A good way to assist the Holy Souls in Purgatory is to have Masses offered for them through: Aid to the Church in Need. You can contact them at:
Having Masses offered through this organization is a good way of multi-tasking. You assist the Holy Souls in Purgatory, you support priests in poor areas of the world. The Mass offerings go much further than they would in a developed country.
For instance the recommended minimum Mass offering in some areas of Australia is $10 (Australian currency). In Australia this does not go very far, but in a third world country I have been told that it can buy a large sack of rice and feed many people for a week. The people in these third world areas are usually so poor that they can hardly support themselves, yet alone the local priest, going back to the theme of multi-tasking, you are supporting the building up of the Catholic Church in these areas and are in the process fulfilling one of your important obligations as a baptized Catholic.
You are also building up these communities with their education, infrastructure, health and housing and protecting them from the threat of communism (which will promise them the world and will deliver them misery) and are ensuring that they stay Catholic and not join some other religious denomination. In South American countries, poor Catholics are being diverted in droves into other religious dominations that have lots of financial backing.
You can also ask the Holy Souls for necessary favours as well, perhaps for conversions and for an end to the culture of death. This last petition is an ever increasing need. On the TV news last night there was a very unwell man who is planning to go to Switzerland to end his life, because thankfully Euthanasia (murdering yourself) is illegal in Australia, although there are definite pushes to have it legalized.
I muted the sound of this manipulative TV news item so that my children could not be affected by it and told them that this man probably has someone encouraging him to do this. I had a particular Australian doctor in mind who we refer to here as “Dr Death”. I don’t know why he is not put in jail. Then the camera angle changed and sure enough there was the doctor that I had in mind. He was behind this unwell man urging him to end his life, just as he had urged others to do so. Unfortunately some of them have listened to him and have ended their lives. Please pray for the conversion of this doctor.
