In the LDS Church archives there is a document by Joseph's mother Lucy Smith entitled the "Preliminary Draft" in which she speaks of her father-in-law giving Joseph Smith Sr. a copy of Age of Reason and "bade him read that until he believed it." Clearly Joseph Smith had access to the book even if he didn't read and study the entire thing.
The following comparison isn't an exhaustive list of similarities between Paine's words and Joseph's scriptures. It isn't intended to persuade anyone into thinking that the Age of Reason was a major source for the things Joseph Smith did (although some have speculated that Joseph Smith wrote what he did in response to the skepticism of the day). Clearly, the King James Version of the Bible was the largest source for the subsequent LDS scriptures. Compared to Age of Reason, there are several other sources which may have played a much larger roll in the developments (such as View of the Hebrews). It is even possible (although unlikely in my opinion) that Joseph Smith never even read View of the Hebrews or Age of Reason. Rather, he may have just been a product of the environment of the time which was heavily influenced by such works. In any event, here are some interesting possible responses which Joseph Smith may have made after reading Paine.
|Every national church or religion has established itself by pretending some special mission from God, communicated to certain individuals... No one will deny or dispute the power of the Almighty to make such a communication, if He pleases. But admitting, for the sake of a case, that something has been revealed to a certain person, and not revealed to any other person, it is revelation to that person only... and hearsay to every other, and consequently they are not obliged to believe it. It is a contradiction in terms and ideas, to call anything a revelation that comes to us at second-hand, either verbally or in writing... When Moses told the children of Israel that he received the two tables of the commandments from the hands of God, they were not obliged to believe him, because they had no other
authority for it than his telling them so; and I have no other authority for it than some historian telling me so... When I am told that the Koran was written in heaven and brought to Mahomet by an angel, the account comes too near the same kind of hearsay evidence and second-hand authority as the former. I did not see the angel myself and, therefore, I have a right not to believe it.

|And the day cometh that the words of the book which were sealed shall be read upon the house tops; and they shall be read by the power of Christ... Wherefore, at that day when the book shall be delivered unto the man of whom I have spoken,...three witnesses shall behold it, by the power of God, besides him to whom the book shall be delivered; and they shall testify to the truth of the book and the things therein.
-- 2 Nephi 27:11,12
And unto three shall (the plates) be shown by the power of God; wherefore they shall know of a surety that these things are
true. And in the mouth of three witnesses shall these things be
The Book of Mormon is accompanied by the testimony of three witnesses: Oliver Cowdery, David Whitmer, and Martin Harris, and by a further testimony by eight witnesses.
|As to the account of the creation, with which the book of
Genesis opens, it has all the appearance of being a tradition...
It begins abruptly. It is nobody that speaks. It is nobody that
hears. It is addressed to nobody. It has neither first, second,
nor third person. It has every criterion of being a tradition. It
has no voucher. Moses does not take it upon himself by introducing
it with the formality that he uses on other occasions, such as
that of saying, "The Lord spake unto Moses, saying."
-- p. 17
|And it came to pass that the Lord spake unto Moses, saying:
Behold, I reveal unto you concerning this heaven, and this earth;
write the words which I speak. I am the Beginning and the End, the
Almighty God; by mine Only Begotten I created these things; yea,
in the beginning I created the heaven, and the earth upon which
thou standest. And the earth was without form, and void; and I
caused darkness to come up upon the face of the deep; and my
Spirit moved upon the face of the water; for I am God. And I, God,
said: Let there be light; and there was light... (And so on with
"I, God" for the rest of Genesis l.)
-- Moses 2
|Though it is not a direct article of the Christian system
that this world that we inhabit is the whole of the habitable
creation, yet it is so worked up therewith, from what is called
the Mosaic account of the Creation... that to believe otherwise,
that is, to believe that God created a plurality of worlds, at
least as numerous as what we call stars, renders the Christian
system of faith at once little and ridiculous, and scatters it in
the mind like feathers in the air... Our ideas, not only of the
almightiness of the Creator, but of his wisdom and his
beneficence, become enlarged in proportion as we contemplate the
extent and the structure of the universe... From whence, then,
could arise the solitary and strange conceit that the Almighty,
who had millions of worlds equally dependent on his protection,
should quit the care of all the rest and come to die in our world,
because, they say, one man and one woman had eaten an apple!
-- p. 47, 53-4
|And (Moses) beheld many lands; and each land was called
earth, and there were inhabitants on the face thereof. And it came
to pass that Moses called upon God, saying: Tell me, I pray thee,
why these things are so, and by what thou madest them?... And the
Lord God said unto Moses: For mine own purpose have I made these
things. Here is wisdom and it remaineth in me... And worlds
without number have I created; and I also created them for mine
own purpose; and by the Son I created them, which is mine Only
Begotten... But only an account of this earth, and the inhabitants
thereof, give I unto you. For behold, there are many worlds that
have passed away by the word of my power. And there are many that
now stand, and innumerable are they unto man; but all things are
numbered unto me, for they are mine and I know them.
