Based on the above passage from Revelation 6:1-2 New American Standard Bible (NASB), a common translation into English, the rider of the White Horse (sometimes referred to as the White Rider) is generally referred to as “Conquest”. The name could also be construed as “Victory”, as in the translation found in the Jerusalem Bible (the Greek words are derived from the verb νικάω, to conquer or vanquish). He carries a bow, and wears a victor’s crown. The White Rider has also been called “Pestilence”, particularly in popular culture, but only over the last couple of centuries.
Irenaeus, an influential Christian theologian of the 2nd century, was among the first to interpret this Horseman as Christ himself, his white horse representing the successful spread of the gospel. Various scholars have since supported this notion, citing the later appearance, in Revelation 19, of Christ mounted on a white horse, appearing as The Word of God. Furthermore, earlier in the New Testament, the Book of Mark indicates that the advance of the gospel may indeed precede and foretell the apocalypse. The color white also tends to represent righteousness in the Bible, and Christ is in other instances portrayed as a conqueror.
However, opposing interpretations argue that the first of the Four Horsemen is probably not the horseman of Revelation 19. They are described in significantly different ways, and Christ’s role as the Lamb who opens the seven seals makes it unlikely that he would also be one of the forces released by the seals.
Besides Christ, the Horseman could represent the Holy Spirit. The Holy Spirit was understood to have come upon the Apostles at Pentecost after Jesus’ departure from Earth. The appearance of the Lion in Revelation 5 shows the triumphant arrival of Jesus in Heaven, and the first Horseman could represent the sending of the Holy Spirit by Jesus and the advance of the gospel of Jesus Christ.
Other interpretations relying on comparative religious research ascribe the first Horseman as guiding for “the right path”; Mahabharata Lord Krishna was a charioteer to Arjuna by riding on white horses, while Arjuna himself was an archer. (Source: Wikipedia)
