What about Rom. 14:5? "One man esteems one day above another; another esteems every day alike. Let every man be fully persuaded in his own mind." Really, what difference does a day make?

Sometimes it's helpful to carefully notice what a Bible text does not say as well as what it does say. Verses 5 and 6 say nothing about either worship or the Sabbath. They simply talk about regarding a day.To say this particular day is the Sabbath is an unwarranted assumption. Rom. 14:1 sets the tone for the entire passage indicating that the discussion focuses on "doubtful disputations" or disputes on doubtful matters.

Is the seventh-day Sabbath set apart by God at creation (Gen. 2:1-3) placed within the heart of the moral law (Ex. 20:8-11) a doubtful matter? Certainly not!The key to our passage is found in verse 6 which states, "He that regards the day regards it unto the Lord, and he that regardeth not the day regards it not to the Lord. He that eateth, eateth to the Lord for He giveth God thanks, and he that eateth not to the Lord, he eateth not for he giveth God thanks."

The issue revolved around fast days not Sabbath days. Some Jewish Christians believed there was particular merit in fasting on certain days. They judged others by their own standards. The Pharisees fasted at least twice a week and boasted about it (Lk. 18:12). In Rom. 14, Paul is pointing out that to fast or not to fast on a certain day is a matter of individual conscience, not a matter of God's command.
