ROTFLOL!
It sure was furthering understanding when relics were brought in to replace the supernatural powers that ended after the Apostolic Era.
It sure was helpful when people were put to death, or condemned as heretics for having their own Bible.
It sure was helpful in furthering understanding when you insisted on Bibles only being in Latin and not native tongues.
Relics were used in the Apostolic Era; Acts chapter 19.
The verse about "supernatural powers ending" after the Apostolic Era is another verse that is found only in the Protestant Revised Version of the Bible. Actually, it must be in the Baptist Revised Version, because the Pentacostals certainly don't agree with it, do they?
