Theological anthropology is the branch of systematic theology that treats the doctrine of man—his origin, nature, constitution, dignity, fall, and destiny—as God has revealed it in Scripture. It answers the question of the psalmist, “What is man, that thou art mindful of him?”—not from the speculations of philosophy or the findings of natural science alone, but from the Word of the One who made him. Its great affirmations are these: that man was created by the immediate act of God, formed of the dust of the ground as to his body and given a living soul by the inbreathing of God; that he was made in the image and likeness of God, crowned with a dignity above all other earthly creatures, endowed with reason, will, affections, and moral knowledge, set as God’s vicegerent over the creation; that he was created male and female, both bearing the divine image, ordained for fellowship, fruitfulness, and dominion; that he is a unity of body and soul, neither a beast nor a disembodied spirit; that he was created upright, in true righteousness and holiness, under a covenant with his Maker; that by the fall he plunged himself and his race into sin, guilt, corruption, and death; and that he is the object of God’s redeeming purpose in Christ, the second Adam, in whom the ruined image is restored. A sound theological anthropology guards man’s unique dignity against every reduction that would make him a mere animal or machine, and guards man’s creaturely dependence against every exaltation that would make him autonomous or divine. It teaches him to know himself truly—as the image-bearer he was, the sinner he has become, and the redeemed he may be in Christ—for the knowledge of God and the knowledge of self are bound inseparably together.
Webster 1828 defines ANTHROPOLOGY as a discourse upon human nature; the doctrine of the structure and nature of man.
ANTHROPOLOGY, n. — A discourse upon human nature; the doctrine concerning the structure, constitution, and nature of man.
MAN, n. — ...Mankind; the human race; the whole species of human beings; beings distinguished from all other animals by the powers of reason and speech, and by their moral faculties.
Psalm 8:4-5 — "What is man, that thou art mindful of him? and the son of man, that thou visitest him? For thou hast made him a little lower than the angels, and hast crowned him with glory and honour."
Genesis 1:27 — "So God created man in his own image, in the image of God created he him; male and female created he them."
Genesis 2:7 — "And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul."
Psalm 139:14 — "I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works."
Theological anthropology is corrupted at two poles—the reductionism that makes man a mere evolved animal or biochemical machine, and the exaltation that makes him autonomous, self-defining, and effectively divine.
The first great corruption of the doctrine of man is reductionism—the denial of his unique dignity as the image-bearer of God. Secular evolutionary naturalism reduces man to a highly developed animal, the product of blind chance and survival, differing from the beasts in degree but not in kind; and materialist science reduces him further to a biochemical machine, his thoughts mere neural firings, his soul a superstition, his will an illusion. On these views there is no image of God, no immaterial soul, no moral accountability, no eternal destiny—only matter in motion. This strips man of his glory and, in the end, of every ground for his rights, his reason, and his worth.
The opposite corruption exalts man into the place of God. The modern dogma of autonomy makes the self sovereign—the source of its own meaning, the definer of its own truth, the author of its own identity, accountable to no Creator. Man becomes, in his own imagination, the measure of all things, free to remake even his own nature according to his will. This is the original temptation, ‘ye shall be as gods,’ raised to a creed. A sound theological anthropology answers both errors at once: man is neither a mere animal nor a god, but the image-bearing creature of God—higher than the beasts because he bears the divine image, lower than his Maker because he is a dependent creature, fallen by sin yet the object of redeeming grace. To know man truly, one must begin with the God whose image he bears, for the knowledge of self and the knowledge of God are inseparably joined.
The field is named from anthrōpos (man); its substance rests on man as ’ādām (man, from the ground) made a living nephesh (soul) in the image of God.
"A sound theological anthropology guards man’s dignity as God’s image against reduction, and his dependence against exaltation."
"‘What is man?’—the doctrine answers from the Word of his Maker, not the speculations of philosophy alone."
"The knowledge of self and the knowledge of God are joined; right anthropology begins with the God whose image man bears."
