"...what being created in God’s image means? I would like to know each of your views. Here is what John Calvin had to say on the matter which I agree with:
Since the image of God had been destroyed in us by the fall, we may judge from its restoration what it originally had been. Paul says that we are transformed into the image of God by the gospel. And, according to him, spiritual regeneration is nothing else than the restoration of the same image. (Colossians 3:10, and Ephesians 4:23.) That he made this image to consist in righteousness and true holiness, is by the figure synecdoche; for though this is the chief part, it is not the whole of God's image. Therefore by this word the perfection of our whole nature is designated, as it appeared when Adam was endued with a right judgment, had affections in harmony with reason, had all his senses sound and well-regulated, and truly excelled in everything good. Thus the chief seat of the Divine image was in his mind and heart, where it was eminent: yet was there no part of him in which some scintillations of it did not shine forth. For there was an attempering in the several parts of the soul, which corresponded with their various offices. In the mind perfect intelligence flourished and reigned, uprightness attended as its companion, and all the senses were prepared and moulded for due obedience to reason; and in the body there was a suitable correspondence with this internal order. But now, although some obscure lineaments of that image are found remaining in us; yet are they so vitiated and maimed, that they may truly be said to be destroyed. For besides the deformity which everywhere appears unsightly, this evil also is added, that no part is free from the infection of sin. - Calvin on Genesis The same basic point is repeated in the Commentary on Colossians: And this is what he immediately adds, that we are renewed after the image of God. Now, the image of God resides in the whole of the soul, inasmuch as it is not the reason merely that is rectified, but also the will. Hence, too, we learn, on the one hand, what is the end of our regeneration, that is, that we may be made like God, and that his glory may shine forth in us; and, on the other hand, what is the image of God, of which mention is made by Moses in Genesis 9:6, the rectitude and integrity of the whole soul, so that man reflects, like a mirror, the wisdom, righteousness, and goodness of God. He speaks somewhat differently in the Epistle to the Ephesians, but the meaning is the same. See the passage -- Ephesians 4:24. Paul, at the same time, teaches, that there is nothing more excellent at which the Colossians can aspire, inasmuch as this is our highest perfection and blessedness to bear the image of God.
Calvin states that man in Adam had been given the ability of clear and consistent thought, reason, righteousness, etc. All was lost with the fall. Adam's heirs lost these abilities and became slaves to sin. With Christ these abilities are, in a limited sense, restored. We become new creatures-reverting back to the nature of Adam, free to do God's will. This, of course in my opinion, is somewhat limited until we regain our glorified bodies. (Calvin might disagree and, is so, I could understand his reasoning.)
Augustine believed man reflects the image of God as being body, soul and spirit; and this is what is portrayed as the image of God. Calvin basically accepts Augustine's premise but it is not the main issue as to the image of God.
