No, it isn't. It's a subject without an object.
It was, incidentally, that great man, Thomas Paine:
The study of theology, as it stands in Christian churches, is the study of nothing; it is founded on nothing; it rests on no principles; it proceeds by no authorities; it has no data; it can demonstrate nothing; and it admits of no conclusion. Not anything can be studied as a science, without our being in possession of the principles upon which it is founded; and as this is the case with Christian theology, it is therefore the study of nothing.
You think he was a great man, but plenty would disagree: "Thomas Paine had passed the legendary limit of life. One by one most of his old friends and acquaintances had deserted him. Maligned on every side, execrated, shunned and abhorred – his virtues denounced as vices – his services forgotten – his character blackened, he preserved the poise and balance of his soul. He was a victim of the people, but his convictions remained unshaken. He was still a soldier in the army of freedom, and still tried to enlighten and civilize those who were impatiently waiting for his death. Even those who loved their enemies hated him, their friend – the friend of the whole world – with all their hearts. On the 8th of June, 1809, death came – Death, almost his only friend. At his funeral no pomp, no pageantry, no civic procession, no military display. In a carriage, a woman and her son who had lived on the bounty of the dead – on horseback, a Quaker, the humanity of whose heart dominated the creed of his head – and, following on foot, two negroes filled with gratitude – constituted the funeral cortege of Thomas Paine."
Also, rather at variance with your quote, he also said, "I believe in one God, and no more; and I hope for happiness beyond this life."
