For a while now UCCF (the UK Universities and Colleges Christian Fellowship) has been developing its Theology Network, which purports to

…equip you with top quality theological resources- both articles and audio talks. We believe that Christian theology is the most exciting thing possible since it’s simply about knowing God better.

And they do an excellent job. Don't let the fact that you're not a student stop you from mining the great resources available here.

Their latest offering is “Foundations“, a ten week course for individuals or groups. I'd struggle to find a better basic overview of Christian doctrine than what is offered here. And it's all free!

Theology Network is headed up by Dr. Mike Reeves who I knew in London. He's an astounding guy and, not least, a phenomenal teacher of God's word in all its aspects.

Hie thee hence to Foundations.
