In this second part of her interview with American Jesuit theologian Bart Geger, Pat Coyle explores with him the 'discernment of spirits'. St Ignatius talks of the good spirit and the bad spirit, and learning to recognise which is which. Bart Geger explains what Ignatius has to say on the topic, along with the much earlier Church Fathers. He also relates this discernment process with coming to know God's will.
