Mark 16:13 Commentary - Whedon's Commentary on the Old and New Testaments

13. They The two disciples from Emmaus. The residue The rest of their fellow apostles. Neither believed they them There was perhaps a reasonableness in this distrust of particular relations of our Lord’s appearances. A due skepticism of any particular story was doubtless right.

It did not imply necessarily a disbelief that the Lord would rise again according to his promises. In fact, like true philosophers, the disciples held that no narrative of the kind should be accepted until it had been fully tested by the most satisfactory evidence. Hence their skepticism affords just ground for our belief. Their testimony is the testimony of incredulous and scrutinizing witnesses.
