The answer
What makes you conclude that it is our Lord Jesus Christ who speaks in the Holy Book of Revelation 1:17,18 and not in the Holy Book of Revelation 1:8. The writer of this book, St. John said that he had heard behind him a loud voice saying "I am the Alpha and the Omega, the Beginning and the End," says the Lord, "who is and who was and who is to come, the Almighty" (Rev 1:8), and when he turned to see the voice that spoke he saw One like the Son of Man (Rev 1:13) and that same One laid His right hand on him saying "Do not be afraid; I am the First and the Last. I am He who lives, and was dead, and behold; I am alive forevermore. Amen. And I have the keys of Hades and of Death" (Rev 1:18-19). So, how can you say that it is God the Father who was speaking in Verses 18-19; when it is clearly mentioned that it was the Son of Man, the same who was speaking in the Holy Book of Revelation 1:8 our Lord Jesus Christ, "the Alpha and the Omega, the Beginning and the End”; which is a clear statement that He was the Alpha, the Beginning before all ages.Answered by His Eminence Metropolitan Youssef (opens in a new tab)
