The main difference between Bronsted and Arrhenius acids and bases is that Arrhenius' definition is specific to aqueous solvents (aka water). He defined an acid as a compound that contains hydrogen and reacts with water to form hydrogen ions and a base as a compound that produces hydroxide ions in water. When considering nonaqueous solvents, Bronsted developed the following definitions: an acid is a proton donor, and a base is a proton acceptor. I hope this answers your question. Section J1 in the textbook goes into more detail about the two, and I found it really helpful.
