    You are welcome to your theology, but some of this is very Lutheran, and as such it shouldn't be passed
    off as Christianity per se. A position is not non-Christian just because it is not Lutheran. I should add
    that you are using a very different notion of grace as well. Grace is what is given in redemption, not in
    creation. To claim that grace is what is given in creation is to adopt a tenet of Pelagianism, and that
    shouldn't be passed off as traditional Christianity.

    But all these lines are so arbitrary. Given molecule-to-man macroevolution, then if it is sufficient for
    Christ to reconcile all things to Himself by becoming a human, then He could have reconciled all things
    things to Himself by becoming any material thing. (Why limit it to "organic" connection?? Why not
    material connection? He has no organic connection to the molecules on Neptune. Are they lost forever?) If
    not, then why does full reconciliation only work if He becomes man? The arbitrariness of "organic" is what
    is so blatant. Why not choose any other relationship? For some reason, to heal the plant kingdom it is not
    enough that Christ assumes the same matter that was previously shared by the entire biosphere, He must
    have an organic relation to them. Why stop there? Why not a kingdom relation, or phylum relation, or
    class, or order, etc.? If He had to become a human to reconcile humans, then why must He not become a bat
    to save bats, and a cow to save cows? You pick the lines where it suits you. That's fine, but just up and
    say that your prior belief in macroevolution drives the whole thing; don't claim to derive it from special
    revelation.

    I hope we're clear that "not surprising" here does not mean "supports"; it just means "compatible", (for
    reasons I explained in my previous post) unless you want to say something stronger.

    Call it what you will. The fact is that there cannot be transmission of unacquired [genetic]
    characteristics. Whatever is transmitted must be already possessed at least at the genetic level.

    There's science for you, appealing to luck. Science cannot appeal to direct intervention by God; but
    appeals to Lady Luck are just fine. But with respect to your claim about natural selection, I believe you
    are sorely mistaken. I agree that since non-humans are not moral agents, there is no sense in which they
    "deserve" to be selected. And there is no doubt that random genetic drift occurs, pleiotropy, heterozygous
    dominance, meiotic drive and other factors work against the maximization of optimality. But in general,
    the fitter survive, and the gene frequency of fitter traits increases over time. If you deny this, you are
    denying a fundamental tenet of macroevolution by natural selection. It is not due to luck that mammals
    survived the dinosaurs. That is utter nonsense. That is like claiming it was a miracle, or that there is
    simply no scientific explanation for it. Was it just by luck that thick-coated animals out-survived
    thin-coated animals in the artic? Was it just by luck that camouflaged animals out-survived their
    uncamouflaged relatives? If you were to be consistent with your methodological naturalism, you would give
    up this appeal to luck, and begin looking for features about mammals that made them more suited to survive
    those conditions than were the dinosaurs. For a discussion of fitness and natural selection, see, for
    example, Elliott Sober's The Nature of Selection: Evolutionary Theory in Philosophical Focus (University
    of Chicago Press, reprint ed. 1993).

    I briefly discussed its content previously, but I'll address it directly. I'm not sure who your phantom
    opponent is here, this worshiper of the "conventional beneficent God of philosophical theism"; I'm not
    even sure what you mean by this phrase, since you don't spell it out. Therefore, I cannot say anything
    about whether such a view of God creates theodicy dilemmas or not.

    I'm not using "support" as if it meant logical implication. I'm using it in the abductive sense. If a
    piece of evidence does not increase the likelihood of a hypothesis over competing hypotheses, then it does
    not support that hypothesis.

    That just begs the question. I think that with what we *know* today (not just what we have assumed) about
    Scripture and natural science, it is quite possible to have a coherent Christian theology that takes the
    real world seriously and does not include some form of macroevolution. You have not shown that any
    contemporary Christian theology that does not include some form of macroevolution is "incoherent", unless
    "incoherent" just means that it does not include some form of macroevolution.

    I'm not going to debate exegesis with you. But I will say that I find the passages describing God as
    unchanging much more explicit about the nature of God with respect to immutability than I find any passage
    describing the actions of the Logos. If God creating is not incompatible with divine immutability, then
    neither is any other act of any person of the God-head. Explaining this would take me into a discussion of
    God's relation to time, a discussion I don't want to get into in this context.

    You are right; I am not sure I understand your point. First, you admit that not all miracles occur in
    salvation history. Then you question the distinction between salvation history and another realm of
    history. Then you say that nature miracles in the NT point to the creator who operates all the time in the
    world by natural processes. (Later you say that the NT miracles point not to Christ but to Jesus.) Then
    you claim that a miraculous creation event would not point out the creator in this way. I have no idea
    what you mean by "The NT takes for granted . . . not of observation." Then you repeat your claim about NT
    miracles. Then you ask what the sign value of a miraculous creation of life in the beginning would be.
    Apparently, your point is, I take it, that a miraculous creation in the beginning would have no sign
    value. But first, as I said before, not all direct divine actions need have sign value. Surely you believe
    that the creation event was a direct divine act, but you don't require of it that it had sign value.
    Therefore, there is no reason to require of any direct divine event after the first moment of creation
    that it have a sign value. Second, if it did have sign value, it needn't be a tautology. It could just as
    easily be, "to point out the presence of the God who operates all the time in the world by natural
    processes." The Genesis passage clearly express the intimacy with which God fashioned humans, for example.

    Agreed. The source is previous scientific knowledge or methodological naturalism, not Scripture; that was
    my point.

    Mechanism, mechanism, mechanism. That is the issue. Most Christians do not deny that humans were formed by
    the dust of the earth; the debate involves the mechanism: by what means did fashion humans from dust? (By
    macroevolution or directly? With direct divine action or without it? etc. and every position in between.)
    Only those who endorse de novo creation are at odds (in my view) with these passages. All the other
    positions (viz-a-viz *mechanism*) are quite consistent with these passages, for the passages say
    absolutely nothing about whether the mechanism was within the bounds of natural laws. To read into that
    passage "completely by natural causes and natural processes" is to read into that passage something that
    is not there, even if it is true.
