Is there a possibility that your holy images will get attacked by demons and what to do with Catholic teaching?

Yes, Catholic teaching acknowledges demons can influence things, even holy images or places, especially if associated with occult items or a lack of faith, but the Church provides powerful spiritual tools like sacraments (Eucharist, Confession), blessed items (holy water, crucifixes, medals), prayer (Rosary), and fasting to repel them, emphasizing God's greater power and urging reliance on Church sacraments and a holy life over fear. 

Possibility of Demonic Influence

• Attachment to Objects: Demons can attach to objects used in occult practices (Ouija boards, idols) or dedicated to evil, or even just present in a home without proper blessings.

• Targeting the Holy: Demons are particularly drawn to attacking holy things or people striving for holiness, as they try to corrupt or draw them away from God.

• Infestation/Oppression: This can manifest as disturbances in a place (infestation) or physical/mental harm to a person (oppression). 

What to Do (Catholic Teaching)

1. Live Sacramental Life: Regular Confession (Penance) and receiving the Eucharist are primary weapons against evil, as they confront sin and bring Christ's strength.

2. Use Sacramentals: Keep your home and objects blessed with holy water, use crucifixes, and wear medals to repel evil.

3. Pray Constantly: The Rosary, Scripture, and invoking the Holy Spirit are essential. Gregorian chant is also noted for its power against demons.

4. Seek Spiritual Guidance: Talk to a priest if you experience severe issues; they can offer prayers, blessings, or recommend the official Rite of Exorcism if needed.

5. Avoid the Occult: Stay away from activities like tarot, Ouija boards, or any practices that invite evil.

6. Live a Holy Life: Avoid sin, as it gives demons a foothold. Focus on virtues and turning to God for strength. 

Key Takeaway

Don't fear, but act with faith. God's power through the Church's sacraments and blessed items is infinitely greater than demonic power, and avoiding evil practices protects you.
