First Things is published by The Institute on Religion and Public Life, an interreligious, nonpartisan research and education institute whose purpose is to advance a religiously informed public philosophy for the ordering of society.
The First Things podcast is incredibly enjoyable. A great mix of ecclesiastical stuff, theology, and high and popular culture. Stimulating, thought-provoking conversation with lots of dry humour. I don't always agree with what's said but that's definitely part of the fun. I recommend.
