"It is true that the Divine love which overwhelms the soul gives, as I think, a peace greater than that which can be expressed, yet this peace does not in the least diminish her pains, nay, it is love delayed which occasions them, and they are greater in proportion to the perfection of the love of which God has made her capable."
- Treatise on Purgatory (Chapter 12, page 318)
http://www.helpersoftheholysouls.com/ourpatron_plus/purgatory_saints/StCatharineOfGenoa.htmMalleus, our knowledge and belief about the souls in Purgatory come from the Church and the saints help us to feed that desire to do God's Will in what the Church teaches.
Besides there are many other saints who inspire us to come to the aid of the holy souls. So if you are having trouble with St Catharine of Genoa you should move on. Don't let any one saint whom
you think is not in conformity to the general belief of the Church become larger than she is in reality. Put her on the backburner, as it were, and maybe when you are more mature in the Faith, it will all fall into place.
God bless you.
