    Actually, factor analysis does not interpret the result ("tell you what it
    is"). It simply attempts to reduce data comprised of many variables, to fewer
    variables, which then must be interpreted based upon the investigators
    knowledge of the problem. There is also another step (beyond reducing the
    data) which is called "rotation". In this step the eigenvectors are rotated
    to change the way they project upon the original variables so that the results
    are<more>interpretable. The rotation and interpretation can be quite
    subjective and thus must be very carefully examined. Many statisticians have
    problems with rotation. I think it can be useful, but only if done very
    carefully. I haven't seen enough details in the work being presented to judge
    it(for the devil is in the details). For example, the selection of the number
    of factors in often based upon variance (only extract up until a certain
    percent of variance is explained). This number can make a big difference in
    certain cases...my point is that the analysis is not so cut and dry as it is
    being portrayed. I'm seeing none of the details
    necessary for a replication (even in the peer reviewed article), only bold
    claims about the implications of the results. An association does not
    necessarily imply causation, but this is not even mentioned.

    BUT THE BOTTOM LINE (IMHO) IS:

    Finally, it seems to me that this work is completely naturalistic. The
    Bible is reduced (a priori) to complete metaphor...including any
    of the miracles in scripture. His definition of God is not consistent with
    the God of Christianity. He simply claims to have found a way to
    explain all the miracles of the Bible in a scientific, naturalistic way. The
    way He discusses the Bible is not consistent, IMHO, with Christianity in any
    way, shape, or form and reveals a naturalistic approach to God. These
    findings could perhaps be used as another example of Romans 1 (God's general
    revelation through creation).

    To Hammond: If you are on this list then you agree with a statement saying
    you confess the Triune God affirmed in the Nicene and Apostle's creeds. Based
    only upon those creeds, the God of Christianity is distinct from the God of
    any other world religion. Not only that, but His Son, Jesus, provides the
    only possible reconciliation to this God (based upon Christ's statements).
    He, in His great love, provides all of humanity with acceptance through
    Christ if they but accept what is made available to them. I do the science
    that I do as a Christian who loves God because He first loved me. What do the
    findings you present tell us about the God of Christianity?

    Just my two cents...(sorry to keep the discussion going...I'll stop now)

    For His Glory,

    VDC
