Matthew 13 [:4–8] says that three sections of the field receive and contain the seed, but only the fourth section, the fine and good soil, bears fruit with patience. Now, wherever you hear or see this word preached, believed, professed, and lived, do not doubt that the true ecclesia sancta catholica, “a Christian holy people” must be there, even though their number is very small. For God’s word “shall not return empty,” Isaiah 55 [:11], but must have at least a fourth or a fraction of the field.
