John Chrysostom
Catena Aurea · Markusevangelium 4
And he said, Whereunto shall we liken the kingdom of God? or with what comparison shall we compare it? It is like a grain of mustard seed, which, when it is sown in the earth, is less than all the seeds that be in the earth: But when it is sown, it groweth up, and becometh greater than all herbs, and shooteth out great branches; so that the fowls of the air may lodge under the shadow of it. And with many such parables spake he the word unto them, as they were able to hear it. But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples.
(non occ. leg. ap. Possin. Cyril.) And also because the wisdom spoken amongst the perfect expands, to an extent greater than all other sayings, that which was told to men in short discourses, for there is nothing greater than this truth.
