The 3 Most Misunderstood Verses in Scripture
The three most mistranslated scriptures in the Bible have to be Romans 14:5-6, Galatians 4:8-10, and Colossians 2:16-17. In order to understand the truth of the following three statements, we need is to understand the context of the passages!
The context of this passage is that Paul is concerned about brethren who are "weak in their faith." having "doubtful debates or arguments". What were those doubtful things? The man made laws that had been set concerning eating traditions, such as washing hands before eating, or eating meat bought from the market because it may have been sacrificed to a pagan god. When speaking of days, it refers to the fact that both the Pharisees and Saduccees had come up with different rules concerning some holy day observances.
If you read the first verse it makes clear that the topic here is pagan worship. These were gentiles that had converted and were having a hard time letting go of their pagan observances at certain times of the year.
Foods, festivals, new moons, and sabbaths ARE the substance of Christ. Christians should not worry about what others are saying in judging you on what you eat, or drink, or how you observe the festivals (holy days), or the Sabbath, but keep them as you have learned them because they will be kept in the future as well, just as Christ also kept them.
