If you post something on steemit that is not your material.

1. decline rewards and clearly state that you are posting for posterity and not rewards.
   This was clearly plagiarism to me because you didn't decline rewards. You didn't not give exact location that you copied the Popes words from. Nor did you show that the Vatican gave you permission to use them.
   Steemit is for posting your own content, commenting, discussing others point of view with a small amount of quotes sources stated.
   If you just want to post others content and earn rewards from that, you will be flagged.
