Is 1John 5:7 in KJV a forgery?????

Is 1John 5:7 in  KJV a forgery?????

1Jn 5:6 This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth. 
1Jn 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.  
1Jn 5:8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one. 

King James Version based bibles and 8 of the later Greek and many Latin versions of New Testament contains the Passage. Here is a humble study about this controversy.... Please be guided by Holy Spirit not by the prejudice.

 I can confirm that this is a clear addition to the Holy Scripture.. Here are the reasons for this. As it is a vast subject I give just an abstract of the main points. 

• This 1John5:7, known as  the Comma Johanneum, is not present in any of the original Greek manuscripts. It present only in Latin scripts and only eight of the later Greek Scripts.

1.  Codex Montfortianus, dating from the early sixteenth century. 
2.  A variant reading in a sixteenth century hand, added to the fourteenth-century codex Regius of Naples. 
3. A variant reading added to a tenth-century manuscript in the Bodleian Library at Oxford. 
4. A variant reading added to a sixteenth-century manuscript at Wolfenbüttel. 
5.  A fourteenth or fifteenth century manuscript in the Vatican. 
6.  A variant reading added to a sixteenth-century manuscript at Naples. 
7. A sixteenth-century manuscript at the Escorial, Spain. 
8.  An eighteenth-century manuscript, influenced by the Clementine Vulgate, at Bucharest, Rumania. 

• Clement of alexandria (AD200): He never used this Passage. This passage is absent from an extant fragment of Clement of Alexandria (c. 200), through Cassiodorus (6th century), with homily style verse references from 1 John, including verse 1 John 5:6 and 1 John 5:8 without verse 7, the heavenly witnesses. 
• Tertullian(AD 160-225): He was engaged in the Trinity- Arian-Sabellian controversies but never used this passage to prove Trinity. If this word were existed during his time, he would have used to defend Arianism. He used even John 10:30, " I and my Father are ONE" but never used 1John 5:7. 
• Jerome(AD 347-420): The Catholic Encyclopedia of 1910 asserts that Jerome "does not seem to know the text". This is based on the theory that the Vulgate Prologue. is not from Jerome. [Ref: Catholic Encyclopedia Vol 8 of 15, Epistles of St John, Walter Drum, 1910 p. 435-438, Chief Editor Charles George Herbermann. Online HTML for this section of the Catholic Encyclopedia at newadvent.org.] 
•  NONE of the Greek fathers used this word even during Trinity-Arianism-Sabellianism controversies. 
• The passage is absent from the manuscripts of all ancient versions (Syriac, Coptic, Armenian, Ethiopic, Arabic, Slavonic), except the Latin; and it is not found (a) in the Old Latin in its early form (Tertullian Cyprian Augustine), or in the Vulgate (b) as issued by Jerome (codex Fuldensis [copied a.d. 541-46] and codex Amiatinus [copied before a.d. 716]) or (c) as revised by Alcuin (first hand of codex Vallicellianus [ninth century]). 

 The most important thing is that this passage is an absolute extra fitting to the whole idea of the chapter. John was telling about the testimonies of water, Spirit and blood for Jesus in 5:6 in separate sentences and it is clear that he put everything clear in the next verse. and there is no reason for the early church fathers to omit this passage from old Greek manuscripts. Omitting the truth and adulteration to the Scripture are equally punishable. Rev 22:18 "For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:" Here is the link for the Adam Clarke's commentary on 1John 5. Please spare some moments to read it.

 None of the people mentioned here are unitarians or Oneness pentacostalists[They might have not existed during that period]. All are genuine trinitarians. Please find the truth. I hope and pray that you may be guided not by the prejudice but by the Holy Spirit.
