In the market economy, founded on the principle of the maximum profit and of the direct competition it is difficult to apply the doctrine of gratuitousness, which in the economical sphere, is an unjustified loss. And yet, Antoine Sondag says that people, except the material needs, which economy can satisfy, has also relational and spiritual needs. That is why economy has to accept that it is limited. Through gifts there are created relationships and through gratuitousness can be built a society; economy can not create society but requires it. Only by extending this sector of gift and of gratuitousness, Christians can promote the equilibrium in society and in market.
