Should a Christian join the military?

TL;DR:

. Joining the military is a personal decision. Above all, whether joining the military or not, honoring God in every choice is what matters most.

from the old testament

  • Exodus 15:3 acknowledges that God, in His sovereignty, has a role in war. The concept of military action is not inherently against God's nature.
  • The census in Numbers 1 was of those “from twenty years old and upward, all in Israel who are able to go to war” (Numbers 1:3).
  • God instructs the Israelites on how to approach war (Deuteronomy 20:1–4), with the assurance that God is with them, indicating military engagement in certain circumstances.
  • Deuteronomy 24:5 says, “When a man is newly married, he shall not go out with the army or be liable for any other public duty. He shall be free at home one year to be happy with his wife whom he has taken.”
  • In 1 Samuel 8:20 the people of Israel request a king to lead them in battle, which shows the reality of military service for protection and defense.
  • Psalm 144:1 says, "Blessed be the LORD, my rock, who trains my hands for war, and my fingers for battle." This verse reflects the idea that God sometimes equips people for warfare, indicating that military action is a valid means of serving in God’s plan.

from the new testament

  • Matthew 5:9 highlights the importance of peace, suggesting that Christians should pursue peace whenever possible, though it does not explicitly rule out military service.
  • John the Baptist instructs soldiers on how to live righteously within their role (Luke 3:14), indicating that military service itself is not condemned, but the manner in which one serves is crucial.
  • Romans 13:1–4 affirms the legitimacy of government authorities, which would include those who serve in the military, as agents of justice, carrying out God’s will to protect and maintain order.
  • The metaphorical reference to military service in 2 Timothy 2:3–4 illustrates the discipline and focus required to follow Christ, but that it was used as an example implies that serving in the military can align with Christian virtues.

implications for today

Military service is required in many nations. Participating would thus fall under the guidelines of Romans 13:1–7 and Acts 5:29. Depending on the circumstances, a believer might also prayerfully request an exemption from service. In nations where military service is voluntary there are several considerations for believers when it comes to whether to join.

Can you in good conscience swear to and abide by the enlistment/commissioning oath?

A good military oath will demand loyalty to the nation and possibly the law and/or constitution of the nation. A bad oath will pledge allegiance to a specific leader. The German oath includes promises to serve the country and defend the law and the freedom of the German people. The Polish army pledges to serve and defend the country, guard the constitution, and preserve the honor of both the soldier and the military forces. The U.S. enlisted oath does not mention defending the nation, but does pledge to defend the constitution and obey the lawful orders of the president and officers in command. The officer oath is similar, but vows to serve well and faithfully, instead of following orders. Although Jesus admonishes us to be of such character that oaths are not necessary, military branches often require them for service. If you can't make such an oath willingly and with the full intent to keep it, military service probably isn't a good idea.

Are you willing to support the geopolitical leanings of the nation with your life?

The authorities of a nation have the God-given right to defend their nation. Soldiers under that authority are in their rights to kill—as long as they do so legally (generally, according to the Geneva Convention). This, for the most part, morally absolves soldiers of guilt in regards to legitimate wartime violence. But before the fight begins, before the person even joins the service, he needs to be able to say, "Yes, I trust that, in any situation my country puts me, I can follow orders with no great hesitation." A little hesitation is normal—any job is going to have odious tasks. And allegiance to a nation does not mean absolute understanding and support of every order. A believer should reconsider before swearing to fight for an abusive and corrupt regime or one that sends him into a war he absolutely disapproves of.

Can I be, or do I have a problem with being, a person who has killed another?

For many, this question doesn't even come up until after the deed is done, but it's a good idea to think about it beforehand. Most militaries have non-combatant roles such as chaplains, medical personnel, and many other career fields that may never directly engage the enemy. But the military is still in the business of death, and every support job, eventually, works in support of a weapon. In addition, the needs of the military will outweigh any promised job position. For example, if no combat officers are free to provide armed escort for a supply caravan, a logistical officer may very well be called up instead. (See Judges 4:17–22.)

Is the military life something I and my family can accept?

In the U.S., there are many advantages to having a family in the military. They will get to travel to different places, meet new people, and usually not have to worry about income. But every family needs to decide if the benefits are great enough to outweigh the disadvantages. Travel to visit extended family is expensive. The military member will often not have a choice of assignments. Spouses and children may not want to move or may be fearful of every new deployment. A commitment is a commitment. A five-year commitment doesn't change if you meet and marry the love of your life within the first two years. You still have three years to serve, and much of that may be deployed.

What is my motivation for joining the military?

In the U.S. the military can often provide regular income, advanced education, and medical care. It is not uncommon for a poor high school student or someone with an ill spouse or child to see the military as an answer to his needs. And it is not necessarily bad to consider the military for these reasons. But the other questions should still be considered. Is health care or a college degree worth spending eighteen months in a foreign country being shot at? Is it worth spending eighteen months shooting back? Is it even possible to work toward a degree while being deployed every other year? For many, the benefits are worth the risk and inconvenience, and military retirement may one day free a family for other opportunities. But it's a question that each individual and family should answer for themselves.

What about mandatory military service?

In some countries military service isn't an option; it's mandatory. In that case, to serve is to obey the civil authorities God has placed in power. If, however, a Christian is conscripted into the military of an evil regime, he should make every effort to find a noncombatant role or determine if there is a legitimate cause for civil disobedience. Also, he should pray for wisdom and trust that God can glorify Himself in any situation.

A Christian considering the military should prayerfully process these questions and then follow the Holy Spirit's leading (James 1:5). Strong, Spirit-filled believers are needed in the military, just like they are needed in every other field of endeavor. Military service is an honorable option, but, in most cases, it's only one option.

understand

  • The Bible does not directly answer the question of whether Christians should join the military of their nations today, but it does recognize the existence of war and the role of soldiers in both the Old and New Testaments.
  • Christians are called to pursue peace, serve under government authorities, and engage in roles that promote justice and protect the vulnerable
  • A Christian can join the military if done with a sense of righteousness, and faithfulness to God’s calling.

reflect

  • How do you understand the idea of serving in the military? How does your personal faith influence your thoughts on military service?
  • If you are considering joining the military, how do you reconcile the call to pursue peace with the potential of engaging in war or violence?
  • What role do you think your faith should play when making major life decisions like joining the military?

engage

  • Some people worry about joining the military because it might involve killing. However, although the King James Version says, "Thou shalt not kill" as the Sixth Commandment, the better translation is "Thou shalt not murder." This is different than wartime situations. Others worry about joining the military because they categorically condemn war and the military. However, such a position is personal perspective not explicitly biblical.
  • How can a Christian maintain integrity and righteousness in a military role, especially in the face of difficult moral decisions?
  • What are some of the challenges that Christians in the military might face? How can the church support those in the military in living out their faith while serving?
