In her influential monograph Roman Faith and Christian Faith: Pistis and Fides in the Early Roman Empire and Early Churches, Theresa Morgan has convincingly shown how closely the early Christian discourse on ‘faith’ was bound up with similar notions in the broader Greco-Roman world, particularly in relation to the system of patronage, with both humans and deities fulfilling the role of (trustworthy and trusted) patrons. Thus, she has shifted attention from πίστις/fides as a primarily ‘theological’ notion to an interpretation along more ‘social’ lines and situated it in realm of human and divine/human relations. She also analyses this in relation to the Gospel of Mark, showing how Mark also fits this general picture. This note builds on Morgan’s work and will further develop one aspect of Mark’s use of the language (and concept) of patronage and πίστις. This is its subversive character, which is present to a lesser extent in Morgan's work; by calling for πίστις directed to him on the part of the people that he encounters, Jesus also draws these people away from other allegiances and ‘πίστις commitments’, that is, intersubjective relationships based on trust and leading to personal allegiance.
