Our questions refer to the connection among body and sexuality conceptions in different moments of Christian-catholic history as well as to the place occupied by those conceptions within a broader culture, establishing a parallel to historic periods. We face a few connected links that remain strongly interacted among themselves such as: life, death, fear and sin. In order to accomplish our analyses we rely on the thoughts of authors that have shown the meanings of body and sexuality as cultural constructions. Through the available literature we search to verify how fear of death, recognized as a characteristic of human nature, is expressed in the conceptions of body and sexuality shown by Christian-catholic tradition; also how this fear is perceived today and how it reflects upon the conceptions of body and sexuality nowadays. The research pointed to the conclusion that one of the possible reasons why Christianity-Catholicism invests so much energy in the control of sexuality and the body is that this represents an area of confrontation of fear of death. Such design is echoed in the wider culture, leading people to join, albeit partially, for so long, the ideal Christian-Catholic control of sexuality and the body.
