Theophylact of Ohrid
Catena Aurea · Lukasevangelium 24
And as they thus spake, Jesus himself stood in the midst of them, and saith unto them, Peace be unto you. But they were terrified and affrighted, and supposed they had seen a spirit. And he said unto them, Why are ye troubled? and why do thoughts arise in your hearts? Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have. And when he had thus spoken, he shewed them his hands and feet. But let us see what mystery it was for the sake of which, according to Matthew and Mark, our Lord when He rose again gave the following command, I will go before you into Galilee, there shall ye see me. Which although it was accomplished, yet it was not till after many other things had happened, whereas it was so commanded, that it might be expected that it would have taken place alone, or at least before other things.
The Lord then standing in the midst of the disciples, first with His accustomed salutation of “peace,” allays their restlessness, shewing that He is the same Master who delighted in the word wherewith He also fortified them, when He sent them to preach. Hence it follows, And he said to them, Peace be unto you; I am he, fear not.
