A frustrating feature of our culture is the ongoing "war" between meat eaters, vegans, and vegetarians. On the one hand, meat eaters don't want to be judged by vegetarians. And for good reason. It's not fun to have some loon screaming in your face every time you have a sandwich. But often, they take it the other way. When people find out I'm a vegetarian (disclaimer: when I took up Krav Maga, I began eating meat again), the first thing they do is shout "bacon!" in my face.
I'm not going to pretend I know Romans 14 by heart. I couldn't recite it in 3 different translations, I'd need it in front of me to tell you exactly what it says, but needless to say that as someone who has received a lot of criticism for my dietary habits, I can tell you the general theme. As can many Christian vegetarians. Meat eaters, not so much.
Now, I'm not trying to stereotype, I'm not saying vegetarians are somehow superior, I'm not even trying to fan the flames of war between the two groups. Quite the opposite, in fact. I want to establish peace where it should have always been. I want to show that dietary preferences are such trivial differences that the only time they should be brought up is in the very context I am bringing them up now: To show that they aren't worth bickering about. Vegetarians, I'm sorry, but meat isn't murder. It's a tragic post-fall effect that post-flood man was given permission to make use of. Meat eaters, if you want to show a judgemental vegetarian this passage, do that, but shouting "bacon!" in the face of a vegetarian is just not cool.
The dispute about dietary preferences leaves a poor taste in my mouth. Dairys no reason to argue about this, so lettuce unite and pray. Don't make me throw more puns at you... Take the point, have fellowship with each other, know that we all worship the same God, who loves us regardless of what we stuff in our pie holes.
