What does it mean to keep the Sabbath as a Christian?
We should allow Scripture to answer that. Let’s read what the apostle Paul declares in Colossians 2:16-17. “Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: Which are a shadow of things to come; but the body is of Christ.”
“One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.”Romans 14:5
These Scriptures make it clear that, for the Christian, Sabbath-keeping is a matter of spiritual freedom, not a command from God. It is a matter which each Christian needs to fully be convinced in his/her own mind.
Sabbath-keeping was not one of the commands the apostles felt was necessary to force on Gentile believers.
Latter-day Saints believe the Sabbath is a day of worship.
