Heidelcast For September 7, 2025: Heidelcast: Nourish And Sustain (17): Theodore Beza’s A System Of Doctrine On The Sacramental Substance (1562)


Dr Clark continues the series on the Lord’s Supper, Nourish and Sustain. This series explores what the Supper is, why it was instituted, how it has been understood in the history of the church, what Scripture says, how we should understand it, and practice it.

The Lord’s Supper is one of the two sacraments instituted by our Lord Jesus Christ. A sacrament is a sign and seal of Holy Spirit-given benefits. Where baptism is the sign and seal of initiation into Christ-confessing covenant community, the Lord’s Supper is the sign and seal of renewal and personal appropriation of the benefits promised in the covenant of grace. Tragically, since the mid-ninth century at least, holy communion, which is intended to bring Christ’s people together, has often been a source of division. Perhaps worse, however, for much of the last one hundred fifty years, the Supper has been much neglected among evangelicals.

In this episode, Dr. Clark discusses Theodore Baza’s treatment on the substance of the Lord’s Supper.

  1. Just a humble protestant here. I come from a memorialist background but after a Deep look into oriental orthodox I came away sadly that memorialist has scant meat on its bones. I’m trying to keep it but I don’t find alot of support for it.
    I want to have that sacred wonder and joy in the Lords supper but I also want to be confident that how I partake is in faith believing.. Pray for this child here the journey is wearying…

    • Anthony,

      I recorded this series to try to show that there’s more to the Reformed view than mere memorialism. Please start at the beginning. I also recorded Calvin’s Short Treatise on the Lord’s Supper. It’s all on the Heidelcast page. Take a listen.

      The Reformed confess that, in the Supper, the Holy Spirit feeds believers on the “proper and natural body” and the “proper blood of Christ” (Belgic Confession art. 35). Yes, we remember but there is much more to the Supper.

      I don’t know what you mean by “humble Protestant.” The Reformed churches are Protestant churches.

      There’s no need to become Orthodox or Roman Catholic. The wonder of the Supper is the Holy Spirit operates mystically through faith to feed us on Christ’s body and blood in communion. What’s more wonderful or mysterious than that?
