It's MArley, not MErley- he is Ebenezer Scrooge's deceased buisness partner, who appears to Scrooge as a ghost on Christmas Eve weighed down with chains, ledger books and strongboxes.
In personality he was Scrooge's junior partner in the law firm they ran together, and was treated badly by Ebenezer, eventually dying of an illness due to being overworked and not being paid enough money to pay for medical care. He returns to warn Scrooge of the impending visit of the three Spirits, to warn him to take heed of their messages, and to berate him for his ill-treatment of Marley in life. he is, in essence, an embodiment of the effect that Scrooge has upon people, and this is symbolised by the chains he is bound in, plus the ledgers and safes that Scrooge kept him metaphorically 'bound' to in life.
The story A Christmas Carol begins on Christmas Eve.
Dickens would not have had a purpose to create a ghost that did not speak in a Christmas carol. His story was based on the ghost of Christmas past, and therefore needed to speak in Christmas carols and hymns.
