Waldron is a pastor/professor/missionary who comes from a Church of Christ background (the acapella guys). This is a good series, although I do have a couple of reservations. Here is an overview on each of the four lessons:
1) God’s Sovereignty and Total Depravity – Waldron explains the Calvinist concept of Sovereignty – that God “controls” everything, and how this is not a scriptural view. He addresses Total Depravity and refutes it from what I would call a Semi-Pelagian view.
2) Calvinism and TULIP – Waldron gives a little history on John Calvin, and then goes through the 5 points. He represents Calvinism very fairly and doesn’t create straw men. He is easy to understand.
3) Neo Calvinism #1 – Waldron argues that modern Calvinists have modified the system to make it seem not as harsh, and as a result are not as consistent as the old school Calvinists. He goes on a couple of tangents unique to the Church of Christ in this lesson (baptism, and complaints about instruments used in worship).
4) Neo Calvinism #2 – This lesson is on the differences between Imputed Righteousness (Calvinist view) and Imparted Righteousness (View of some Arminians). Waldron argues for the Imparted view, and makes some very good points. Imputed Righteousness advocates say salvation “covers” sin, where as Imparted Righteousness advocates say salvation “cleanses” sin.
