A world adventurer, an opinionated engineer, and a very well read missionary priest walked into a sound studio... welcome to Sons of Thunder! From 2006 to 2008 Sam Clear walked 15,600km around the world for the complete unity of the church in truth and in love. He nearly died 11 times. Marty, his best mate, freely offered his opinion in the planing stages, during the journey, and pretty much every day since. And Fr Dave Callaghan, before, during and after the journey, offered far more sound advice. Now the three friends unpack the complexities of faith through the lens of the walk for unity, beginning with their own adventures together, and the confronting reality of disunity.
