In the context of the “Legend of the Seven Churches,” it is important to note that this term is not commonly recognized as a specific historical or religious concept. However, there is a biblical reference to the “Seven Churches of Revelation,” also known as the “Seven Churches of Asia” or the “Seven Churches of the Apocalypse.” These seven churches are mentioned in the Book of Revelation, also known as the Apocalypse of John, which is the last book of the New Testament in the Christian Bible.

According to the biblical account in Revelation, the first revelation was received by the Apostle John, who was exiled to the island of Patmos for his faith. While on Patmos, John received a series of visions and revelations from Jesus Christ, which he recorded in the Book of Revelation.

In Revelation 1:11, John writes that he was instructed by Jesus to write down what he saw in a book and send it to the seven churches: Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia, and Laodicea. Each of these churches was located in the province of Asia (present-day western Turkey) at the time.

Therefore, the first revelation in the context of the Seven Churches of Revelation was given to the Apostle John, who later shared the visions and messages with these specific seven churches.
