The Marburg Colloquy

My (Confex's)  Systematic Theology Professor in seminary once remarked that  every Reformed believer should know what happened on October 1-4, 1529. This is when Marburg Colloquy took place? But what this colloquy all about?  How did it affect the later growth and spread of the Reformed faith? What are some of the good things we can learn from it and what are some things we should avoid in our own time? This and more in today's episode.
