What do the Seven Seraphs stand for?

Hello humble combatants. I have had an epiphany about our faction. The Seraphim are of religious nature. They are described in the Book of Isaiah, which is a book in the Bible. Here is a passage describing them. ~ ~ ~ ~ ~ ~ ~ ~ Seraphim stood above Him, each having six wings: with two he covered his face, and with two he covered his feet, and with two he flew. 3 And one called out to another and said, “Holy, Holy, Holy, is the Lord of hosts, The [a]whole earth is full of His glory.” 4 And the [b]foundations of the thresholds trembled at the voice of him who called out, while the [c]temple was filling with smoke. 5 Then I said, “Woe is me, for I am ruined! Because I am a man of unclean lips, And I live among a people of unclean lips; For my eyes have seen the King, the Lord of hosts.” 6 Then one of the seraphim flew to me with a burning coal in his hand, which he had taken from the altar with tongs. 7 He touched my mouth with it and said, “Behold, this has touched your lips; and your iniquity is taken away and your sin is [d]forgiven.” ~ ~ ~ ~ ~ ~ Seraphim are seen as servants of God in Christian doctrine. Specifically here, they bring God's forgiveness to the Prophet Isaiah. They are also known to eternally worship God. Because of the nature of the Seraph, I have made a pliable hypothesis regarding why our faction is named after them. The Seven Seraphs may be a faction that reveres the Traveler as a god. We have seven leaders, referred to as "Seraphs". These Seraphs lead their followers in worshiping the Traveler and create doctrine about it. Presumably, they assimilate others into the faction through evangelization and fight those who oppose them. Perhaps it is the opposite though. Maybe we despise the Traveler and believe the aliens are our gods. Maybe we are stubborn, violent, and ruthless, indoctrinating people and forcing to join us. What if we slaughter all those who refuse our belief? What do you think guys? Any input? From the [url=http://www.bungie.net/7_Seven-Seraphs/en-us/Groups/Detail?groupId=18197]Seven Seraphs[/url]
