Dear Brother I want to thank you. Here, where I live, it is not easy to get Reformed teaching but thanks to technology I have been able to listen to the Heidelcast; specifically to the series on the Marrow of Modern Divinity. . . . Continue reading →

Heidelcast Series: God’s Holy Law
The historic, confessional, Reformed understanding of Scripture is that it contains two kinds of words, law and gospel. The law promised eternal life to Adam on condition of perfect obedience on behalf of all humanity. Adam sinned, transgressed God’s holy law, and . . . Continue reading →
Heidelcast Series: Nomism And Antinomianism
Almost since the beginning of the Reformation there were two reactions to the recovery of the gospel: legalism, or nomism, and antinomianism. There are associated doctrines and practices but the core of antinomianism is the rejection of the abiding validity of the . . . Continue reading →
Heidelcast Series: I Will Be A God To You And To Your Children
The question of baptism, who should be baptized and why, is not just a question about the sacraments. It is a question that is integrally connected to the way we read the Scriptures (hermeneutics), the way we understand redemptive history, the way . . . Continue reading →
Heidelcast 130: I Am That I Am (8)—Against Social Trinitarianism
In the last few episodes we have been considering the biblical, ecumenical (or creedal) doctrine of the Trinity. The God who is, is one in three persons. The historic doctrine of the Trinity is very clear. It is also great mystery but . . . Continue reading →
Heidelcast 129: I Am That I Am (7)—The Trinity In The New Testament
Augustine of Hippo used to say that what was concealed in the Old Testament is revealed in the New Testament and that is certainly true in case of the biblical doctrine of the Trinity. As we have discussed so far in the . . . Continue reading →
Heidelcast 128: I Am That I Am (6)—The Trinity And The Covenant Of Redemption
I am excited to back behind the Heidelmic again and judging from the discussions I am seeing in print and online it looks like it is none too soon. James Dolezal has published an important new book, All That Is In God: . . . Continue reading →
Heidelcast 127: I Am That I Am (5)—The Trinity
There strong indications in the Hebrew Scriptures that the God of the Bible is not only personal, but that he is multi-personal. In Genesis 1:1, Scripture says that Elohim (God) created the heavens and the earth. In the very next verse, however, . . . Continue reading →
Heidelcast 126: I Am That I Am (4)—The Trinity
Traditionally, at this place in theology, we should address the divine attributes in relation to the divine being/essence. Otto Weber (1902–66) challenged this approach by arguing that because Scripture reveals God first of all as Triune and his attributes in the light . . . Continue reading →
Heidelcast 125: I Am That I Am (3)—More On The Categorical Distinction
So far in this series we have been talking about what I call the categorical distinction, i.e., the Creator/creature distinction. At the 1518 Heidelberg Disputation Martin Luther unveiled what he called his theology of the cross, (theologia crucis) against what he described . . . Continue reading →
Heidelcast 124: I Am That I Am (2)—The Categorical Distinction
The Creator/creature distinction is fundamental to Christian theology. The Ancient Christian church defended it against the pagan doctrine of the eternality of matter. Scripture is very clear: “In the beginning God…”. On this point, the classical, confessional Reformed theologians built their distinction . . . Continue reading →
Heidelcast 123: I Am That I Am (1)—The Categorical Distinction
This is the 1st episode of our series on the doctrine of God, ““I AM That I AM.” In older histories of theology it used to be said of the Reformed that they started with the divine decree and deduced (i.e., drew . . . Continue reading →
Heidelcast 122: Rise, Make For Us Gods (With Chris Gordon)

Heidelcast 120: D. G. Hart On H. L. Mencken
Henry Louis Mencken (1880-1956) was one of the most influential writers of the 1st half of the 20th century. He was a skeptic about religion but had a keen eye and a sharp tongue. It was he who described Sister Aimee’s religion . . . Continue reading →
Heidelcast 119: I Will Be A God To You And To Your Children (14)
This series has really been about how to interpret Scripture. Christians study the same Bible, but we often read it differently. Sometimes we begin with different assumptions about the nature of things and authority. These different methods and starting points lead to . . . Continue reading →
Heidelcast 118: I Will Be A God To You And To Your Children (13)
With this episode now we dive into the question of baptism itself. So far we have been setting the stage because, from the historic, confessional Reformed point of view, the debate about infant baptism is really a debate about how to understand . . . Continue reading →

We are interrupting our series on covenant and baptism to talk to a special guest, Les Lanphere. He is one half of the Reformed Pubcast and co-moderator of the Reformed Pub on Facebook. He’s also a film maker and he is in . . . Continue reading →
Heidelcast 116: I Will Be A God To You And To Your Children (12)
We are just about ready to immerse ourselves, as it were, in the question of baptism but we have at least one more thing to discuss before we get to baptism and that is this: what is baptism? In the Reformed tradition, . . . Continue reading →
