Christian Denominations: How They Differ on Killing in Self-Defense
Catholic Church
The Catechism (2264-2265) explicitly permits legitimate defense of oneself and others. The act of self-defense can be morally good as it aims to preserve life. Excessive force, however, would be sinful.
Catechism of the Catholic Church
Protestant Churches
Most Protestant traditions accept self-defense as morally legitimate, citing biblical examples and the God-given right to protect life. Pacifist traditions (Quakers, Mennonites) reject violence in all circumstances.
Holy Bible (Protestant canon)
Eastern Orthodox
The Orthodox Church acknowledges the tragic necessity of self-defense in a fallen world. While all killing is a tragedy, defending innocent life is not treated as murder. It should be followed by pastoral counseling and prayer.

Christianity has a nuanced but generally permissive stance on self-defense. The Catholic Church explicitly teaches in the Catechism (2264) that legitimate defense is not only a right but can be a duty, especially when defending others. The key principle is proportionality — using no more force than necessary. Augustine and Thomas Aquinas developed Just War Theory, which applies similar principles to national defense. Protestant views vary: most accept self-defense as biblically grounded (Exodus 22:2, Luke 22:36), while pacifist traditions like Quakers and Mennonites reject all violence. The Orthodox Church acknowledges the tragic necessity of self-defense in a fallen world while mourning any loss of life.

Is killing in self-defense considered murder?
No.
No. In all three Abrahamic traditions, killing in legitimate self-defense is distinguished from murder. Murder is the unjustified taking of innocent life. Self-defense protects innocent life from unjust aggression. The intent matters: self-preservation vs. malice.
What about 'turn the other cheek' (Matthew 5:39)?
Scholars debate this passage.
Scholars debate this passage. Many interpret Jesus as teaching about personal insult and revenge, not about life-threatening violence. The Catholic Church and most Protestant traditions distinguish between turning the other cheek to personal slights and the duty to protect innocent life from lethal threats.
How much force is allowed in self-defense?
All three traditions emphasize proportionality.
All three traditions emphasize proportionality. You may use the minimum force necessary to neutralize the threat. Excessive force — continuing to attack after the threat is neutralized — would be sinful. The goal is to stop the threat, not to punish.
What if I could have fled instead of fighting?
Christianity generally encourages retreat if safely possible.
Christianity generally encourages retreat if safely possible. However, none require retreat if it would leave others in danger.
