Here is my homily actually for the vigil of All Saints day October 31. Values of the Kingdom of the Saints versus demonic anti-values, All Saints feast.
I am seeing more and more people come to me and the other priests here for deliverance prayers from demonic attacks after involvement with the occult or open wounds such as unforgiveness and mortal sin. So, my references to the demonic are from personal experience. However, my experience also shows the power of Christ is so much greater than any demonic activity.
