Title: Book of Revelation
Content:  Revelation is an apocalyptic prophecy with an epistolary introduction addressed to seven churches in the Roman province of Asia. "Apocalypse" means the revealing of divine mysteries; John is to write down what is revealed (what he sees in his vision) and send it to the seven churches. The entire book constitutes the letter—the letters to the seven individual churches are introductions to the rest of the book, which is addressed to all seven. While the dominant genre is apocalyptic, the author sees himself as a Christian prophet: Revelation uses the word in various forms twenty-one times, more than any other New Testament book.
Title: Seven churches of Asia
Content:  The letters follow a common pattern. For example: the Lord first addresses each church and identifies Himself, then defines things that He knows about the church in question. After this, a challenge or reproach is given, followed by a promise. In all seven cases the admonition is included, "He who has an ear, let him hear what the Spirit says to the churches", although sometimes this comes before the promise and sometimes after. Although the letters differ in length in accord with the needs of each community, all conclude with an appeal to hold fast and to listen to what the Spirit is saying to the churches. Each church is promised that everyone who conquers will be rewarded by Christ. Some historicists typically interpret the seven churches as representing seven different periods in the history of the Western 
Title: Revelation 14
Content:  Revelation 14 is the fourteenth chapter of the Book of Revelation or the Apocalypse of John in the New Testament of the Christian Bible.

The Three Angels' messages in verses 6 to 12 form a central feature of the teaching and mission of the Seventh-day Adventist Church: "“Make disciples of Jesus Christ who live as His loving witnesses and proclaim to all people the everlasting gospel of the Three Angels’ Messages in preparation for His soon return".

Title: Temple menorah
Content:  The New Testament Book of Revelation refers to a mystery of seven golden lampstands representing seven churches. The messages to the seven churches from Jesus Christ found have at least four applications: (1) a local application to the specific cities and believers in the church; (2) to all the churches of all generations; (3) a prophetic application unveiling seven distinct phases of church history from the days of the apostle John until today; (4) a personal application to individual believers who have ears to hear what the Spirit is saying. According to Clement of Alexandria and Philo Judaeus, the seven lamps of the golden menorah 
Title: The Word of the Lord
Content:  The Word of the Lord refers to one of two books of scripture used by certain factions of the Latter Day Saint movement. The first book, simply entitled The Word of the Lord, is used by members of the Church of Christ (Fettingite), the Church of Christ at Halley's Bluff and the Church of Christ (Restored). The second, called The Word of the Lord Brought to Mankind by an Angel, is accepted only by the Church of Christ with the Elijah Message, and churches derived from it, such as the Church of Christ (Assured Way). Both books contain revelations allegedly given to former Church of Christ (Temple Lot) Apostle Otto Fetting by an angelic being who claimed to be John the Baptist. The latter title also contains revelations purportedly given to William A. Draves by this same being, after Fetting's death.
Title: Church of Jesus Christ (Zion's Branch)
Content:  In September 2007, elder Ron Perkins of the Zion's Branch church offered a revelation entitled "An Admonition to all Saints of the Restoration". Although Perkins does not claim to be a prophet, he did assert that he had received this message "by the power of [the] Holy Spirit". In this short "admonition", Latter Day Saints in general are chided for following "sinful and ignorant men who have followed their own ways instead of God's ways", and "dishonorable priesthood" holders. The revelation admonishes its readers that God will no longer tolerate their "willful ignorance" of his truth. This revelation has been reproduced on the church's website.
