KJV reads "And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven." I checked the NASB, NIV and the CEV leave this underlined phrase off. Others may as well. I did not check the other translations. But is there an early witness for the phrase the Son of man which is in heaven? Yes! Hippolytus (170-236 A.D.) in his sermon Against the Heresy of One Noetus says, And no man hath ascended up to heaven, but He that came down from heaven, even the Son of Man which is in heaven. (Against the Heresy of One Noetus I: 1:4)
John 5:3-4 in the KJV reads "In these lay a great multitude of impotent folk, of blind, halt, withered, waiting for the moving of the water. 4 For an angel went down at a certain season into the pool, and troubled the water: whosoever then first after the troubling of the water stepped in was made whole of whatsoever disease he had." These verses are omitted in the NIV, again on the basis that they are only in the "less important manuscripts." By that they mean again the "older" ones. However, Tertullian (160-221 A.D.) in one sermon On Baptism makes it clear that the passage was in the early manuscript that he was using for he says, "If it seems a novelty for an angel to be present in
waters, an example of what was to come to pass has forerun. An angel, by his intervention, was want to stir the pool at Bethsaida. They who were complaining of ill-health used to watch for him; for whoever had been the first to descend into them, after his washing ceased to complain." (On Baptism I: 1:5)
