Charles Ellicott Commentary Luke 24:35

"And they rehearsed the things [that happened] in the way, and how he was known of them in the breaking of the bread." — Luke 24:35 (ASV)

He was known of them in breaking of bread.—The use by St. Luke of a term which, when he wrote, had already acquired a definite secondary meaning, as applied to “breaking bread” in the Supper of the Lord (Acts 2:42; Acts 2:46; 1 Corinthians 10:16), is every way significant. He meant people to connect the recognition at Emmaus with their daily or weekly communion in the Body and Blood of Christ.
