Is Sunday the Lords Day?
The Bible uses the phrase the “Lord’s day” only once in Revelation 1:10, so we know the Lord does have a special day. But there is not one single verse in the whole Bible that refers to Sunday as the “Lord’s Day.” However, the Bible does plainly identify the Sabbath as the Lord’s Day. The only day ever blessed by the Lord or claimed by Him as His holy day is the Seventh day Sabbath.
