For pastors who want a refresher or another perspective, and for lay leaders in the church who can not head off to seminary, a great resource on the Internet is Reformed Theological Seminary’s virtual campus. RTS provides lectures to full courses at a Master’s level that are available free on iTunes. You can find the information here. There is even a way that you can earn an accredited Master’s through distance education in this manner. I am not the most reformed Christian, but I have enjoyed listening to these lectures (I have listened to the courses on Apologetics and Pentateuch) and I have learned lots. This is a great resource that should be taken advantage of.
