“The” good is a specific set of transcendent norms/commands/ways which objectively constitute “that which is right”. Referring to “the good” is less ambiguous than “being good” or “doing good”. The phrase is utilized intentionally insofar as the reference is to virtue, virtue being a conscious and firm choice to do “the good”/what is right. (As opposed to being a sort of “general state of rightness”.)
Does that make sense?
