I have been listening to this podcast since it started, and it has been well worth it. I had previously read all of the New Testament, but getting through the Old Testament is a large, time-consuming task. I wasn't sure how I'd really be able to start and see it through. So, when I heard about this podcast, I began listening right away (through the Hallow app).
I agree, listening helps retain the words of Scripture. I don't follow along with the Bible either; the length is perfect for a ride to and from work each day. Fr. Schmitz's commentaries are very basic, but they are orthodox, and he highlights the most important passages of the day's readings.
Since this podcast is based on the Ascension Press "Great Adventure Bible," the theme of the quick studies each day is how the day's reading relate to salvation history.
This is my first post on this forum, but I saw the topic and wanted to echo what you said about the podcast.
