Is Sunday the Christian Sabbath?

Is Sunday the Christian Sabbath? That’s in the Bible - NOT! 1 Corinthians 16:1-3 describes a fundraiser for Jerusalem, not necessarily a collection at Sunday services. Acts 20:7 is a special farewell service, not necessarily a regular Sunday service. Romans 14:5-13 gives permission to worship on any day we choose. Hebrews 4:9 says that there remains a Sabbath rest still to come, referring to our eternal rest. Colossians 2:16 suggests that we should not allow others to judge us by mandating certain days. There is always a tendency to criticize people for the days they prefer. Christians are free to keep any rest day they choose, following the spirit of the law: one day in seven.
