She had taken her Bible to look out the reference and found it to be:—

Having many tilings to write unto you, I would not write
with paper and ink: but I trust to come unto you, and speak
face to face, that our joy may be full.

The envelope was postmarked New York, and she smiled, thinking that Mrs. Emerson, a charming lady who had spent the summer in Edgewood, and had sung with her in the village choir, was coming back, as she had promised, to have a sleigh ride and see Edgewood in its winter dress. Nancy had almost forgotten the first letter in the excitements of her busy day, and now here was another, from Boston this time. She opened the envelope and found again only a simple sentence, printed, not written. (Lest she should guess the hand, she wondered?)

Second Epistle of John. Verse 5.—
And now I beseech thee, lady, not as though I wrote a new commandment
unto thee, but that which we had from the beginning, that we love one
another.

Was it Mrs. Emerson? Could it be—any one else? Was it? No, it might have been, years ago; but not now; not now!—And yet; he was always so different from other people; and once, in church, he had handed her the hymn-book with his finger pointing to a certain verse.

She always fancied that her secret fidelity of heart rose from the fact that Justin Peabody was “different.” From the hour of their first acquaintance, she was ever comparing him with his companions, and always to his advantage. So long as a woman finds all men very much alike (as Lobelia Brewster did, save that she allowed some to be worse!), she is in no danger. But the moment in which she perceives and discriminates subtle differences, marveling that there can be two opinions about a man's superiority, that moment the miracle has happened.

And now I beseech thee, lady, not as though I wrote a new commandment
unto thee, but that which we had from the beginning, that we love one
another.

No, it could not be from Justin. She drank her tea, played with her beans abstractedly, and nibbled her slice of steaming brown bread.

Not as though I wrote a new commandment unto thee.

No, not a new one; twelve, fifteen years old, that commandment!
