It seems you're asking for a review of the phrase (the Lord’s Prayer / Magnificat said backwards).
According to legends (often told in Mexico and Central America), reciting the Magnífica backwards at midnight while holding a reversed black candle is said to: Make a person invisible to their enemies.
