A review of contemporary theological publications that concern a variety of different issues lets one notice a certain regularity, i.e. frequent referring to complementary thinking or the principle of complementarity in the theological reflection. In the present article first the fact is shown that referring to complementary thinking has a significant effect on the quality and versatility of theological thinking. Complementarity that is a fruit of the Church’s Catholic character may be a way of reaching the Catholic fullness and a peculiar antidote against the threat of reducing all the wealth of the mystery of faith to some individual aspect only. In the second part a distinct presence of complementary thinking in various areas of the contemporary theological reflection is pointed to.
