The opposite of realism is not idealism, but moralism. This also describes a central problem of political philosophy: The hubris of believing that both political decisions could be derived from morality and that political processes could be deduced from it. Instead, political processes follow their own rules, which a political theory has to integrate, otherwise it becomes unrealistic. However, models of cooperation are necessary so that morality and politics do not diverge as two separate systems. The concept of sacramentality in the Catholic Church combines a ritual external event with an inner reality of salvation. Although sacraments are an object of faith, their validity does not depend on the faith of the participating people - neither the minister nor the recipient. Instead, the sacrament must be performed in a prescribed ceremony. The faith of the individual believers makes the sacramental event individually fruitful. Sacramental efficacy thus combines a formally objective and a personally subjective performance. Both acts are based on the same faith, but have different ways of legitimization. Moral-political realism could be understood in the same way. The same morality leads to an extraction of a personally subjective and a formal realization. The individual moment is a direct deduction of morality, while the formal moment mediates moral claims with institutional, social and traditional elements. The formal moment guarantees, for example, balancing functionality, which can find its goal in subjective justice in the personal moment.
