I've been thinking about the Trinity all year. Studying at Ridley has shaped my theology, mostly I think for the best and no where more so then with the doctrine of the Trinity. I clearly remember floundering in my understanding of it last year. However Peter Adam's classes, Andrew Moody's guest lectures, The Trinity by Olson and Hall and The Doctrine of God by Gerald Bray has given me a large dose of clarity. To cap it all off these two lectures, I listened to recently, by J.I. Packer sum up the doctrine of the Trinity very clearly. (I am still in awe of the doctrine and it'll take some time for me to digest what I've learned.)
JI Packer's first lecture and his second.
