Aquinas and Augustus of Hippo, both proposed this extraordinary idea that babies who were unbaptised would not know heaven. They also proposed the idea of purgatory which doesn’t exist in The Bible. There’s absolutely no evidence for it. However, what an extraordinary brilliant coup to imagine such a thing as purgatory. That a soul needs to be prayed for, in order to go to heaven. In order to turn left when he enters the aeroplane of heaven and get a first class seat. That, he needs to be prayed for. And many hundreds, indeed over a thousand years, you’ll be amazed what generous terms those prayers came at. Sometimes as little as two thirds of a year’s salary. Could ensure that a dead loved one would go to heaven. And money could ensure that your baby. Your dead child, your dead uncle, your dead mother, could go to heaven. And if you were rich enough, you could have a chantry built and monks would permanently sing prayers so that that existence in heaven for the child would go up and up and up until they were at the table of the Lord themselves.
