That's not quite right. It is causing a brother to offend, that is, to be tempted to do wrong. Since drinking alcohol is not wrong, according to the Bible, and Paul himself suggested Christians should do their drinking at home, it is drinking wine or eating meat that has some religious significance, like being sacrificed to idols, and which might cause someone used to using those things in pagan rituals to be spiritually weakened.
Do you really think that's a problem today?

But take heed lest by any means this libery of yours become a stumblingblock to them that are weak (1Cor.8:9)
I am not saying that 'Faith' is the 'weak' brother in the issue, but I am saying that if an issue comes up between two brothers, the one is doing the offending should bend over backwards not to.
Even so, come Lord Jesus
