Life of a citizen is – at least from Christian point of view – a road that leads to God and on which at least two not excluding realities can be met: political and religious. The Christian should engage in the political life and at the same time follow the appropriate moral system. The entire political activity must be understood in moral terms because it is centered on human life and actions which might be good as well as bad. The politics cannot be practiced according to the rules of ideology of effectiveness and success, without taking universal values and moral laws into account. Following ethical principles within the policy guarantees the proper functioning of the state and the protection of individual rights. Realizing the potential risks in the field of politics, we have to talk about the need for moral formation for all fully participating in political life. This formation is necessary to infiltrate the world of politics with the spirit of service to the common good.
