In this episode, Jonathan and Fr Justinian begin by going through some material of The Longer Catechism by St Philaret of Moscow, carefully examining the difference between Faith and lower, rational knowledge. This leads to a discussion of the nature of the 'unbelief' of St Thomas, which provides a springboard for discussing the initiatory nature of Orthodoxy, and the fact that certain knowledge comes to us only when we conform our will to the will of God.
