Chrysostom's practical theology

For Chrysostom, solid doctrine add sound living remained an inseparable whole. What we know must deeply affect how we live. If not, the truth of the gospel is short-circuited and the watching world perceives a skewed picture of the gospel’s reality. Chrysostom views Paul, above all others, as the expert at fusing knowledge and life.—Christopher Hall, Reading Scripture with the Church Fathers, 96–97

A recurring theme in the church fathers. For them there was no salvation apart from a change in conduct. In other words, no cheap grace.

We could do with a good bit of that theology! Not works righteousness, mind you, but as I like to say: heart holiness.
