You ask for some way of completely eradicating irritability. The inclination to irritability is given us to use against sin, and we were never meant to use it against our fellow men. When we do, we act contrary to our true nature.
Wouldest thou learn words of thanksgiving? hearken unto the Three Children, saying, 'We have sinned, we have transgressed. Thou art righteous, O Lord, in all that thou hast done unto us, because thou hast brought all things upon us by a true judgment.'(4) For to confess one's own sins, this is to give thanks with confessions unto God: a kind of thing which implies one to be guilty of numberless offenses, yet not to have the due penalty exacted. This man most of all is the giver of thanks.
How harmful is the praise of man! Even though a person may have done something worthy of praise, when he enjoys the sound of praise he is already deprived of future glory, according to teachings of the holy fathers.
For not only are spiritual riches and heavenly gifts received from God, but earthly and material possessions also proceed from His bounty, that He may be justified in requiring an account of those things which He has not so much put in our possession, as committed to our stewardship. God’s gifts, therefore, we must use properly and wisely, lest the material for good work should become an occasion for sin.
Monasticism itself is a perpetual labor of conquering passions and uprooting them in order that, being in a pure and immaculate state, one may preserve oneself before the face of God. This, then, is your task! Give your attention to it, and direct all your powers towards it.
For by prayer we obtain the divine favor, by fasting we extinguish the concupiscences of the flesh, by almsgiving sins are redeemed (Dan. iv. 24); and by all three together, the image of God is renewed in us, provided that we are ever ready in His praise, eager without ceasing for our own purification, and disposed at all times to assist our neighbor.
Apostolic teaching, Beloved, exhorts us that we put off the old man with his deeds (Eph. iv. 22; Col. iii. 9), and renew ourselves from day to day by a holy manner of life. For if we are the temple of God, and if the Holy Spirit is a Dweller in our souls, as the Apostle says: You are the temple of the living God (II Cor. vi. 16); we must then strive with all vigilance that the dwelling of our heart be not unworthy of so great a Guest.
And consider the reward how great! 'That ye be like your Father which is in the heavens.' So then you have been deprived of nothing, yea, you have been a gainer: you have received no wrongs, rather you have been crowned; in that you are become better disciplined in soul; are made like to God; are set free from the care of money; are made possessor of the kingdom of heaven. All these things therefore taking into account, let us restrain ourselves in injuries, beloved, in order that we may both be freed from the tumult of this present life, and cast out all unprofitable sadness of spirit, and may obtain the joy to come; through the grace and loving kindness of our Lord Jesus Christ, with Whom to the Father and the Holy Spirit be glory, power, honor, now, henceforth, and for ever and ever. Amen.
Do not pray for the fulfillment of your wishes, for they may not accord with the will of God. But pray as you have been taught, saying: 'Thy will be done in me' (Luke 22.42). Always entreat Him in this way, that His will be done. For He desires what is good and profitable for you, whereas you do not always ask for this. Often when I have prayed, I have asked for what I thought was good, and persisted in my petition, stupidly importuning the will of God, and not leaving it to Him to arrange things as He knows is best for me, But when I have obtained what I asked for, I have been very sorry that I did not ask for the will of God to be done, because the thing turned out not to be as I thought.
If a messenger brings an imperial or princely document to a subject citizen, the citizen does not examine the life of the bearer, whether he is rich or poor, righteous or sinful, but listens carefully to what he reads. If anyone has not heard him, he asks someone who has. So, if you have such enormous respect for an earthly ruler, how necessary it is to listen to us priests, here where the Creator of the heavenly powers speaks through us sinners.
Do not leave the Church, for there is nothing mightier than She; She will never grow old and will always bloom; thus the Scriptures, showing Her durability and stability, calls Her a mountain.
The enemy constantly endeavors to awaken in the abyss of the human heart a great turmoil about trifles. This is one of his tricks to blind our soul to the sun of truth, Christ our Lord, hidden in the heart's core of every one of our neighbors.
