In lecture 7, Dr. Trueman continues discussing Luther’s treatise On the Babylonian Captivity of the Church. The treatise reveals Luther’s comprehensive vision for the church. Within the treatise, Luther reduces the sacraments from seven down to three, and then in the conclusion, down to two. Luther is work in progress, having to rethink and build at the same time. Interestingly, Luther’s core thinking is systematic and consistent although he doesn’t write a systematic theology.
Dr. Trueman makes the point that examining heresy and errors in church history is instructive. Behind every heresy is a good question. In this vein, he discusses Luther’s problem with the mass and transubstantiation. He also covers baptism and penance.
The lecture also includes some interesting observations on present day counseling in relation to preaching.
