Luke 24:31

31. And their eyes were opened Utterly shallow and rationalistic is the interpretation of Alford, making these disciples discover Jesus by his mode of breaking bread! If neither voice, nor form, nor person, revealed the Lord, how absurd to suppose that his manner of breaking bread should accomplish the discovery. These two were not apostles, nor is it probable they were specially familiar with his style of breaking bread.

And they knew him There he stood, this very Messiah, of whom all Scripture was the harbinger; the sufferer, the heir of glory, the judge of the earth. Before this moment he could not reveal himself without disturbing their minds so as to unfit their understanding of the Scripture. And now he could reveal himself, to show that his exposition was authoritative and divine, being his own.

He vanished This finished the demonstration. He did not merely step out of the door. As they were beholding him, the place he occupied became at once vacant space. Then they knew that it was their Lord, and that their Lord was truly divine. Not Mary Magdalene, nor Peter, nor John, nor the whole college of apostles had as yet received such a favour as this vouchsafed to these two disciples, the one to us unnamed, and the other but a name!
