Afterward he appeared unto the eleven as they sat at table, and rebuked them for their unbelief and hardness of heart, because they believed not them who had seen him after he was risen.
All Commentaries on Mark 16:14 Go To Mark 16
Augustine of Hippo
AD 430
The Lord Jesus himself chided his disciples, his earliest followers who remained close to him, because they did not believe that he was now alive, but grieved over him as dead. They were the fathers of the faith, but they were not yet fully believers. They did not yet believe, although they were made teachers so that the whole world might believe what they were destined to preach and what they were going to die for. They did not yet believe that he, whom they had seen raising others from the dead, had himself arisen. Deservedly, then, were they rebuked.
