The Holy Scripture is the domain of Wisdom, Word and Spirit, of God in the Trinity: in it He clearly manifests Himself: “The Words that I speak unto you, they are spirit, and they are life, said the Lord.”
The writings of the Holy Fathers are again the expression of the Mind, Word and Spirit of the Holy Trinity, in which the spirit of the higher class (spiritually speaking) of mankind has largely participated; the writings of ordinary worldly men are the expression of the fallen spirit of men, with all their sinful attachments, habits and passions.
In the Holy Scriptures we see God face to face, and ourselves as we are. Man, know thy self through them, and walk always as in the presence of God.
As you are aware, man, in his words, does not die; he is immortal in them, and they will speak after his death. I shall die, but shall speak even after my death.
How many immortal words are in use amongst the living, which were left by those who have died long ago, and which sometimes still live in the mouths of a whole people!
How powerful is the word even of an ordinary man! Still more so is the Word of God: it will live throughout all ages, and will always be living and acting.
As God is the creative, living and life-giving Wisdom, therefore those greatly sin who, by the thoughts of their spirit, turn aside from the Wisdom of the Trinity and occupy themselves with material, perishable things, thus materialising their spirit itself.
Especially do those sin who, during Divine Service in church or during their prayers at home, entirely turn aside in their thoughts from God and allow their minds to wander in different places outside the church. By doing so they greatly offend God, upon Whom on such occasions our minds should be fixed.
