"For the zeal of Thy house has eaten me up and the reproaches of those who reproach Thee have fallen on me" (Psalm 69:9).
The heavens are the house of God. The Church of God is the house of God. The bodies of believing people are the house of God. Wherever God is, there is the house of God; and where the house of God is, there is holiness. Men dishonor the holiness of God's house, and the royal prophet is provoked and burns with zeal. He takes upon himself all the offenses against the holy things of God, and they fall upon him like a fire that enkindles him with even more zeal.
Men desecrate the heavens when they do not believe that which God Himself revealed to mankind for the sake of their salvation. When men oppose or pervert the truth, as do the heretics, or when, of their own free will, they conceive of Christ according to their corporeal understanding, or when they have doubts about angels and saints, the Judgment, and the Eternal Kingdom of Christ, and refuse to consider the eternal punishment of unrepentant sinners - in all this and more, men attack the house of God and desecrate its holiness like savage animals. This causes zeal against the opponents and the blasphemers of God to rise in the hearts of the righteous.
In the same manner, men attack the house of God's holiness when they behave unworthily toward the Church of God, when they are negligent concerning the Church's ordinances, when they are slothful toward ecclesiastical commandments and malicious toward the servants of the Church. Again, zeal for the holiness of the house of God is inflamed in the hearts of the righteous and the devout.
Finally, the corrupting of the human body, the surrendering to passions, the service of sin, abduction, murder, brutality, drunkenness and other wicked actions, are all attacks on the holiness of God's house. It is all blasphemy against God and against man. Again, the fervor of the zealots of holiness rises up and shines as a heavenly flame before men. O my brethren, let us look at Christ's zeal for the holiness of God's house, and the zeal of the apostles and the Holy Fathers of our Orthodox Church. Let us have more zeal for our salvation than the devil has, day and night, for our destruction.
O Lord Jesus Christ, the Model of our zeal for holiness, grant us a spark of Thy zeal that we may be like Thee in zeal, and be saved by Thee. To Thee be glory and praise forever. Amen.
