They urged this stranger to stay with them while they rested. And so the three of them dined together. And the man took bread, blessed it, broke it, and gave it to them. Then, suddenly, they recognized who this man really was. They were in the presence of the Lord Himself.
Bread is broken so that it can be shared.
To break bread and to share it with someone else is to communicate, to share, what is good. And to eat the bread that is offered is to appropriate it, to make it part of oneself. The bread which the Lord desires to share with us is His Divine good. He wants to give us of Himself. He wants to flow into our hearts with love and charity, and He wants us to receive this love, freely and with delight.
