Reformed Theological Seminary Lectures

There are many freely available lectures and courses on various religious and philosophical topics at Reformed Theological Seminary. All one needs to do is connect to their iTunes webpage and download the iTunes app (if you don't have it already). Currently, the link is here: http://itunes.rts.edu/

The link may be changed in the future. In which case, you can eventually find the link at the seminary's main website (usually under Resources). http://www.rts.edu/

They have many courses on topics like apologetics, theology, church history, history of philosophy et cetera.
