"You have heard that the ancients were told, 'YOU SHALL NOT COMMIT MURDER' and 'Whoever commits murder shall be liable to the court.'
       But I say to you that everyone who is angry with his brother shall be guilty before the court;
       And whoever shall say to his brother 'Raca,' shall be guilty before the Supreme Court; and whoever shall say, 'You fool,' shall be guilty enough to go into the fiery hell.
       If therefore you are presenting your offering at the altar, and there remember that your brother has something against you, leave your offering before the altar, and go your way; first be reconciled to your brother, and then come and present your offering."
       "Make friends quickly with your opponent at law while you are with him on the way, in order that your opponent may not deliver you to the judge, and the judge to the officer, and you be thrown into prison.
       Truly I say to you, you shall not come out of there, until you have paid up the last cent."(Matthew 5: 21 –26)

  The first law of the laws of the kingdom of heaven can be divided into three sections:

1.  we don't have to be angry with our brother (Matthew 5: 21,22)
2.  we have to forgive our brother according to the way that the book told us about (Matthew 5: 23,24)
3.  we don't have to let our brother to have something against us (Matthew 5: 25,26)

      Not To Be Angry With Our Brother
      God forbade the Jew "don't kill" under ancient Moses' low. That means that shedding blood was forbidden for him.
      But Jesus went far beyond this where He reached the origin of killing, that is the concealed anger in the heart, and forbade it by His law. Keeping anger inside the heart transfers to hatred. Cain was angry and so he envied, that means that he killed love and then killed his brother.
      Saint Jerome said "I don't know peace without love, or companionship without peace"
      Saint Paul said "It is my desire, therefore, that everywhere prayers be said by the men of the congregation, who shall lift up their hands with a pure intention, excluding angry or quarrelsome thoughts"
  -There are three degrees for anger:
      To bear anger towards our brother. And here the judge studies the accusation to make sure it's rightful.
      To despise our brother (as the word raca is an expression of despise and disrespect towards the one whom the talk is directed towards him). And here the Supreme Court studies the accusation for it is the highest legitimate court where its judgements can't be reluctated.
      To bear in heart hostility against our brother (you fool is an expression void of blessing as it may make him desperate, and the desperate person doesn't see heaven's door) and if we reach that extent it becomes doubtful that we are God's sons and we shall be guilty enough to go into the fiery hell. The fiery hell is the word gohanem in Arabic (gohanem: consists of two ibreian words "go-hanom" which means inside hanom, and hanom is a valley where the residues of the animals are thrown and the butchering full of worms and the fire is burn in it without separation, as a sign for devil's punishment and his soldiers – its worms don't die and its fire doesn't put out).
       And if we reach the third degree we find it equal to murder in the Old Testament. As if we keep anger inside our heats, it transfers to hatred. So how can we hate to see a person, while God has created him as us on His shape and example? For this apostle John assures what is mentioned in the sermon on the mount by saying: "we know that we have passed out of death into life, because we love the brethren. He who doesn't love abides in death.
       Everyone who hates his brother is a murderer; and you know that no murderer has eternal life abiding in him." (1 John 4: 3,4)
       So who has anger against his brother doesn't inherit the heaven that God prepared for His sons those whom He gave them to love one another.
       We might not bear hostility against our brother but does we despise our brother by one mean or another? Does we treat him with scorn? Who are we to scorn others. Dawood said about himself "I am a dead dog" and without God we are nothing. So we mustn't interfere in others' affairs.
       I am afraid that sometimes we despise our brother and break the first law of the laws of heaven.
       Someone may say: you forgot an important sentence: didn't the book say who is angry with his brother falsely? !! When I become angry with my brother, I don't become angry with him falsely
       Oh I have also hidden behind this excuse many times. In many times I had anger upon my brother, and in every time I said to myself that I have a notable excuse for my anger, but this is not the translation of the statement in the Greece language.

The Wrong Anger
        We deceive ourselves and justify the hatred that we bear in our hearts, but no one can judge whether the anger is false or not except God. And may be the motive for anger itself is a sin and examples of this include:
         Anger according to envy: as the Jews angered against Jesus when they heard the children crying "Hosanna to the Son of David" they became indignant, and said to Him, "Do You hear what these are saying?" (Matthew 21:15). The voices of the children angered them, while the noise of the vendors in God's sanctuary didn't anger them.
         The elder son: became angry, and was not willing to go in (Luke 15) to celebrate his brother's return.
         Esau and Jacob: a competition in which the competitor succeeded twice as Jacob run after Esau twice in the benediction and the blessing.
          The Jews: when they didn't bear that Jesus bemoan them on their sins "all those in the synagogue became angry when they heard this" (John 24:15-28)
          Saint Paul said, "Have done with spite and passion, all angry shouting and cursing, and bad feeling of every kind. Be generous to one another, tender hearted, forgiving one another. (Ephesians 4:31,32). All this is an anger that doesn't make God's righteousness because it is against all virtues.

