Did Ursinus Teach Final Salvation Through Works?

by on April 21, 2020

Zacharias Ursinus (1534–83) was the principal author of the Heidelberg Catechism (1563). He was responsible for perhaps as much as 70% of the catechism, though the two source documents that he created, from which much of the catechism was formed, drew from many sources (including Luther), so the source criticism of the catechism is challenging. For more on the background of the catechism see Lyle Bierma et al ed., An Introduction to the Heidelberg Catechism: Sources, History, and Theology (2005) and J. I. Good, Good, The Heidelberg Catechism in Its Newest Light ( Philadelphia, PA: Publication and Sunday School Board of the Reformed Church in the United States, 1914). Continue reading →

The Reasons Christians Do Good Works

by on April 21, 2020 | 1 Comment

The Heidelberg Catechism is in three parts: Law, Gospel, and Sanctification or Guilt, Grace, and Gratitude. This is not an artificial interpretation of the Catechism nor is it an artificial arrangement of the Christian faith. Question 2 outlines the Catechism for us: Continue reading →

Saved Through Good Works?

by on April 20, 2020 | 1 Comment

In Reformed theology the noun salvation is typically used in two ways. Sometimes it is used as a synonym for justification. When used this way it does not include sanctification since, according to the Reformed confession, justification is a declarative act of God whereby he credits (imputes) to sinners the perfect, active and suffering righteousness of Christ so that it is as if those sinners to whom Christ’s righteousness has been so imputed are considered to have themselves accomplished personally all the Christ did for them as their substitute. Further, we say that this benefit is received through faith alone (sola fide) defined as trusting, resting in, and receiving Christ and his righteousness. We confess that both the imputation of Christ’s righteousness and faith as the receiving instrument are nothing but God’s free gifts. Hence we attribute all of this to God’s favor (grace) alone. The slogan for this is sola gratia, by grace alone. Continue reading →

How disgraceful it is for a servant of Christ not to know the command of His Lord, and to pursue some other, useless preoccupation, and fail to take an interest in the things which concern His Lord, who is our everlasting blessedness! . . . Continue reading →

New Resource Page: Natural Law

The Reformed theologians and churches have held, taught, and confessed the existence of natural law since the earliest days of the Reformed Reformation in the 1520s. If all one knows, however, of Reformed theology is 20th century (or 21st-century) Reformed theology, one . . . Continue reading →

New Resource Page On The Belgic Confession

by on April 17, 2020

The Belgic Confession is one of the jewels of the Reformed Reformation. Largely derived from the French Confession (1559), the Belgic, nevertheless, has an identity of its own. Based on a series of sermons and drafted by Guy de Brès (1522–67), who . . . Continue reading →

New Resource Page On The Reformation Solas

by on April 17, 2020

The Reformation was, at its core, the recovery of the biblical doctrine that Scripture is the only final authority (sola Scriptura) for the Christian faith and the Christian life, that salvation is by divine favor alone (sola gratia), through faith alone (sola . . . Continue reading →

ICYMI: Indulgences Are Still A Thing In Rome (And The Reformation Still Matters)

by on April 13, 2020 | 1 Comment

The Reformation was a complex event, which happened for many reasons but the triggering event on which many have focused over the centuries was Martin Luther’s Ninety-Five Theses (1517). Though provocative, theses were not themselves all that radical. Luther’s discovery of the basics . . . Continue reading →

The Resurrection And Your Anxiety

by on April 12, 2020 | 3 Comments

When the Sabbath was past, Mary Magdalene, Mary the mother of James, and Salome bought spices, so that they might go and anoint him. And very early on the first day of the week, when the sun had risen, they went to the tomb. And they were saying to one another, “Who will roll away the stone for us from the entrance of the tomb?” And looking up, they saw that the stone had been rolled back—it was very large. And entering the tomb, they saw a young man sitting on the right side, dressed in a white robe, and they were alarmed. And he said to them, “Do not be alarmed. You seek Jesus of Nazareth, who was crucified. He has risen; he is not here. See the place where they laid him. But go, tell his disciples and Peter that he is going before you to Galilee. There you will see him, just as he told you.” And they went out and fled from the tomb, for trembling and astonishment had seized them, and they said nothing to anyone, for they were afraid (Mark 16:1–8; ESV).
