The Carol was first published in a time of great religious controversy, and its absence of babes, wisemen,
stars, mangers and other icons* of the Chritsian Nativity inspired a multitude of sermons and pamphlets. Some religious leaders believed that any story fo Christmas without references to the birth of Jesus was self-indulgent and un-christian, and that the ritualistic celebrations in the story were pagan and sinful.
Although A Christmas Carol is generally associated with the Christian holiday season, for it does contain references to the Christian Jesus, its themes are not exclusive to Christianity and it inspired a tradition for decades in Christmas books and celebrations that appealed to many non-christians.
In other words, the traditional, seemingly meaningful (non-commercial) christmas of Dickens (published in magazines because Dickens was broke) was thought to be crass and heretical. This story was part of a general campaign to bring back Ye Olde Christmas which went out of favour in England after the Cromwellian Recolt in the mid 17th-century abolished it.
* The manger, wisemen, star, Frankincense and myrrh were elements of the birth of Mithra, a much older god than Jesus.
