Interest or Boredom in the Sermon Scene of Tristram Shandy

Does the sermon scene in Tristram Shandy show the characters bored or interested?

"[Certainly, Trim, quoth my father, interrupting him, you give that sentence a very improper accent; for you curl up your nose, man, and read it with such a sneering tone, as if the Parson was going to abuse the Apostle" (Sterne 88). 

"The common talk of men must relate to facts in which the talkers have, or think they have, an interest; and where such facts cannot be known, the pleasures of society will be merely sensual" (Johnson, Idler No.7).

I'm unsure if the characters in the sermon scene are bored or interested in the sermon. Tristram's father interrupts Trim after only one sentence to interject his opinion on the sermon. Each character, in turn, does this throughout the whole scene. These seems to be evidence of the "common talk [...] which the talkers have [...] an interest." They interrupt frequently to argue the theology of the points being made or how the church carriers out its business. There are several instances of the characters hobby-horses coming out in their discussion. Toby and Trim compare certain passages to battles and battlements, Dr. Slop wakes up from his nap when physicians are mentioned, and Tristram's father continues his many peculiar opinions. In this quote the father is chastising Trim for reading the passage in a way he thinks improper.

The characters are talking about things they have interest in and knowledge of facts about them. This gives the appearance that they are interested in the sermon. However, the frequent interruptions could point to that they rather talk about what is on their minds than continue to hear the sermon. Their boredom in hearing the sermon could be satisfied by the "sensual" act of talking. Their talking could be purposed to have a more interesting conversation then what the sermon is presenting.
