Not exactly. He leaned Unitarian sometimes because he had doubts about the Trinity, supposedly. But he believed firmly in Jesus's miracles and the Resurrection--the very things Jefferson cut out of his Bible.
Thomas Jefferson was a confirmed skeptic, but I prefer to think of Charles Dickens as a sincere believer, albeit a latitudinarian ("big-tent") Anglican with some weak theological leanings. Nothing too unusual for the Victorian era.
Charles Spurgeon and Dickens were contemporaries, about 20 years apart in age. loved Dickens's novels and owned a complete set, though he was critical of Dickens's portrayal of religious figures in his stories (Dickens was a nominal Anglican but opposed to organized religion, and didn't like Nonconformists, of which the Baptist Spurgeon was one, or the evangelical "Low Church" wing of the C. of E.). But they had common ground in their concern for the poor and other social issues.
