The painter loves extremely saturated paints/colors they also like perfect positioning and posture the mood of this gives me a bright feeling and old paintings with a lot detailing and saturation’s
Not sure if this is what you need.... but....it is the teaching of the Catholic Church that in the Eucharist the appearance is quite unchanged, but the basic reality has become the body and blood of Christ.
The change from bread and wine to a presence of Christ that is true, real, and substantial is called transubstantiation.
