How to explain why abortion is wrong

There are two approaches you can take. The first is to try to persuade people using moral principles which we all generally accept. The second is to appeal to revelation. Begin your discussion with the idea that no one has the right to take the life of an innocent person. Then discuss how the baby is a separate human being, distinct from his or her mother. Point out how each child has its own unique genetic identity, gender, heartbeat, brain waves, eyes, hands, feet, etc.

Challenge the person with whom you are speaking to consider whether society is actually moving backward or forward when it permits its young to be killed as a solution to its problems. Acknowledge that women do have certain rights over their bodies just as men do, but that these rights (of both men and women) are limited when they affect the rights of others. Abortion directly involves the rights of at least two people: the mother and the preborn child.

You should discuss what God has revealed about human life. Mention that the Bible teaches children are a gift from God and that God knows each child from his or her first moment in the womb (Jer. 1:5, Is. 41:2, 44:24, CCC 2270). Then ask, "Do you think God is pleased that His precious gifts are being brutally killed in the supposedly safest place on earth the mother's womb?"

If people tell you not to bring religion into it, mention that everything is ultimately a religious issue. God's law exists. You did not make it up. You are just telling them what the law is (Ex. 20:13).
