Sy,
I do understand what you are saying.

But I do want to point out that Emily was clear that she does not believe in the dogma of Purgatory so my reply was more in light of her honesty.
With that, and going back to Cam’s original post, Cam does believe in the need to pray for our dearly departed, which is in keeping with Catholic teaching. Therefore, I found a couple of novenas and made the suggestion that she also do a google search.
There is no sin in praying for the dead. We Catholics do it all.the.time.

The entire month of November is dedicated to the whole idea of it.
Whether Emily believes in Purgatory or not doesnt change the fact that it is Catholic dogma.
