If it is found that more restrictions are going to be needed to keep the virus under control people immediately jump to pubs and other hospitality venues which are essential to keeping the economy functioning, employ literally millions of people (and support the jobs of millions more), and are beneficial to the mental health of many of their clientele. Places of worship however provide no economic benefit, and are just as much of a vector of spread as people socialise with many others who they wouldn't otherwise see. This means that it would clearly make sense from an economic and societal stand point to close places of worships if this would allow pubs to stay open.