The Holy Anger
           I suppose that I hear someone saying (Doesn't the bible tell us in "Ephesians 4:26" to bear anger?
           Yes there is anger that is among God's attributes. And we as sons share it as the statement is obvious and not subject for any interpretation and it doesn't mean to bear anger upon our brother as it says "If you are angry, do not let anger lead you into sins; do not let sunset find you still nursing it; leave no loop-hole for the devil." (Ephesians 4:26) and this statement is to be considered as an exercise for us.
           The motive to the holy anger is pure jealous on God's name, His holiness, and His wills and a true intention to defend the right without any personal motive. And it is to defend God's indignity and not our own indignity and examples of this include:
           Moses: whom no one was like him in his patience and meekness, when he saw the golden calf that the Israelites made he became extremely angry (Exodus 32:19,20).
           Nehemiah: when he found the Jews – during building the rampart loaning their brothers with usury and humiliate them and when he heard the scream of the populace with his ears he became angry and blamed the nobles and the rulers on the usury and refrained them from it and let them have mercy on the populace (Neh. 5).
           Saint Paul: was exasperated to see how the city was full of idols. (Acts 17:16)
           Jesus: when the Jews watched Him while He was healing the man with the withered hand in the Sabbath "And after looking around at them with anger, grieved at their hardness of heart" (Mark 3:5)
          Jesus in the temple: He found inside it the sellers and the moneychangers "overturned the tables of the moneychangers and the seats of those who were selling doves and He began to teach and say to them, "Is it not written, 'MY HOUSE SHALL BE CALLED A HOUSE OF PRAYER FOR ALL THE NATIONS'? But you have made it a ROBBERS' DEN." (Mark 11)

          The statement that Paul mentioned that is not subject for interpretation: "do not let sunset find you still nursing your anger" means don't sleep while you bear in your heart hatred towards the other person. And this is an exercise for every husband and wife, as the situations have to be solved immediately, every one of them should ask the other if there is anything that he (she) did that disgraced her (him) so that they can go to sleep in serene and peace and so that God's peace flickers around them "The sun will not smite you by day, nor the moon by night".
           Sometimes in the reconciliation sessions in which we mediate we hear the wife saying to her husband "I have been angry of you since twenty years" twenty years bearing in her heart!! And the husband saying to his wife "I have been bearing your acts since thirty years" How can these happen?! if they solve each dispute immediately, hatred would not have been accumulated in heart, which often causes the chronic diseases.
           Let us leave pride aside and each one of us asks the other for forgiveness so that peace and love perpetuate in our houses.
           We read about the conditions for love "love is not provoked" (1 Corinthians 13:5) With love there is no place for anger and there is no place for intolerance for every person mistakes even if his life is only one day on earth.
           Do you provoke on your wife, or on your children, or on your brother, or on anyone of your house, or on your employees, or on your boss!
           Let me tell you that this issue is a restraint for blessing.
           How many people became angry for a dispute on a small fortune or for their feeling of humiliation. Which is better to bear humiliation and gain heaven or become angry and go to the fiery hell. When you bear humiliation, God bears you.
          How many people nowadays are angry with others! How many disputes are there among Christians themselves
          I may disagree with some people on a certain action. May be some people disgrace you so that you don't talk to them: so if you happened to meet them in the street you turn to a lane, or turn your sight to another direction as if you don't see him, and if you happened to meet them face to face you stare at them with an abstracted look that expresses what is in your heart of repugnance and may be antagonism and then you complain and ask why you didn't obtain the blessing, or become full of the Holy Spirit!
          How many families' disputes in which no one blames himself and says it is because of me. When a severe hurricane happened in the sea, Jonah said it is because of me. So, God prepared that a whale swallows him, and the whale became a room for prayer. And Jonah prayed until God returned him to the place in which he disobeyed Him and where the reconciliation took place.
          Don't you dare sleep while you bear in your heart hatred against anybody and then hold yourself inculpable and say I love him but with a distant between us. Love means approach but love at distant leads to God saying to you: I don't know you, stay away from Me.

Question
           Do you know the hidden motive that leads you to be angry on or provoke your brother?! It is not the newly born human being: as this one is created in holiness and godliness. And as saint John says in (1 John 3:9) no one who is born of God practices sin, that means that he doesn't continue with his sins but repents and confess his sins.
          Then this motive is with no doubt originated from the ancient human being, that is the ancient erroneous life that is still sticking to you and me, and which you got rid of by baptism: by the new birth from water and soul, and from which you are renewed by repenting and confessing before God in the presence of the priest.