-- Moses 1:29-31,33-35
|The book ascribed to Matthew says there was darkness over all
the land from the sixth hour unto the ninth hour; that the veil of
the temple was rent in twain from the top to the bottom; that
there was an earthquake; that the rocks rent; that the graves
opened; that the bodies of many of the saints that slept arose and
came out of their graves after the resurrection, and went into the
holy city and appeared unto many. Such is the account which this
dashing writer of the book of Matthew gives, but in which he is
not supported by the writers of the other books.
The writer of the book ascribed to Mark, in detailing the circumstances of the crucifixion, makes no mention of any earthquake, nor of the rocks rending, nor of the graves opening, nor of the dead men walking out. The writer of the book of Luke is silent also upon the same points. And as to the writer of the book of John, though he details all the circumstances of the crucifixion down to the burial of Christ, he says nothing about either the darkness, the veil of the temple, the earthquake, the rocks, the graves, nor the dead men.
Now if it had been true that those things had happened, and if the writers of these books had lived at the time they did happen, and had been the persons they are said to be, namely, the four men called apostles, Matthew, Mark, Luke, and John, it was not possible for them, as true historians, even without the aid of inspiration, not to have recorded them. The things, supposing them to have been facts, were of too much notoriety not to have been known, and of too much importance not to have been told.
Strange indeed that an army of saints should return to life,
and nobody know who they were, nor who it was that saw them...
But... these saints are made to pop up, like Jonah's gourd in the
night, for no purpose at all but to wither in the morning. Thus
much for this part of the story.
|And it came to pass in the thirty and fourth year, in the
first month, on the fourth day of the month, there arose a great
storm, such an one as never had been known in all the land. And
there was also a great and terrible tempest; and there was
terrible thunder, insomuch that it did shake the whole earth as if
it was about to divide asunder... behold, the whole face of the
land was changed, because of the tempest and the whirlwinds, and
the thunderings and the lightnings, and the exceedingly great
quaking of the whole earth;... And many great and notable cities
were sunk, and many were burned, and many were shaken till the
buildings thereof had fallen to the earth...And it came to pass
that when the thunderings, and the lightnings, and the storm, and
the tempest, and the quakings of the earth did cease-- for behold,
they did last for about the space of three hours... and then
behold, there was darkness upon the face of the land. And it came
to pass that it did last for the space of three days that there
was no light seen; and there was great mourning and howling and
weeping among all the people continually; yea, great were the
groanings of the people, because of the darkness and the great
destruction which had come upon them.
-- 3 Nephi 8:5,6,12,14,19,23
And when Nephi had brought forth the records, and laid them
before him, he (Jesus) cast his eyes upon them and said: Verily I
say unto you, I commanded my servant Samuel, the Lamanite, that he
should testify unto this people, that at the day that the Father
should glorify his name in me that there were many saints who
should arise from the dead, and should appear unto many, and
should minister unto them. And he said unto them: Was it not so?
And his disciples answered him and said: Yea, Lord, Samuel did
prophesy according to thy words, and they were all fulfilled. And
Jesus said unto them: How be it that ye have not written this
thing, that many saints did arise and appear unto many and did
minister unto them? And it came to pass that Nephi remembered that
this thing had not been written. And it came to pass that Jesus
commanded that it should be written; therefore it was written
according as he commanded.
| The resurrection of a dead person from the grave, and his
ascension through the air, is a thing very different, as to the
evidence it admits of, to the invisible conception of a child in
the womb. The resurrection and ascension, supposing them to have
taken place, admitted of public and ocular demonstration, like
that of the ascension of a balloon, or the sun at noonday, to all
Jerusalem at least. A thing which everybody is required to
believe, requires that the proof and evidence of it should be
equal to all, and universal; and as the public visibility of this
last related act was the only evidence that could give sanction to
the former part, the whole of it falls to the ground because that
evidence never was given. Instead of this, a small number of
persons, not more than eight or nine, are introduced as proxies
for the whole world, to say they saw it, and all the rest of the
world are called upon to believe it. But it appears that Thomas
did not believe the resurrection; and, as they say, would not
believe without having ocular and manual demonstration himself. So
neither will I; and the reason is equally as good for me, and for
every other person, as for Thomas.

|And now it came to pass that there were a great multitude
gathered together, of the people of Nephi... And they were also
conversing about this Jesus Christ, of whom the sign had been
given concerning his death... And it came to pass,... they cast
their eyes up again towards heaven; and behold, they saw a Man
descending out of heaven; and he was clothed in a white robe; and
he came down and stood in the midst of them; and the eyes of the
whole multitude were turned upon him... And it came to pass that
he stretched forth his hand and spake unto the people, saying:
Behold, I am Jesus Christ, whom the prophets testified shall come
into the world... And it came to pass that the Lord spake unto
them saying: Arise and come forth unto me, that ye may thrust your
hands into my side, and also that ye may feel the prints of the
nails in my hands and in my feet, that ye may know that I am the
God of Israel, and the God of the whole earth, and have been slain
for the sins of the world. And it came to pass that the multitude
went forth, and thrust their hands into his side, and did feel the
prints of the nails in his hands and in his feet; and this they
did do, going forth one by one until they had all gone forth, and
did see with their eyes and did feel with their hands, and did
know of a surety and did bear record, that it was he, of whom it
was written by the prophets, that should come.
