"How many hundreds of years needs it to make a steward a king, if the king returns not? " he asked. "Few years, maybe, in other places of less royalty," my father answered. "In Gondor ten thousand years would not suffice." Alas! poor Boromir. Does that not tell you something of him? '
'It does,' said Frodo. `Yet always he treated Aragorn with honour.'
'I doubt it not,' said Faramir. `If he were satisfied of Aragorn's claim as you say, he would greatly reverence him. But the pinch has not yet come. They had not yet reached Minas Tirith or become rivals in her wars

A valuable quote when considering Denethor in relation to Aragorn. I leave it up to you to interpret it.
