It's witchcraft.
Always turning of things upside down.
It was the real witches that instituted the witch trials accusing well-meaning Christians of witchcraft resulting in many innocents being put to death.
It's always the heretical witches that call God's True believers heretics.
Yes.
And Paul says, that if you have lost your faith.........real faith in Christ to keep you saved......... In other words......you are not completely trusting any longer that Christ ALONE is your Salvation, and that not of yourself.....then Paul said you were led to this deception.
He teaches that if that is you, ...if you now believe you can "lose your salvation"< then your faith is subverted, and you are : "BEWITCHED".
