The B-Side Bible: Your backstage pass to what didn't make the sermon.

The B-Side Bible: Your backstage pass to what didn't make the sermon.

"They Didn't Teach That At School" has been renamed The B-Side Bible. The B-Side Bible is a playful nod to the forgotten, overlooked, and underappreciated parts of Christianity and the Bible — much like a B-side on an old vinyl record. While the A-sides are the polished, well-known stories you hear in sermons (think Noah, Moses, and Jesus’ greatest hits), the B-sides are the strange visions, fringe characters, obscure rules, and wild moments hiding in the background. This podcast is your backstage pass to what didn’t make the sermon — the sacred oddities, quirky tales, and theological curveballs that rarely get the spotlight but are just as fascinating. Mark Kerrigan is a teacher with a bachelor of Education and a Master’s degree in Theological Studies. Mark has been teaching for twenty years and has also written 2 novels.

Long before Christianity settled into creeds and councils, it was a field of competing ideas — and some of the most striking came from the movement we now call Gnosticism.

For nearly two thousand years, Judas Iscariot has stood as Christianity’s ultimate betrayer. But one ancient text — discovered in Egypt and finally brought to light in the early 21st century — tells a different story.

In this episode, we explore The Gospel of Judas, an early Gnostic text that repositions Judas not as the villain, but as the one disciple who understood Jesus’ true mission. We examine where this gospel...

If there’s a celebrity among numbers, it’s 666. It shows up where you least expect it: on horror posters, in guitar solos, on stolen highway signs, on novelty merchandise, and even in cheeky bus timetables. Whole marketing campaigns have timed releases to it, bands have built careers around it, and newsrooms can’t resist a headline that sneaks it in. For some, 666 is spooky; for others, it’s a wink and a nudge—an in...

Mark’s Gospel is short, raw, and famously ends in silence — no nativity, no resurrection appearances, no triumphant conclusion. So how did this rough first draft of the Jesus story survive when flashier Gospels came along? In this episode, we explore the surprising reasons Mark’s Gospel made the final cut. From apostolic name-dropping and Gentile appeal to performance-ready storytelling and possible Homeric influenc...
