What are those discourses which you hold with each other? What was at that time, as we perceive, done openly by Christ, we daily feel to be accomplished in ourselves in a secret manner; which is, that of his own accord he approaches us unperceived for the purpose of instructing us. Now from the reply of Cleopas it is still more evident that, as I have lately mentioned, though they were in doubt and uncertainty about the resurrection of Christ, yet they had in their hearts a reverence for his doctrine, so that they were far from having any inclination to revolt. For they do not expect that Christ will anticipate them by making himself known, or that this fellow-traveler, whoever he may be, will speak of him respectfully; but, on the contrary, having but a small and obscure light, Cleopas throws out a few sparks on an unknown man, which were intended to enlighten his mind, if he were ignorant and uninformed. The name of Christ was, at that time, so generally held in hatred and detestation, that it was not safe to speak of him respectfully; but spurning from him suspicion, he calls Christ a prophet of God, and declares that he is one of his disciples. And though this designation falls greatly below the Divine Majesty of Christ, yet the commendation which he bestows, though moderate, is laudable; for Cleopas had no other intention than to procure for Christ disciples who would submit to his Gospel. It is uncertain, however, if it was through ignorance that Cleopas spoke of Christ in terms less magnificent than the case required, or if he intended to begin with first principles, which were better known, and to rise higher by degrees. Certain it is, that a little afterwards, he does not simply place Christ in the ordinary rank of prophets, but says that he and others believed him to be the redeemer.

What manner of communications - What is the subject of your conversation? What is it that has so much affected your minds? They were deeply affected in the recollection of the death of Jesus; and, as became all Christians, they were conversing about him, and were sad at the overwhelming events that had come upon them.

And he said unto them,.... That is, "Jesus", as the Persic version, or "our Lord", as the Ethiopic version, expresses it:
what manner of communications are these, that ye have one to another, as ye walk? what is the subject of your discourse; what is it your conversation one with another turns upon in your journey?
and are sad? what melancholy story are you telling to one another, which causes such sadness of countenance, and dejection of mind? for Christ by their countenances and gestures, as the shaking of their heads, and lifting up and wringing of their hands, could easily discern as man, as well as know as God, that they were full of sorrow and heaviness, and which were occasioned and increased by what they were talking of.

communications, &c.--The words imply the earnest discussion that had appeared in their manner.
