Catholic Public Domain Version
Deuteronomy 20:18
“Otherwise, they may teach you to do all the abominations which they have committed for their own gods. And then you would sin against the Lord your God.”
Verse Explanation
A saved explanation for Deuteronomy 20:18.
Plain-language explanation
Moses warns Israel against adopting the religious practices of the nations they are to displace. The danger is not only their own actions, but being influenced by what those nations taught—so that Israel would end up repeating those “abominations” and, as a result, sin against the Lord.
Catholic context
Many Catholics read this as a call to protect the heart from cultural or “religious” influences that lead away from God. The verse emphasizes that spiritual compromise isn’t neutral: choosing teachings and practices contrary to the Lord can draw one into sin.
Historical background
In Deuteronomy’s setting, Israel is living on the edge of the Promised Land. Surrounded by peoples with different gods and practices, Israel is warned that those practices often came with instruction and persuasion. Moses’ message is that religious compromise could spread through teaching and imitation.
Reflection
A key warning here is about influence: someone may try to get you to do what they themselves have done. What teachings are we letting shape our beliefs and habits? If a “practice” leads away from the Lord, it may start with small steps and become real sin.
Practical takeaway
Be attentive to what you’re absorbing—friends, media, community norms, and ideas. Choose formation sources that lead you toward the Lord (Scripture, the Church’s teaching, prayer), and gently refuse what pulls you toward practices or beliefs that contradict God’s ways.
Prayer
Lord, keep my heart faithful. Help me recognize any teaching or influence that leads me away from You. Give me courage to refuse what is contrary to Your will and grace to grow in holiness. Through Christ our Lord. Amen.
