Christian religion is not a certain philosophic system, about which learned men, trained in metaphysical studies, argue and then either espouse or reject, according to the opinion each one has formed. It is faith, established in the souls of men, which ought to be spread to the many and be maintained in their consciousness.
There are truths in Christianity that are above out intellectual comprehension, incapable of being grasped by the finite mind of man. Our intellect takes cognizance of them, becomes convinced of their reality, and testifies about their supernatural existence.
Christianity is a religion of revelation. The Divine reveals its glory only to those who have been perfected through virtue. Christianity teaches perfection through virtue and demands that its followers become holy and perfect. It disapproves of and opposes those who are under the influence of the imagination. He who is truly perfect in virtue becomes through Divine help outside the flesh and the world, and truly enters another, spiritual world; not, however, through the imagination, but through the effulgence of Divine grace. Without grace, without revelation, no man, even the most virtuous, can transcend the flesh and the world.
God reveals Himself to the humble, who live in accordance with virtue. Those who take up the wings of the imagination attempt the flight of Ikaros and have same end. Those who harbor fantasies do not pray; for he that prays lifts his mind and heart towards God, whereas he that turns to fantasies diverts himself. Those who are addicted to the imagination have withdrawn from God’s grace and from the realm of Divine revelation. They have abandoned the heart in which grace is revealed and have surrendered themselves to the imagination, which is devoid of all grace. It is only the heart that receives knowledge about things that are not apprehended by the senses, because God, Who dwells and moves within it, speaks within it and reveals to it the substance of things hoped for.
Seek God daily. But seek Him in your heart, not outside it. And when you find Him, stand with fear and trembling, like the Cherubim and the Seraphim, for your heart has become a throne of God. But in order to find God, become humble as dust before the Lord, for the Lord abhors the proud, whereas He visits those that are humble in heart, wherefore He says: “To whom will I look, but to him that is meek and humble in heart?”
The Divine Light illumines the pure heart and the pure intellect, because these are susceptible to receiving light; whereas impure hearts and intellects, not being susceptible to receiving illumination, have an aversion to the light of knowledge, the light of truth; they like darkness… God loves those who have a pure heart, listens to their prayers, grants them their requests that lead to salvation, reveals Himself to them and teaches the mysteries of the Divine nature.
