The icon is a true synthesis of the deeds of steadfastness in Christ, rendered through church art. Beyond the sign of verticality that it evokes and under which it creates an interdependent relationship between heaven and earth, the icon has an essential and defining role on the way in which man looks at God, from his first moments of life, but especially on the framework in which the living Creation meets its Creator. Thousands of testimonies have been recorded about the mysterious face and the existence of life in the iconographic depiction, which continues to exist today through the work of divine Grace, which makes us, in the Orthodox faith, say that the icon is more than an adapted iconographic and stylistic representation, but a lasting source of life.

           A visual imprint of the holy prototypes, located at the confluence between the Liturgical Tradition of the Church and the history of the Byzantine and post-Byzantine world, the icon also has a strong educational role, sharing with the faithful holy models of Christian living.

           The face-to-face encounter with God requires the display of the state of perfection of the divine image revealed to the Christian, who is seeking perfection. This encounter can take place only through the icon, which bears in itself a representation of the unchanging and steadfast image of God and of the saints through whom He is glorified. This is the point in which the icon reaches its role as a window to heaven, through which the true Light enters, in a consensual way, into the soul of the Christian.

         According to the iconographic plan, the mosaics of the cathedral will illustrate scenes taken from the Old and New Testament, allegorical characters, events from the life of the Saviour, of the Blessed Virgin Mary, the Holy Apostle Andrew, the Protector of Romania and other saints who, through their representation, will render the historical foundation of the Orthodox Church, and therefore the iconography of the cathedral will include:

• The Church of the Apostolic Age, rendered by the representation of the 12 Apostles

• The Church of the Patristic Age, of the Holy Fathers from the Greek, Syriac, Latin and Slavic Language Churches, the Romanian Orthodox Church, old and contemporary.

         Due to the Latin character of the Romanian Orthodoxy – underlined by the great theologian Priest PhD Prof. Acad. Dumitru Stăniloae, who states that the Romanian people are on one hand Latin, and on the other hand raised in the spirituality of the Holy Fathers of the Church, aspects that distinguish us, identity-wise, both from Westerners and from the peoples of the East, which creates a unitary spirituality that defines the existence of our nation.

       The saints to be painted in the People’s Salvation Cathedral are not purely coincidental, as behind the choice there is an extensive process of documentation made with the help of the “Mineiul”, a church book in which religious services are indicated, on months and days, through which the lives and the spiritual zeal of the saints are presented, information that serves as a pictorial rendering as deep and close as possible to their holy life.

          In addition to the saints from the universal church, the pillars of Romanian Orthodoxy, the great saints of the Romanian nation, will be represented on the walls of the cathedral. The most well-known Romanian saints will occupy an important space, in sight, in order to be closer to the faithful.

        Also, certain spaces inside the cathedral will be dedicated to lesser-known saints, but also for the painting of Romanian confessional saints from communist prisons, such as: Father Stăniloae, Father Sofian, Father Cleopa, Partenie Gherasim Iscu and others.
