St. Paul Center For Biblical Theology: "We should put ourselves in the shoes of the disciples in today’s Gospel. Downcast and confused they’re making their way down the road, unable to understand all the things that have occurred.
They know what they’ve seen - a prophet mighty in word and deed. They know what they were hoping for - that He would be the redeemer of Israel. But they don’t know what to make of His violent death at the hands of their rulers.
They can’t even recognize Jesus as He draws near to walk with them. He seems like just another foreigner visiting Jerusalem for the Passover.
Note that Jesus doesn’t disclose His identity until they they describe how they found His tomb empty but “Him they did not see.” That’s how it is with us, too. Unless He revealed himself we would see only an empty tomb and a meaningless death."
