"It is the purpose of this book to show that, although free church groups in ancient and medieval times sometimes promoted doctrines and practices agreeable to modern Baptists, when judged by standards now acknowledged as baptistic, not one of them merits recognition as a Baptist church. Baptists arose in the seventeenth century in Holland and England. They are Protestants, heirs of the Reformers." (ibid, page 2, emphasis mine)
The following is adapted from McGoldrick's chapter on the Waldenses of the 12th and 13th centuries which examines their origins and founder Peter Waldo, their explicit Catholic doctrines and beliefs, a short account of their history, and where they are today (hint: they did later become a Protestant sect, but were never "baptistic" in belief).

WHAT ABOUT THE WALDENSES?
The same period of Medieval history that saw the rise and suppression of the Cathars witnessed the emergence of a very different religious movement known as the Waldenses. In contrast to the Cathars, whose dualistic world- and life-view placed them in radical opposition to historic Christianity, the Waldenses began as a reform movement within the Roman Catholic Church and never imbibed Manichaean teachings.
PETER WALDO : Founder of the Waldenses
The sect owed its origin to Peter Waldo (d. 1216), known in France as Valdes. Little is known about Waldo's life, but it is clear that he was a prosperous merchant in Lyons who suddenly divested himself of his wealth in order to pursue a life of "evangelical perfection," which, to medieval Catholics, meant following the example of Christ, including the Savior's poverty.
The sources indicate that Waldo became impressed with his need to follow Christ when he heard a minstrel relate the legend of St. Alexis, who had renounced riches and separated from his wife to undertake a pilgrimage to the Holy Land. Waldo also accepted counsel from a priest who told him of Christ's command to a rich inquirer who had come to him seeking the way to eternal life. Jesus said:
"If you want to be perfect, go, sell your possessions, and give to the poor, and you will have treasure in heaven. Then come, follow me." (Matthew 19:21)
His personal appropriation of the Lord's teaching to the rich young man mentioned in the Gospel reflects Waldo's habit of accepting biblical injunctions literally, and it shows his great desire to conform his life to the teachings of Christ. Waldo developed a sense of urgency to become learned in the scriptures, and to that end he paid two scholars to translate the Gospels and other portions of the Bible into his vernacular tongue.
While the behavior Waldo exhibited was unusual, it was not unprecedented, and his actions to this point did not violate the canons of the Roman Catholic Church. Vows of poverty and the study of scripture had been regular features of monastic living for centuries and enjoyed the approval of the Church. Waldo, however, was neither a monk nor a priest, but a devout layman who sought to practice "evangelical perfection" without entering a monastery. To those who ridiculed him for this, Waldo explained,
"Citizens and friends, I am not out of my mind, as you seem to think, but I am avenging myself on those who are oppressing me in making me a lover of money more than God. This act I do for myself and for you: for me, so that if from now on I possess anything you may call me a fool; for you, in order that you, too, may be led to put your hope in God and not in riches." [1]
WALDENSES UNAUTHORIZED PREACHING
Recruits to Waldo's "Poor of Lyons" came from all levels of society. A few were priests, but most were laymen. Durand of Huesca (Spain), a scholar of some ability, became unofficial theologian for the movement, but the emphasis of these "Waldenses" was, from the start, on personal piety and good works performed in imitation of Christ and the apostles.
The movement did not seek to alter Catholic dogma and was not intended to be a separatist church. The bishops at first would have found nothing about which to object had not the Waldenses assumed the right to preach. It was unauthorized preaching in public places that aroused suspicion and led the Archbishop of Lyons to attempt to stop them.
Waldo and his disciples were ordered to submit to the bishops. To render unqualified submission would, however, have meant the end of their preaching, so the Waldenses disobeyed and brought upon themselves a barrage of clerical criticism. As of yet the Waldenses had issued no pronouncements which could have been rightly construed as heresy, and in 1180 Waldo signed a statement of faith dictated by a papal legate in which the popular exponent of apostolic living subscribed to all of the major tenets of traditional Catholicism. [2]
While Waldo and his followers had no doctrinal quarrel with Rome, their defiance of episcopal prohibitions against preaching led in 1184 to their condemnation by a synod of bishops meeting in Verona. Much to their dismay, the Waldenses were excluded from the Church and declared to be heretics.

Zenas is right, one can see a credible Baptist historian in McGoldrick. I think it's hilarious!
