what impact has been made to the catholic church and the protestant churches… today?
The biggest impact that the Protestant reformation had was in commerce. Since the protesting countries stopped arguing religion, they become cognizant of the economy. England introduced banking, other countries introduced new economic concepts. Catholic countries stagnated. You can still see this effect in the economies of Catholic and Protestant countries. I am fuzzy on the concepts, but you can look it up. It was basically an economic reformation.
