How did they come to hold together? How had they not yielded to the temptation to seek safety by flight, which would have been the natural course after the death of their Leader on a charge of treason against the Roman power? The process of disintegration had begun, and we see it going on in the conduct of the disciples before the Resurrection. The Shepherd was smitten,' and, as a matter of course, the sheep' began to scatter.' And yet here we find them back in Galilee, in their old haunts, and not trying to escape by separation, which would have been the first step suggested to ordinary men in an ordinary state of things. But where everybody knew them, and they knew everybody, and everybody knew them to be disciples of Jesus Christ, thither they go, and hold together as if they had still a living centre and a uniting bond. How did that come about? The fact that after Christ's death there was a group of men united together simply and solely as disciples, and exhibiting their unity as disciples conspicuously, in the face of the men that knew them best, this forms a strange phenomenon that needs an explanation. And there is only one explanation of it, that Jesus Christ had risen from the dead. That drew them together once more. You cannot build a Church on a dead Christ; and of all the proofs of the Resurrection, I take it that there is none that it is harder for an unbeliever to account for, in harmony with his hypothesis, than the simple fact that Christ's disciples held together after He was dead, and presented a united front to the world.
So, then, the fact of the group is itself significant, and we may claim it as being a morsel of evidence for the historical veracity of the resurrection of Jesus Christ.
