This episode will focuses on the Fourth Lateran Council, a 13th century event you have likely never heard of – and can’t imagine you are listening to a lecture on it. But this council – which is often referred to as the Great Council – is important for a handful of reasons. The one Mike will be highlighting today deals with the formalized endorsement of the doctrine of Transubstantiation. Which is the Roman Catholic idea that the communion elements become the actual body and blood of Christ during the prayer of consecration by a priest.
