Luke 24:30 - Ellicott's Commentary On The Whole Bible

He took bread, and blessed it. — Had the two travellers been of the number of the Twelve, we might have thought of the words and acts as reminding them of their last Supper with their Lord. As it was, we must think of those words and acts as meant to teach them, and, through them, others, the same lesson that had then been taught to the Twelve, that it would be in the “breaking of bread” that they would hereafter come to recognise their Master’s presence. And they, too, we must remember, whether they were of the Seventy, or among the wider company of disciples, must have had memories, it may be of multitudes fed with the scanty provision of a few barley loaves, it may be of quiet evenings without a multitude, when they had looked on the same act, and heard the same words of blessing. This meal, too, became so full of spiritual significance that we may well anticipate the technical language of theology and say that it was to them “sacramental.”
