Some time ago I posted about those who attempt to reduce Christian teaching to Christ crucified and nothing else. I have personally been attacked by certain people who grossly misunderstand what Paul says in 1st Corinthians 2:2.
I recently came across John Frame’s explanation of this concept that I found worthy of reproducing for you.
So we should not take “Christ and him crucified” in a reductive sense, as if our preaching and teaching must be confined to the person of Christ and the atonement. Indeed, Paul in 1 Corinthians and his other writings, as well as his sermons in Acts, discusses many other subjects: factionalism (1 Cor. 1:10–17; 3:1–23), wisdom (1:18–26), the nature of the apostleship (4:1–21), sexual immorality (5:1–13; 6:12–20), lawsuits (6:1–11), marriage (7:1–29), food offered to idols (8:1–11:1), worship (11:1–34; 14:1–40), spiritual gifts (12:1–31), love (13:1–13), our own resurrection (15:1–58), collections for the saints (16:1–4), Paul’s personal plans (16:5–21). “Christ and him crucified” is not a boundary, but a center. Though Paul speaks of many things, in the end it all traces back to Christ. (John M. Frame (2014-09-05). Systematic Theology: An Introduction to Christian Belief (Kindle Locations 22831-22837). P&R Publishing. Kindle Edition.)
So to be “Christ-centered” is not to speak only of Christ, ignoring all the effects and applications of his work. Christ-centered preaching is not preaching that limits itself to the events of the history of redemption and eschews the applications of his work to marriage, suffering, anxiety, wealth, and poverty. Neither Jesus nor Paul restricted the gospel in that way, and we should not do so either. Christ is a great light that shines into every corner of human life, because he is Lord of all. (John M. Frame (2014-09-05). Systematic Theology: An Introduction to Christian Belief (Kindle Locations 22842-22845). P&R Publishing. Kindle Edition.)
Thank you, Dr. Frame.
