'My son,' said Gilraen, 'your aim is high, even for the descendant of many kings. For this lady is the noblest and fairest that now walks the earth. And it is not fit that mortal should wed with the Elf-kin.'
'Yet we have some part in that kinship," said Aragorn, "if the tale of my forefathers is true that I have learned.'
'It is true," said Gilraen, 'but that was long ago and in another age of this world, before our race was diminished. Therefore I am afraid; for without the good will of Master Elrond the Heirs of Isildur will soon come to an end. But I do not think that you will have the good will of Elrond in this matter.'
'Then bitter will my days be, and I will walk in the wild alone,' said Aragorn.
‘That will indeed be your fate,' said Gilraen; but though she had in a measure the foresight of her people, she said no more to him of her foreboding, nor did she speak to any one of what her son had told her.
But Elrond saw many things and read many hearts. One day, therefore, before the fall of the year he called Aragorn to his chamber, and he said: 'Aragorn, Arathorn's son, Lord of the Dúnedain, listen to me! A great doom awaits you, either to rise above the height of all your fathers since the days of Elendil, or to fall into darkness with all that is left of your kin. Many years of trial lie before you. You shall neither have wife, nor bind any woman to you in troth, until your time comes and you are found worthy of it.'
Then Aragorn was troubled, and he said: 'Can it be that my mother has spoken of this?'
‘No indeed,' said Elrond. 'Your own eyes have betrayed you. But I do not speak of my daughter alone. You shall be betrothed to no man's child as yet. But as for Arwen the Fair, Lady of Imladris and of Lórien, Evenstar of her people, she is of lineage greater than yours, and she has lived in the world already so long that to her you are but as a yearling shoot beside a young birch of many summers. She is too far above you. And so, I think, it may well seem to her. But even if it were not so, and her heart turned towards you, I should still be grieved because of the doom that is laid on us.'
[...]
When Elrond learned the choice of his daughter, he was silent, though his heart was grieved and found the doom long feared none the easier to endure. But when Aragorn came again to Rivendell he called him to him, and he said:
'My son, years come when hope will fade, and beyond them little is clear to the. And now a shadow lies between us. Maybe, it has been appointed so, that by my loss the kingship of Men may be restored. Therefore, though I love you, I say to you: Arwen Undómiel shall not diminish her life's grace lot less cause. She shall not be the bride of any Man less than the King of both Gondor and Arnor. To the men even our victory can bring only sorrow and parting – but to you hope of joy for a while. For a while. Alas, my son! I fear that to Arwen the Doom of Men may seem hard at the ending.'

Ca paraît effectivement clair dans un premier temps qu'Arwem est nettement au-dessus d'Aragorn, mais ce qu'Elrond finit par dire, c'est qu'elle ne pourra épouser qu'un *homme* de rang équivalent au sien et il ne peut y en avoir 50 : le roi de Gondor et d'Arnor réunis. Autrement dit, Aragorn ne peut prétendre épouser Arwen sur la seule base de son hérédité sanguine, il lui faut aussi reconquérir ce que ses aïeux ont perdu: l'hérédité dynastique. Au final, il est donc sur un pied d'égalité avec Arwen.
