Notes on Reformed Theology

Short essays on the doctrine behind the history — the arguments, not just the events.

  1. The Five Solas, Plainly Stated

    Scripture alone, faith alone, grace alone, Christ alone, God's glory alone — what each phrase was actually arguing against.

  2. Zwingli and Calvin on the Lord's Supper

    Neither man agreed with Luther's real presence, but they didn't fully agree with each other either — a difference that shaped two branches of the Reformed tradition.

  3. Predestination Before Calvin Made It Famous

    The doctrine didn't start with the Institutes — tracing it back through Augustine and into Zürich's own early preaching.

  4. Covenant Theology and the Heidelberg Catechism

    How the Palatinate's catechism organized doctrine around comfort rather than system — and why that mattered.
