Darwin Catholic has a very good article on Pastor of Souls/Pastor of Soldiers on his blog. Additionally as a day to remember those who have died for their country please consider sending an e-mail to the troops.
If you don’t know a deployed veteran, ask your friends if they do. You can also ask your church, or the local VFW or American Legion post for information on veterans from your community who are serving.
IF you feel the Christmas spirit for a soldier.
Saint Augustine (to the soldier Boniface) letter 189,4
4. Do not think that it is impossible for any one to please God while engaged in active military service. Among such persons was the holy David, to whom God gave so great a testimony; among them also were many righteous men of that time; among them was also that centurion who said to the Lord: “I am not worthy that You should come under my roof, but speak the word only, and my servant shall be healed: for I am a man under authority, having soldiers under me: and I say to this man, Go, and he goes; and to another, Come, and he comes; and to my servant, Do this, and he does it;” and concerning whom the Lord said: “Verily, I say unto you, I have not found so great faith, no, not in Israel.” Matthew 8:8-10 Among them was that Cornelius to whom an angel said: “Cornelius, your alms are accepted, and your prayers are heard,” Acts 10:4 when he directed him to send to the blessed Apostle Peter, and to hear from him what he ought to do, to which apostle he sent a devout soldier, requesting him to come to him. Among them were also the soldiers who, when they had come to be baptized by John,—the sacred forerunner of the Lord, and the friend of the Bridegroom, of whom the Lord says: “Among them that are born of women there has not arisen a greater than John the Baptist,” Matthew 11:11 —and had inquired of him what they should do, received the answer, “Do violence to no man, neither accuse any falsely; and be content with your wages.” Luke 3:14 Certainly he did not prohibit them to serve as soldiers when he commanded them to be content with their pay for the service.
