Gospel magic as I see it is this:
It is standard magic tricks (cards, coins, stage, close-up, escapology, etc.) which is done in a Church setting. I think that it has three facets (at the moment, I'm working on this as a project so this is a work in development).
1. Magic, done by Christians, where the content may have no connection to anything Biblical. This is purely Christians doing magic.
2. Magic which might have a link, often it seems tenuous but a link, that is done as part of street magic, church services, evangelistic work, etc.
3. Magic where the trick is subordinate to the actual message and the point that it is being used to illustrate.
This day will help people to develop basic skills, use magic in services and other Christian events as well as assemblies and the like. It will be followed up in September by what I'm hoping will be a week of magic - taking stuff into schools, novice, intermediate and master-classes and will culminate in a show at the local theatre (don't know who yet - looking for someone.)
The late Pete McCahon was president of the the fellowship of Christian Magicians (

Hope this helps,
