Let us sit at the feet of the great Confessor as he teaches on patriotism and war:

“Christian patriotism is, of course, alien to those extremes and errors into which "super-patriots" fall. A Christian patriot, while loving his nation, does not close his eyes to its inadequacies, but soberly looks at its properties and characteristics. He will never agree with those "patriots" who are inclined to elevate and justify everything native (even national vices and inadequacies). Such "patriots" do not realize that this is not patriotism at all, but puffed up national pride - that very sin against which Christianity struggles so strongly. No, a true patriot does not close his eyes to the sins and ills of his people; he sees them, grieves over them, struggles with them and repents before God and other peoples for himself and his nation. In addition, Christian patriotism is completely alien to hatred of other peoples. If I love my own people, then surely I must also love the Chinese, the Turks or any other people. Not to love them would be non-Christian. No, God grant them well-being and every success, for we are all people, children of one God.”

War in itself is absolutely evil, an extremely sad phenomenon and deeply contrary to the very essence of Christianity. Words cannot express how joyous it would be if people ceased to war with one another and peace reigned on earth. Sad reality speaks quite otherwise, however. Only some dreamers far removed from reality and some narrowly one-sided sectarians can pretend that war can be omitted from real life.”  

“It is quite correct to point out that war is a violation of the commandment, “Thou shalt not kill” (Ex. 20:15). No one will argue against that. Still, we see from the Holy Scriptures that in that very same Old Testament time when this commandment was given, the Israelite people fought on command from God, and defeated its enemies with God's help. Consequently, the meaning of the commandment, “Thou shalt not kill,” does not refer unconditionally to every act of removing a person's life. This commandment forbids killing for revenge, in anger, by personal decision or act of will. When our Saviour explained the deep meaning of this commandment, He pointed out that it forbids not only actual killing, but also unchristian, vain anger.”

“In a conversation with Mohammedans, about war, St. Cyril, the Enlightener of the Slavs, said, "We meekly endure personal offenses; but as a society, we defend each other, laying down our lives for our neighbors, so that you having taken them captive, do not force them to deny their faith or perform acts against God." Finally, what Russian does not know the example of St. Sergius of Radonezh, who blessed Prince Dimitry Donskoy to go to war, prayed for the success of the Russian army, and commemorated those soldiers who died on the field of battle?”

“One can, of course, sin and sin greatly while participating in war. This happens when one participates in war with a feeling of personal hatred, vengeance, or vainglory and with proud personal aims. On the contrary, the less he thinks about himself, and the more he is ready to lay down his life for others, the closer the Christian soldier approaches the martyr's crown.”
