Tonus-it is a range of practices, can those be identified? This is important if the description is accurate and true, since it means that there is an organization/religion (or many of them) that is working in direct opposition to God himself and which God advises his followers to flee from. Without knowing who it is, how many might be following the wrong religion and dooming themselves to an eternity of suffering?
These are important questions for a Christian for sure. This is why I don't think the practices I mentioned regarding demon worship and witchcraft are a small thing. And they would clearly point to the spirituality that us in direct opposition to Christianity.
I mentioned earlier the work of Augustine, City of God, in which he condemned these practices extensively..meaning he spent a great part of the book referring to these practices (overt and those not so overt) in comparison to the correct way of worshipping God.
Augustine went to the 'core' of the matter..the fact that it's a spiritual battle first and foremost. Any religion practicing sorcery and witchcraft would clearly be in the camp of Babylon the great.
