The Spiritual Science of Rennes-le-Château requires the result of turning the village into an eternal Tourist Attraction as a source of financial revenue. If you can do that, you can stop working for a living.

Personally, I regard the Churches of St Mary Magdalene and St Peter to be on the religious symbolical level. Mary Magdalene anointed the feet of Christ (the earthly) while St Peter was a fisherman (the spiritual) – but I have no idea if that was the intended symbolism.

Both elements reflect the importance of water, and Jesus Christ's early symbolism was the fish. Contemplating the spiritual significance of Lavender led me to this insight.
