[Mark17]

Show us where any Protestants taught that the gospel was hopelessly lost until the Reformation.

I have been a Protestant since 1970, and this is the first time I have EVER heard this, so I doubt it is widespread among Protestants. I doubt it will cause many to swim the Tiber.

It’s never been taught in any Protestant church I’ve ever attended.

On the contrary, Protestants know about the Cathars and Wadensians and others who the RCC tortured and murdered for exposing it for the false gospel it teaches.

“I have been a Protestant since 1970, and this is the first time I have EVER heard this”

Really?

I used google for about 20 seconds and found these:

“The Reformation was, at its heart, a recovery of the true gospel of Jesus Christ, and this restoration had an unparalleled influence on churches, nations, and the flow of Western civilization.” http://www.ligonier.org/blog/reformation-and-men-behind-it/

“One person has defined Church History as the story of the loss and recovery of the Gospel. …It was apparent that the Gospel was nearly lost during the times of the Middle Ages.” http://www.solagroup.org/articles/faqs/faq_0034.html

“Tragically, this Patristic understanding was lost during the Medieval times and only recovered by Martin Luther and others at the time of the Reformation… As the study of Church History is the study of the loss and recovery of the Gospel…” http://www.solagroup.org/articles/understandingthebible/utb_0007.html

These took no time to find. Certainly less than 45 years.

It’s simply another one of those “projections” by Catholics.
