Bring back the good old days, they are just around the bend.
The Christ did not let the church loose on the world with the idea of it being the world’s moral police.
It took that job description upon itself. To its dilution and diminution.
The gospel can lick any witch’s power with one hand tied behind its back. It can take anything polluted by sin and restore it to a holy context. It can shove Satan right back to hell. Trouble is, our weak modern Christians have settled for the nice society they got by being the world’s moral police.
God has arranged for this to fail, for excellent reason.
What time period are you talking about? If you are talking about the inqusitional periods of Europe, the psychopaths infesting the Church at the time were using that smoke screen to rid themselves of critics who threatened to expose the real evil doers running the church itself.
If you are talking about the Hebrews, there was danger that allowing witchcraft would corrupt and seduce the nation into sin, there bye inviting God’s wrath!
