It has been devised that the Pope, bishops, priests, and monks are called the spiritual estate; princes, lords, artificers, and peasants, are the temporal estate. This is an artful lie and hypocritical device, but let no one be made afraid by it, and that for this reason:
I agree with this. From what Im understanding, Luther is saying that throughut the Roman society, humans seperated each other by class and important. If this is correct I agree when he says that Christians " are truy of the spiritual estate, and there is no differnece among them.."
