This passage talks about one issue (passing judgment on one another) with Paul giving two examples of how the issue is being propagated. The two issues are Sabbath observance and the Jewish dietary law. What was Sunday like for you growing up? How has that day changed for you over the years?
Do you tend to view all matters as being disputable (lots of grey areas) or do you more naturally view no matter as being disputable (everything is black and white)?
This question takes some self awareness - Can you see any area in which you may be a weaker believer? Remember, weaker doesn’t mean immature.
If you consider yourself a “stronger believer” in a particular matter, what is your priority: enjoying your freedom or giving it up to serve another Christian?
What argument does Paul give for them to accept one another in verse 1-3? What about in verse 4?
How does the truth that we will all stand before God’s judgement affect you?
