What was Mrs. Winthrop's main exhortation to Silas during this visit?

Mrs. Winthrop's main exhortation was an attempt to encourage Silas to attend church.

"Dear heart!" said Dolly, pausing before she spoke again. "But what a pity it is you should work of a Sunday, and not clean yourself—if you didn't go to church; for if you'd a roasting bit, it might be as you couldn't leave it, being a lone man. But there's the bakehus, if you could make up your mind to spend a twopence on the oven now and then,—not every week, in course—I shouldn't like to do that myself,—you might carry your bit o' dinner there, for it's nothing but right to have a bit o' summat hot of a Sunday, and not to make it as you can't know your dinner from Saturday. But now, upo' Christmas-day, this blessed Christmas as is ever coming, if you was to take your dinner to the bakehus, and go to church, and see the holly and the yew, and hear the anthim, and then take the sacramen', you'd be a deal the better, and you'd know which end you stood on, and you could put your trust i' Them as knows better nor we do, seein' you'd ha' done what it lies on us all to do."

Dolly's exhortation, which was an unusually long effort of speech for her, was uttered in the soothing persuasive tone with which she would have tried to prevail on a sick man to take his medicine, or a basin of gruel for which he had no appetite. Silas had never before been closely urged on the point of his absence from church, which had only been thought of as a part of his general queerness; and he was too direct and simple to evade Dolly's appeal.
