What is that? Physcicalism christianity, Is it an attempt to rationalize religion? The Beauty of religion is on its irrational.
No no, none of the sort. Christian (anthropological)-physicalism (or materialism) is just the interpretation that the Bible's use of words like "soul" and "spirit" regarding human beings have been misunderstood due to philosophical tradition, and that a human being is just a body (monism) and is not comprised of both a physical body and "soul"/"spirit" (dualism) as in an immaterial substance like a ghost.
That means there is no conventional popular "afterlife" of floating around as a ghost, but rather (what the Bible definitely teaches) a physical resurrection on judgment day (a literal body for believers in Christ, but a body that is immortal and without pain, sorrow and sin).
John 5:28: "Marvel not at this: for the hour is coming, in the which all that are in the
graves shall hear his voice,
29 And shall come forth; they that have done good, unto the
resurrection of life; and they that have done evil, unto the resurrection of damnation."
Romans 8:23: "And not only
they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption,
to wit, the
redemption of our
body."
Philemon 3:21: "Who shall
change our vile
body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself."
But yes, part of religion contains things irrational or at least hard for humans to understand. But so has science discoveries that seem contradictory, irrational and difficult. An example is the difficulty in uniting quantum physics with relativity theory.
