The four last things are death, judgement, heaven and hell, of which only one is certain: the first. Death is the key to the four last things, and thinking about death is the key to the devotion based on the four last things which flourished in a small way at various times and places during the middle ages, and in a changed form in counter-reformation Europe.
Here I am not writing about the last things themselves, but about the devotion, and, even then, not about the counter-reformation devotion, which was part of a different world from the one in which the mediaeval devotion flourished, and had a completely different significance. I want to look at the four last things in the middle ages, as one devotional subject with the emphasis changing from one to another of its constituent parts so that it acted as a barometer for the mood and atmosphere in the Church.
In the last twenty years or so thinking on the four last things has had something of a revival and has, I believe, again been reflecting the Church’s current moods, though in traditional style.
Possibly the most noticeable feature of this devotion, or subject for contemplation, is that it has only been really popular when the religious atmosphere has been restless and when there has been criticism of the established Church to the point of disillusionment. Its popularity has also been related to concern for the individual soul. It has only been in the last few years that theologians have tried to combine communal and personal salvation in a devotion on the four last things.
