I'm putting this in the Fundamental Baptist Forum because it references an article by Fundamentalist Kevin Bauder, Food Pharisees.
People who are willing to extend Christian fellowship to apostates, people who reject biblical teachings about sexuality, and people who want to get more Christians to drink booze all try to gain credibility by pontificating against gluttony. It’s the popular sin to oppose. Gluttony has no defenders.
Considering the rotundity of some of the preachers I remember railing against raising a glass, perhaps preaching on alcohol helped distract them from the topic of their own addictive sin. There’s nothing like diverting attention from your sin by bellowing about someone else’s. For some of the guys I’ve seen in pulpits, “pass the plate” has meaning beyond just tithes and offerings.
This is not to suggest that we should hear more preaching against gluttony. There is actually good reason to preach about other sins before we start harping about this one.
