The portal «Two Cities» describes the existence of two warring cities: the City of God and the city of man. Such a division of the human race has nothing visible, visual, psychological. The enmity of the City of Heaven and the city of the earth derives from the fate of the soul, each of which by its own will belongs to the city of God or the city of man.
Two cities — The City of God and the City of Man — contend one with each other from the beginning of human history and is due to contend till the end of times. These two cities have separate origin and destined end. There cannot be any compromise at any point, in any society or any soul between the City of God and the City of Man.
First reality
The first reality is the only truly existing reality of a man created and saved by God. A Christian stands before God in the first reality and is a citizen of the City of God.
Next to the first reality is posited an inauthentic and accidental second reality of human error, fantasy and rebellion against God.
The City of God
The human race is not one-ness or «all-humanity», but is divided into two societies: those that live by man and those who live by God. These divisions St. Augustine called two cities, that is, two societies of people, of which one is destined to reign forever with God, and the other to be subjected to eternal punishment with a devil.
Religion of salvation
The religion of salvation consists in faith in Jesus Christ as the Savior. It is a revealed otherworldly religion that is established by God for men to be obedient to God and for the salvation of the soul. To saved you need the knowledge of the true God and the right faith of Him, and secondly, life by faith and good deeds. For salvation, one must not only have Orthodox Faith but also profess it (further...).
Order
Order is the perfect dispensation of all things, preserved by the Providence of God. Order is the key concept of Christian philosophy synonymous with the first reality. Despite human pride and stupidity, the Divine order in the world is indestructible, because the two Cities will have opposing ends: the City of God will end in Divine glory and the city of man will end in Divine condemnation.
Truth
Truth is the First reality: the world created by God, the world of the fallen and the cursed, the world saved by Christ.
Universal
Universal is the Divine law, order, a real and no mere nominal unity. Universal can by nature be predicated of many subjects.
Individual
An individual is a concept that depicts and outlines universal in a subject.
Man
Man is by nature a rational being, mortal, created by God in His image and likeness. Human nature is knowable and cannot be changed.
Faith
Faith is one of the three main Christian virtues. Faith believes in the invisible as in the visible, in the desired and expected as in the present. To be saved man needs faith in the first place. Without the right faith, it is impossible to please God.
Virtue
Virtue is the Good, the order of the soul that was created by God. Virtue has its image and foundation in God.
Sin
Sin is the evil, trespassing of the Divine law and the will of God. Sin is the conscious and disorderly violation of God's commandments and fulfillment of them as human commandments.
Cognition
Cognition is an orderly knowing of truth, that is, out of love for truth, in separate concepts, the truth of which can be verified and proven through inferences.
Search
Search is a manifestation of love for the truth when a man judges himself whether he stands in Truth or not.
The central question of human existence
The central question of human existence is: «Why am I created, not left in nothingness».
Human condition
The human condition consists of the constant discords of present life endured by every human being.
State
The state is an order of society, a monarchy, established by God in the image of His rule over everything created. The state is a just subordination of subjects to superiors.
Reason
Reason or nous is created by God, comprehends things as they are, and expresses its thoughts through intelligent speech.
Sane speech
Sane speech correctly conveys the truth, the true conclusions and what is truly meaningful. Sane speech makes dialogue possible as an expression of love for the truth.
Politics
Politics is the citizen's participation in deliberative or judicial administration. Politics is an example of God-established order. No public space can be deemed to be free of politics.
Like-mindedness
Like-mindedness is the common reason of the multitude, a political friendship. Like-mindedness is associated with things that are indispensable and affect the whole way of life.
Second reality
Next to the first reality is posited an inauthentic and accidental second reality of human error, fantasy and rebellion against God. Citizen of the city of man lives in the world of his and others' fantasies, but this does not make him free from the judgement in the First reality. No fantasy can change the fact that the man was created and saved by God.
The City of Man
The City of Man suffers from the constant discords of the present life: an opposition between good and evil, the Church and the world, between fullness and emptiness. The City of Man considers this contradiction imaginary and the citizens of this City solve it disorderly mixing good and evil.
