The ties between the Church, Christian tradition and the (post)modern society are being weakened, while globalization trends tend to prevail. Therefore it is necessary to show common values and goals. One of them is the problem of an individual's identity and the sense and aim of his existence. Christian antropology, deeply rooted in the Bible, reveals the imago Dei idea, whose vital consequence is natural law. It originates from the Revelation and determines fundamental and universal morality. It should not be looked upon as just a set of rules and norms, but also as one's ability to dei ne his identity in a given period and circumstances. Consequently, it should be an ultimate criterion of justice (truth) in the process of enacting positive law. Although human mind is able to recognize and accept natural law (which is proved by our ethical heritage), it should also be understood and interpreted in the light of the grace. Thus natural law (ius naturale) and human conscience (conscientia) are important 'meeting points' and areas of cooperation between the Church and today's society.
