The author of the article puts forward methodological guidelines important in the process of deriving anthropological truth from Christology. A Christological doctrine along with its modern reinterpretation is presented in the text. It is a hermeneutical key to conduct a research on the earthly history of the Incarnated described in the Gospels. The fact of the primacy of Christology over anthropology is highlighted, as well as the significance of the statement that the Word became man ‘for us and for our salvation’. In Christ we receive not direct, but indirect manifestation of a human. One should regard both the Son who became man and the Redeemer who, being exactly a man himself, redeems sinners. Therefore, the Incarnated Word as well as a man should be regarded in a dynamic way, taking into account the time dimension. The patristic axiom Quod non est assumptum non est sanatum (‘what is not assumed is not saved’) can be also referred to particular stages of human life redeemed by Christ.
