In apostolic days the disciples of Christ came together on the first day of the week, i.e., on the Lord's day, for the purpose of breaking bread, or celebrating the Lord's death.
If it be possible to show that the disciples were permitted to neglect this duty, or failed to enjoy this blessed privilege some one Lord's day, then, by the same course of reasoning, may it be established that we may set it aside one month, or six.
But it may be urged that in attending to this institution every Lord's day, it will become too common-will fail to be remembered by Christians. Indeed! By neglecting for one month, or two, or three, is there not still greater danger? Besides, would not the mind and heart lose, by neglect, the power of appreciation? Think on this. But allow an illustration that will show at once the folly of such would-be argument:
My dear mother -- my best earthly friend -- dies; leaves me her likeness, with her blessed name written below, with these words attached: "When you see this, remember your mother." But I look at it oftener than a friend thinks prudent. He admonishes: "Look into that face once in three months. By so doing your love for your mother will be intensified."' No, my friend, I am sure you are mistaken. Let me see that face that name every day; that will intensify my love for my dear mother, who has done so much for me. So Christians will grow stronger, day by day, in attending to the Lord's Supper as commanded. As filings of steel approach one common magnet, occupying a central place, and they, approaching the center, get nearer to each other, so with disciples in communing with the Lord. They get nearer to each other. Each one examines, or proves himself. I can not examine you, nor you me. This is the Lord's table, not yours, not mine.
