[Sherman Logan]

Like all Restorationist movements they believe all other churches are in error. That there was a great apostasy and that the denomination Christ founded needed to be restored.

Pretty much the theory behind the original Protestants, FTM.

Not really. Luther and others set out to REFORM, not restore. Also, all of them accepted the place of Catholicism in the history of Christianity and while several (particularly Zwingli) sought a return to the Early Church, NONE of them believe that Christ set up a specific denomination that needed a full ‘restoration’.

Restoration groups have several things in common, all of which are outside protestantism. I can give you more detail if you like (its a current research topic of mine).
