Heidelberg 64: Sanctification By Grace Versus Sanctification By Scolding (1)

Usually, if a boss wants greater efficiency and productivity from her employees, she sets up a system of incentives for her employees. If the boss is of the ordinary, uncreative sort, those incentives are likely to be negative. Fail to meet this goal and x (e.g., loss of pay, demotion etc) shall happen. A more creative boss might set up a series of positive incentives: meet this target and you shall receive y reward (e.g., extra paid vacation, flexible scheduling, company car etc). Whatever the nature of the incentive, the very structure is a covenant of works. Continue reading →

Heidelberg 63: Rewards Merited For Us By Christ And Given Freely To Believers

When the medieval church thought about rewards, it thought about merit. They distinguished between two kinds or aspects of merit. That which we most frequently discuss was called “condign merit” (meritum de condigno). Condign merit is intrinsically worthy. The second category was “congruent . . . Continue reading →

Heidelberg 65: Faith, Union With Christ, And The Means Of Grace (3)

Neither Holy Baptism nor the Holy Supper create the realities they signify and seal but they are gospel sacraments. They are promises of good news to believers. Faith receives what they promise.

They confirm faith the way a registered letter embossed or stamped with a government seal confirms a declaration. Continue reading →

Hungarian Reformed Churches: Instruments Are Shadows

Now that Christ has come, and together with the ancient priesthood and sacrifice and the representation appertaining to the Law, the use of instruments in churches has vanished like a shadow…There is not so much as a reference to the organ in the New Testament, nor of its introduction into the purer church; but it was only introduced in theatrical masses, as if in obscene sport, by immoral priests to make clowns cut capers.

Office Hours: Wisdom In Preaching

Office Hours

Our Lord Jesus worked miracles but he was also a preacher. He came “preaching the Gospel of God and saying ‘The time is fulfilled,’ and ‘Kingdom of God is at hand, repent and believe the gospel’” (Mark 1:15). People marveled at his . . . Continue reading →

Considering Context Leads To Singing Psalms In New Testament Praise And Worship

Context inevitably colors how we understand texts. It shapes our assumptions about what about what is possible and plausible. I see this in Patristics (the study of the early Christian church). As a confessional Reformed Christian with connections to Reformed orthodoxy, as . . . Continue reading →

Heidelberg Catechism: The Fall Was Law Breaking

7. From where then comes this depraved nature of man? From the fall and disobedience of our first parents, Adam and Eve, in Paradise, whereby our nature became so corrupt that we are all conceived and born in sin.   —Heidelberg Catechism
