Looking for smart sermon podcasts

Someone asked me for sermons and sermon podcasts with smarter preachers, with more intellectually engaging content. This would be in contrast to the many other popular sermon podcasts that might be described as “putting cookies on the bottom shelf” and everyday language to try to reach the largest number of people, per se. Here’s what I found so far – please add a comment or contact me with others.

Holy Trinity – Todd Hunter (iTunes)

Vox Community – Mike Erre (iTunes | RSS)
