The rebuttal by Dr. Robert Stackpole is respectful and convincing. I hope visitors here will take the time to read it, but I'll summarize a few points:
- Translations of Sr. Faustina's work was originally smuggled out from behind the iron curtain.
- The Italian translation of the work was faulty and the original documents couldn't be reviewed as long as the Communists ruled Poland. This lack of the original documents and mistranslations led to the condemnation and ban prior to Poland opening up.
- Once the original documents were available and analyzed, the ban was lifted by the same Congregation that imposed the ban.
- Criticism of the Divine Mercy image for not showing the Sacred Heart of Jesus ignores all the sacred images that do not show Christ's heart including the crucifix, images of the Resurrection, icons of Christ, etc.
- Devotion to the Sacred Heart and the Divine Mercy devotion are complementary.
The website where I found Dr. Stackpole's article is a wealth of information on the Divine Mercy devotion and I plan to spend some time there. (Catholic Culture gives them a good rating.)
I could just take the original post down, but I think in our confusing times people need to know the reasons something is wrong. If you can address the errors in an argument, you have a much better chance of protecting others who might be influenced by it.
