Alpha and Omega Ministries was involved in two separate debates this past week, both of which you can listen to for free.
The first was on the topic of Calvinism. James White appeared on Dr. Michael Brown's show Line of Fire to discuss this issue. You can listen or download this debate here.
The second was on the topic of 1 Corinthians 3 and the doctrine of purgatory. Tim Staples of Catholic Answers appeared on James White's show The Dividing Line. You can listen or download this debate here.
