MATT. xxviii. 16-20.
This brief concluding passage is all St. Matthew gives us of the thirty-nine days which followed the Resurrection and preceded the Ascension. It would seem as if he fully realised that the manifestations of these days belonged rather to the heavenly than to the earthly work of Jesus, and that therefore, properly speaking, they did not fall within his province. It was necessary that he should bear witness to the fact of the Resurrection, and that he should clearly set forth the authority under which the first preachers of the gospel acted. Having accomplished both, he rests from his long labour of love.
That the commission of the eleven was not restricted to this particular time and place is evident from notices in the other Gospels (Mark xvi. 15; Luke xxiv. 48; John xx. 21-23, xxi. 15-17); but we can see many reasons why this occasion was preferred to all others. We have already seen how natural it was that St. Matthew should call the attention of his readers to the appearances of the risen Lord in Galilee rather than to those in Jerusalem and its vicinity; and the more we think of it, the more do we see the appropriateness of his singling out this one in particular. It was the only formally appointed meeting of the Lord with His disciples. In every other case He came unannounced and unexpected; but for this meeting there had been a distinct and definite appointment.
This consideration is one of many which render it probable that this was the occasion referred to by St. Paul when our Lord was seen by above five hundred brethren at once; for on the one hand there was nothing but a definite appointment that would bring so large a company together at any one point, and on the other hand, when such an appointment was made, it is altogether natural to suppose that the news of it would spread far and wide, and bring together, not the eleven only, but disciples from all parts of the land, and especially from Galilee, where the greater number of them would no doubt reside. That St. Matthew mentions only the eleven may be accounted for by the object he has in view--viz., to exhibit their apostolic credentials; but even in his brief narrative there is one statement which is most easily understood on the supposition that a considerable number were present. "Some doubted," he says. This would seem altogether natural on the part of those to whom this was the only appearance; whereas it is difficult to suppose that any of the eleven could doubt after what they had seen and heard at Jerusalem.
In any case, the doubts were only temporary, and were in all probability connected with the mode of His manifestation. As on other occasions, of which particulars are given in other Gospels, the Lord would suddenly appear to the assembled company; and we can well understand how, when first His form was seen, He should not be recognised by all; so that, while all would be solemnised, and bow in adoration, some might not be altogether free from doubt. But the doubts would disappear as soon as "He opened His mouth and taught them," as of old. To make these doubts, as some do, a reason for discrediting the testimony of all is surely the very height of perversity. All the disciples were doubters at the first. But they were all convinced in the end. And the very fact that it was so hard to convince them, when they were first confronted with so unexpected an event as the Lord's appearing to them after His death, gives largely increased value to their unfaltering certainty ever afterwards, through all the persecution and sufferings, even unto death, to which their preaching the fact of the Resurrection exposed them.
As Galilee was the most convenient place[37] for a large public gathering of disciples, so a mountain was the most convenient spot, not only because of its seclusion, but because it would give the best opportunity for all to see and hear. What mountain it was we can only conjecture. Perhaps it was the mount on which the great Sermon was delivered which gave the first outline sketch of the kingdom now to be formally established; perhaps it was the mount which had already been honoured as the scene of the Transfiguration; but wherever it was, the associations with the former mountain scenes in Galilee would be fresh and strong in the disciples' minds.
