The general term that early Christian thinkers used to describe their intellectual work was, more often than not, simply “philosophy” or “Christian philosophy”. Christianity was regarded as the “true philosophy” over against the false philosophical schools associated with pagan thought. (See Justin Martyr, Dialogue with Trypho 8.1; Clement of Alexandria, Stromata 1.28.3, 1.28.4 1.80.5,6; Augustine of Hippo, Against Julian, 4.14.72.) This usage is consistent with Pierre Hadot’s (1995) claim that in Greco-Roman antiquity philosophy was understood as a comprehensive way of life. Christianity, on this model, is analogous to a philosophical school, in Hadot’s sense (see also Zachhuber 2020).
