The Lord's Day
Revelation 1:10 is the
only verse in the Bible that has the phrase "Lord's day" (KJV).
Revelation 1:10-11 I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet, saying, I am Alpha and Omega, the first and the last.
Who is the Alpha and Omega? Who is the Lord?
Revelation 1:1-2 The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John: Who bare record of the word of God, and of the testimony of Jesus Christ, and of all things that he saw.
Revelation 1:8 I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
Revelation 22:16 I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
What day does the Lord Himself claim as His day?
Matthew 12:8 For the Son of man is Lord even of the sabbath day.
Mark 2:28
Therefore the Son of man is Lord also of the sabbath.
Luke 6:5 And he said unto them, That the Son of man is Lord also of the sabbath.
The seventh day Sabbath is the Lord's day, not Sunday.
