The author in his article, written in terms of a general theory of law, reasons how the canon law performs a duty to guarantee freedom for a Christian in the Church, as the secular law guarantees -or more precisely: should guarantee-the freedom of men in civil society. Is the Christian who stands committed, not only to the secular, but also to the canon law, freer - or on the contrary less free - than other people? A significant part of this question is given by the close relationship of law norms and moral norms in the juristic regulations of the Church that is closely connected to its typical differentiation in the canon law of the outer and inner field (forum externum a internum). Naturally this also depends on the concept of freedom that is even within law theory frequently understood in different meanings. According to the author, canon law establishes, more clearly than morality, the code of conduct for Christians in the sphere where it touches the normative 'framework of morality'; and by this is the space for free decisions by its members unambiguously defined.
