Here is the whole chapter with the parts of interest highlighted. Thomas Paine summarises why he believes revelation to humans is an erroneous belief and that the signs of God are in his creation and that Deism is the original religion and is not in want of later mythology. The conclusions of his arguments are easily criticised or proven wrong but the perspective of a Deist is a refreshing change to the recycled garbage we hear from other kinds of theists. Also, he ends the first part of his book admirably by emphasising freedom of religion.
"HAVING now extended the subject to a greater length than I first intended,
I shall bring it to a close by abstracting a summary from the whole.
"First, That the idea or belief of a word of God existing in print, or in
writing, or in speech, is inconsistent in itself for the reasons already
assigned. These reasons, among many others, are the want of an universal
language; the mutability of language; the errors to which translations are
subject, the possibility of totally suppressing such a word; the
probability of altering it, or of fabricating the whole, and imposing it
upon the world.
Secondly, That the Creation we behold is the real and ever existing word
of God, in which we cannot be deceived. It proclaimeth his power, it
demonstrates his wisdom, it manifests his goodness and beneficence.
"Thirdly, That the moral duty of man consists in imitating the moral
goodness and beneficence of God manifested in the creation towards all his
creatures. That seeing as we daily do the goodness of God to all men, it
is an example calling upon all men to practise the same towards each
other; and, consequently, that every thing of persecution and revenge
between man and man, and every thing of cruelty to animals, is a violation
of moral duty.
"I trouble not myself about the manner of future existence. I content
myself with believing, even to positive conviction, that the power that
gave me existence is able to continue it, in any form and manner he
pleases, either with or without this body; and it appears more probable to
me that I shall continue to exist hereafter than that I should have had
existence, as I now have, before that existence began.
"It is certain that, in one point, all nations of the earth and all
religions agree. All believe in a God. The things in which they disgrace
are the redundancies annexed to that belief; and therefore, if ever an
universal religion should prevail, it will not be believing any thing new,
but in getting rid of redundancies, and believing as man believed at
first. Adam, if ever there was such a
man, was created a Deist; but in the mean time, let every man follow, as
he has a right to do, the religion and worship he prefers."
