With what spirit might not Lucian have painted two priests

From Charles Lamb’s Grace Before Meat:

I once drank tea in company with two Methodist divines of different persuasions, whom it was my fortune to introduce to each other for the first time that evening. Before the first cup was handed round, one of these reverend gentlemen put it to the other, with all due solemnity, whether he chose to say anything. It seems it is the custom with some sectaries to put up a short prayer before this meal also. His reverend brother did not at first quite apprehend him, but upon an explanation, with little less importance he made answer that it was not a custom known in his church: in which courteous evasion the other acquiescing for good manners’ sake, or in compliance with a weak brother, the supplementary or tea-grace was waived altogether. With what spirit might not Lucian have painted two priests, of his religion, playing into each other’s hands the compliment of performing or omitting a sacrifice, – the hungry God meantime, doubtful of his incense, with expectant nostrils hovering over the two flamens, and (as between two stools) going away in the end without his supper.
