"The demons believe in one God also. And tremble."
...But the demons do not have faith in Him and they do not love Him. Such "believe-ism" is not faith, which is a living faith because it is a living faithfully. Have some kind of verbal, notional, non-faithful "faith" but without love, and you are nothing, says St. Paul.
May love capture our hearts more and more, R2Z. Tagline.
Through catholic belief that they eat the real body, blood, soul and divinity of The Christ at Mass in the wafer held up by the Priest, the demons continue the victim sacrifice in their hearts at every catholic Mass, mocking the Once For All Forever Supreme sacrifice done on the Cross once by The Great High Priest, Jesus the Christ, who is seated at the Right Hand of The Father waiting until His enemies be made His footstool. He is not being brought down from Heaven at every Mass, to continue the victim sacrifice the catholic church teaches. But the demons attend these Masses, grinning in their evil hearts at the shear blasphemy they are witnessing.
