In the parable of the Good Samaritan there is a direct relationship between audition (faith), decision (mercy) and recitation (hope). The story narrated by Jesus Christ is dialectically founded upon these three pillars which define, on one side, a plesiologic aretology and, on the other, suggests a form of poetic ethics, that has its foundation on a deliberative compassion, as it is elaborated on the basis of the exgetical commentary on the parable of the Homo Viator.
