i don't recall we were even discussing the topic of atonement. As for the resurrection, lets look more carefully at what paul says, in that same chapter of 1 Corinthians you cited earlier.
40 There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another.
41 There is one glory of the sun, and another glory of the moon, and another glory of the stars: for one star differeth from another star in glory.
42 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption:
43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:
44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
45 And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
46 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
47 The first man is of the earth, earthy; the second man is the Lord from heaven.
48 As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly.
49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
i might be wrong here but it seems to me that a body which is not flesh and blood is not likely to be a physical body. i can't say i'm entirely sure what paul is saying here but it sounds a lot like the views of Shaykh Ahmad Ahsai, a forerunner to our own religion, who held that people had both physical and spiritual bodies as well as physical and spiritual souls and only the latter would participate in the resurrection. i give a lot of credence to paul's account because he is the only writer in the new Testament that claims to have seen the resurrected jesus. All the other accounts are third person hearsay.
