There is an interesting term called the “black box theory”. It speaks about an object which can be analyzed in terms of its input and output, but there is no knowledge of its internal workings. Many of us probably don’t know that in the Congregation of the Resurrection Archives in Rome there are more than 200 black boxes. Fr. Paul Szymanowski, CR is in Rome going through and digitizing the archives, and periodically he shares some of the Black Box contents with us.
The most recent black box is about the Sisters of the Resurrection, you can see the contents by clicking here.
