The aim of the paper is to implement a new and so far unfamiliar theoretical perspective into Polish communication science. Although the functional theory of political discourse discussed here originated on the ground of American empiricism, it aspires to be perceived as an international theory which may be successfully applied in analyses of political messages in various countries. Thus, the authors of presented paper aim not only at transporting onto Polish humanities premises and theoretical presumptions but also at verifying their adequacy in Polish political stage based on comparative analysis obtained from research performed by American and Israel scholars.
