This paper aims: 1. To discuss Romano Guardini’s method of philosophical and religious studies and its achievements, i.e. presenting the Christian eidos as finding its fullest expression in Jesus as our Lord. 2. To compare Guardini’s method with medieval philosophy as taught by Thomas Aquinas and others. Citing G. van Rieta, the paper attempts to show that Thomism should be continued today, drawing on contemporary philosophy, the phenomenological method in particular. This is a reliable way to see what Christianity is in itself, in its specific religious character.
