The Wycliffe Bible was translated from the Latin Vulgate, which is placed on the KJV-only view's line of claimed corrupt Bibles.
The Wycliffe Bible has many textual differences when compared to the Geneva Bible or the KJV. Some readings from the Latin Vulgate were added by Erasmus to his edited Greek NT text.
Are you unaware of the fact that there are actual significant textual differences including some involving whole verses in the pre-1611 English Bibles of which the KJV was a revision and the KJV?
Well, I was studying the line and read how the Waldensians teachings came into conflict with the Roman Catholic Church and declared heretical and subject to intense persecution; and one of the reason was their Bibles.
They were known as the Waldenses, or Vaudois, and concerning their antiquity and origin, Alexis Muston in his history on them, says:
"The Vaudois of the Alps are, in my opinion, primitive Christians, or descendants and representatives of the primitive church, preserved in these valleys from the corruptions successively introduced by the Church of Rome into the religion of the gospel. It is not they who have separated from Catholicism, but Catholicism which has separated from them by changing the primitive religion." History of the Waldenses, Vol. I, p. 17, 1875.
The noted Waldensian authority, William S. Gilly, M. A. states the same essential fact in these words:
"The terms, Vaudois in French, Vallenses in Latin, Valdesi, or Vallesi in Italian, and Waldenses in English ecclesiastical history, signify nothing more or less than Men of the Valleys; and as the valleys of Piedmont have had the honor of producing a race of people, who have remained true to the faith introduced by the first missionaries, who preached Christianity in those regions, the synonyms Vaudois, Valdesi, and Waldenses, have been adopted as the distinguishing names of a religious community, faithful to the primitive creed, and free from the corruption of the Church of Rome.
Long before the Roman Church, (that new sect, as Claude, Bishop of Turin in 840, called it,) stretched forth its arms, to stifle in its Antæan embrace the independent flocks of the Great Shepherd, the ancestors of the Waldenses were worshiping God in the hill countries of Piedmont, as their posterity now worship Him. For many ages they continued almost unnoticed." Waldensian Researches During a Second Visit to the Vaudois of Piemont, p. 6. London: Printed for C. J. G. & F. Rivington, 1831.
Speaking further of these relationships, he adds:
The Waldenses of Piemont are not to be regarded as the successors of certain reformers, who first started up in France and Italy at a time, when the corruptions of the Roman Church and priesthood became intolerable, but as a race of simple mountaineers, who from generation to generation have continued steadily in the faith preached to their forefathers, when the territory, of which their valleys form a part, was first Christianized. Ample proof will be given of this, as I proceed, and without attempting to fix the exact period of their conversion, I trust to be able to establish the fact, that this Alpine tribe embraced the gospel as it was first announced in all its purity, and continued true to it, in the midst of almost general apostasy. Nothing is more to be regretted than the mistakes which have been made upon this point, even by Protestant authors.
The country in which we find the earliest of these protesters is Italy. The See of Rome, in those days, embraced only the capital and the surrounding provinces. The diocese of Milan, which included the plain of Lombardy, the Alps of Piedmont, and the southern provinces of France, greatly exceeded it in extent. It is an undoubted historical fact that this powerful diocese was not then tributary to the papal chair...
Withstood Rome a Thousand Years
But the bishops in the region of Piedmont and the adjoining provinces did more than decline to go to Rome for ordination.
In the year 590, the bishops of Italy and the Grisons (Switzerland) to the number of nine, rejected the communion of the pope, as a heretic. Dr. Allixs Remarks on the Ancient Churches of Piedmont, chap. 5, p. 32, quoted in The History of the Christian Church, William Jones, chap. 4, sec. 1, p. 244.
About a century later, Paulinus, Bishop of Aquileia, in Italy, stood firmly against the domination and the innovations of the papacy, and was joined by other bishops in condemning the worship of images as idolatrous.
Turin, an important city a short distance to the west of Milan, was the center of an important diocese at the beginning of the ninth century. About the year 817 A. D. Claudius was appointed Archbishop of Turin, by Emperor Louis. Of him we read:
This man beheld with dismay the stealthy approaches of a power which, putting out the eyes of men, bowed their necks to its yoke, and bent their knees to idols. He grasped the sword of the Spirit, which is the word of God, and the battle which he so courageously waged, delayed, though it could not prevent, the fall of his churchs independence, and for two centuries longer the light continued to shine at the foot of the Alps. The History of Protestantism, J. A. Wiley, Vol. I, p. 21.
This is all supported by Lawrence, the learned essayist, who writes:
Here, within the borders of Italy itself, the popes have never been able, except for one unhappy interval, to enforce their authority. Here no Mass has been said, no images adored, no papal rites administered by the native Vaudois. It was here that Henry Arnaud, the hero of the valleys, redeemed his country from the tyranny of the Jesuits and Rome; and here a Christian church, founded perhaps in the apostolic age, has survived the persecutions of a thousand years. Historical Studies, Eugene Lawrence, p. 199.
Soon after the dawn of Christianity, they assert, their ancestors embraced the faith of St. Paul..."
"The Scriptures became their only guide; the same belief, the same sacraments they maintain today they held in the age of Constantine and Sylvester. They relate that, as the Romish Church grew in power and pride, their ancestors repelled its assumptions and refused to submit to its authority; that when, in the ninth century, the use of images was enforced by superstitious popes, they, at least, never consented to become idolaters; that they never worshiped the Virgin, nor bowed at an idolatrous Mass. When, in the eleventh century, Rome asserted its supremacy over kings and princes, the Vaudois were its bitterest foes. The three valleys formed the theological school of Europe. The Vaudois missionaries traveled into Hungary and Bohemia, France, England, even Scotland, and aroused the people to a sense of the fearful corruption of the church. They pointed to Rome as the Antichrist, the center of every abomination. They taught, in the place of Romish innovations, the pure faith of the apostolic age. Lollard, who led the way to the reforms of Wycliffe, was a preacher from the valleys; the Albigenses of Provence, in the twelfth century, were the fruits of the Vaudois missions; Germany and Bohemia were reformed by the teachers of Piedmont; Huss and Jerome did little more than proclaim the Vaudois faith; and Luther and Calvin were only the necessary offspring of the apostolic churches of the Alps.
