Christians typically are familiar with the concept of spiritual warfare, but to a secular modern, the term might sound like gibberish. It is presumed false at best and nonsense at worst, because it probably refers to nothing.
The thinking goes like this. ‘Spiritual warfare’ refers to the devil or demons (fallen angels, purely intellectual beings who have disobeyed God, triggered by the sin of pride) acting to persuade humans to disconnect themselves from God. Yet, the devil or demons don’t exist. Therefore, spiritual warfare doesn’t exist.
The error here is in focusing on the theoretic instead of the practical. Since spiritual warfare is all about the practical, what ought to be of interest is how Christian strategies on this impact day-to-day life – does it help people to get better at or respond better to things? If so, there’s something important about the concept of spiritual warfare in the Christian tradition, even if the theory is ultimately in some way significantly mistaken.
To begin to show why ‘spiritual warfare’ is a relevant and interesting concept, even to a secular modern, I want here to map the term onto a term that modern seculars will understand. It is probably the best equivalent in the secular lexicon to ‘spiritual warfare’. To begin to understand it, we can think about psychological warfare.
Psychological warfare, from psyche (‘soul’ or ‘spirit’), is something most people can easily see is regularly occurring around them. For example, different countries have different interests, and will try to persuade people to take this or that position on some issue. Similarly with political parties, or companies.
The main tool with which these organizations fight is the media. Obviously, the extent and duration of media exposure is increasing. This means there is more potential for those organizations to engage in psychological warfare.
Many Christians believe there is unprecedented spiritual warfare occurring now. To see how this might map onto something important, consider that many Christians also believe that the main conduit of much of this is the media.
So, recognizing spiritual warfare or psychological warfare being conducted through the media is a point of contact for both Christians and critical-thinking secular moderns. It also opens a way for secular moderns to understand what Christians are talking about, without merely dismissing it as gibberish.
