ELI5: Explain Like I'm 5

Corpus Catholicorum (series)

Okay kiddo, imagine you have a big toy box full of all kinds of toys. Now imagine that instead of toys, this box has lots and lots of old books.

Some of these books are about history, some are stories, some are about science, and some are about religion.

Now let's say you have to pick out all the books about the Catholic religion. To make it easier, you group all the books that belong to the same category together. These grouped books are called a series, and the series that has all the books about the Catholic religion is called the corpus catholicorum series.

This series is important because it helps people who are interested in the Catholic religion to find all the books they need without searching through the whole toy box. So it's like a special box within the big toy box just for Catholic books!
