The answer would be Catholic Arts are mostly base their arts in the bible and about their religion while the Protestant art rejected mostly of the arts from catholic arts and create a simpler and new way of arts. They depict it because they want to be different from the catholic and its also because of the reformation.
This artwork is using textures by using the jam and peanut butter, i think it is also using negative space, there are different tones and colours, like the jam is a warm red and the peanut butter is a cold light brown, i also feel like the lines aren’t definite but rather different on both sides.
