This passage reminded me of an experience.
A few years ago, one of the elders in our KH gave a Sunday talk and in it he was discussing how in the churches Christmas and Easter are held as the most important days of the year. He said, 'in contrast, "we" (meaning JWs) hold Nisan 14 as the most important day of the year.' Of course, his point was that JWs have it right.
After the talk, I approached him and brought up that part of the talk and told him that he only presented two sides of the argument. That there was a third viewpoint he did not mention. When he looked at me wondering what I was referring to, I told him he would find the third view in Romans 14:5 (which is part of the same context with Rom 14:1).
I never got a reply from him, but several other standing around promptly opened their Bibles to see what I was referring to. None of them ever said anything to me about it afterward either.
