What if Protestantism in its present form is the fractured remains of a Catholic protest movement that began in 1517, but which has long since forgotten not only what it was protesting, but that it was formed by Catholics, in protest over conditions and practices within the Catholic Church? What if Protestantism has forgotten that its original intention was to return to full communion with the Catholic Church when certain conditions were satisfied?

The condition being "promote true doctrine"....

Few churches ever adopted the name “Protestant.” The most commonly adopted designations were rather “evangelical” and “reformed.” ... [W]hen the word Protestant came into currency in England (in Elizabethan times), its accepted significance was not “objection” but “avowal” or “witness” or “confession” (as the Latin protestari meant also “to profess”)....unfortunate as a name because it implies that Protestantism was mainly an objection. The dissenters in their own statement affirmed that “they must protest and testify publicly before God that they could do nothing contrary to His word.” The emphasis was less on protest than on witness.

"The condition being "promote true doctrine"...."

Great post. And, yes, this is the real condition necessary, a condition it appears as though they will never meet...unless God opens their eyes. But, we stand waiting.
