Ever notice in the Scriptures how demons were cast out??....no "holy water" needed....they had something far, far more powerful. Perhaps Rome should take note.
Always amazing how Roman Catholics ignore the very book they claim to have given everyone.
17The seventy returned with joy, saying, “Lord, even the demons are subject to us in Your name.”Luke 10:17 NASB
16It happened that as we were going to the place of prayer, a slave-girl having a spirit of divination met us, who was bringing her masters much profit by fortune-telling. 17Following after Paul and us, she kept crying out, saying, “These men are bond-servants of the Most High God, who are proclaiming to you the way of salvation.” 18She continued doing this for many days. But Paul was greatly annoyed, and turned and said to the spirit, “I command you in the name of Jesus Christ to come out of her!” And it came out at that very moment.
Acts 16:16-18 NASB
31And He came down to Capernaum, a city of Galilee, and He was teaching them on the Sabbath; 32and they were amazed at His teaching, for His message was with authority. 33In the synagogue there was a man possessed by the spirit of an unclean demon, and he cried out with a loud voice,
34“Let us alone! What business do we have with each other, Jesus of Nazareth? Have You come to destroy us? I know who You are—the Holy One of God!”
35But Jesus rebuked him, saying, “Be quiet and come out of him!” And when the demon had thrown him down in the midst of the people, he came out of him without doing him any harm. 36And amazement came upon them all, and they began talking with one another saying, “What is this message? For with authority and power He commands the unclean spirits and they come out.” 37And the report about Him was spreading into every locality in the surrounding district. Luke 4:31-37 NASB
The demons recognize there is power in the name of the Lord.
Might be a good lesson for some to learn.
You know.. "In the Name of the Father, and of the Son, and of the Holy Spirit"?
You really ought to find out about stuff.
Might ask a Catholic?
Too much to expect?
