In Revelation 1:10 we read: - "On the Lord's Day I was in the Spirit..."
Many people read into that verse that John was stating something that occurred on a Sunday, because in their mind's, the "Lord's Day" is Sunday. We are convinced that is not the case. The "Day of the Lord" is a phrase found numerous times in the Bible. That phrase is associated with the day of judgment! "The Lord's Day" is another way of saying "the day of the Lord". Consider the context of the verse in Revelation 1:10! The book of Revelation is about the revealing of Jesus Christ IN JUDGMENT. It begins in chapters 2 & 3 with judgment of the churches (judgment must begin at the house of God - Ezekiel 9:6; 1 Peter 4:17). What follows is chapter after chapter of judgment! The "Lord's Day" is the "Day of the Lord" which is the day of God's judgment of men - not a nice sweet time of Christian "fellowship" on the first day of the week!
We have not found many who concur with this position. Recently we found a post by the Israel Study Center which DOES agree with our position. We quote: "In one of the visions characteristic of Jewish apocalyptic tradition, John finds himself “in the spirit on the Lord’s Day” (Rev. 1:10). In view of modern controversies many Christ-followers wonder whether it was the seventh or the first day of the Israelite week that John had in mind. Both options, Sunday (1st day) and the Sabbath Day (7th day), while possible are a bit problematic for several reasons. One of them is that while the Sabbath Day does belong to the Lord it was never called the “Lord’s Day” before. On the other hand, Sunday, the Day that the resurrection of Jesus had become public, was never referred to as the “Lord’s Day” either. It could be argued, however, that “There is first time for everything”, but I would like to submit to you another possibility that should be also considered. “The Lord’s Day” is none other than “The Day of the Lord” spoken of so often by the prophets of Israel (Is. 2:12-22). According to Isaiah this is the day when justice finally prevails as the God of Israel judges his enemies and rewards his children with peace and prosperity. So, was this Saturday or Sunday? Neither. It was the Day of the Lord."
