Theists are human? Theists usually claim they know who God is and which religion is the right one and a number of related claims. Those claims are such that they would require omniscience and omnipotence in order to be made justly.
here is where i separate the definition of 'know'
know
1.
to perceive or understand as fact or truth; to apprehend clearly and with certainty: I know the situation fully.
2.
to have established or fixed in the mind or memory: to know a poem by heart; Do you know the way to the park from here?
3.
to be cognizant or aware of: I know it.
4.
be acquainted with (a thing, place, person, etc.), as by sight, experience, or report: to know the mayor.
5.
to understand from experience or attainment (usually followed by how before an infinitive): to know how to make gingerbread.
in the scientific aspect it is 'to perceive or understand as fact or truth; to apprehend clearly and with certainty'
which there is wiggle room in this definition with the use of the term 'perceive'
but the sense that most theist use it is 'be acquainted with (a thing, place, person, etc.), as by sight, experience, or report'
(although i would let you argue that most theist miss-use the term in the first sense)
so in this sense no omniscience and omnipotence is needed..
one must just study God to be familiar with him, to 'know' him is to have ones own experiences confirm what is learned of him.
So theists are actually claiming they have superhuman qualifications.
And that seriously detracts from their humanness.
again this is where your definitions are conflicting with what is true..
you are claiming they must have superhuman qualifications, and since you know there is no such thing as superhumans you disqualify every theist..
hehe..after i wrote that i thought that you are already doing that..
Sure. The moment someone claims that "God is a myth," I point out that they are presuming themselves to be omniscient and omnipotent.
fair enough..
(my own personal philosophy says that in order for something to be true it must apply equally to both sides of the argument)
One cannot claim that one knows God, and then claim one is a fallible human, and then still think one is being consistent.
'know' when applied to a person/personage is not the same as 'know' as applied to the physical world,
I can 'know' a person and someone else can 'know' someone differently, this does not mean that either is wrong,(doesn't necessarily mean that either is right also..)
where as in the physical world (using this term in the scientific aspect) knowledge is empirical,IE water boils at X temperature, electrons have X mass, etc..
so a person can claim to 'know' God and still be fallible..there is no omniscience and omnipotence needed/required, also with this 'know' there is no 'one correct' religion..
