Catena Aurea on Luke 24:25–35: Gregory the Great

Because then He was still a stranger to faith in their hearts, He feigned as if he would go further. By the word “fingere” we mean to put together or form, and hence formers or preparers of mud we call “figuli.” He who was the Truth itself did nothing then by deceit, but exhibited Himself in the body such as He came before them in their minds. But because they could not be strangers to charity, with whom charity was walking, they invite Him as if a stranger to partake of their hospitality. Hence it follows, And they compelled him. From which example it is gathered that strangers are not only to be invited to hospitality, but even to be taken by force.
