Shared ground
Paul is not saying the Christian message has no wisdom. He says he does speak wisdom, but it is a different kind than the wisdom that wins status in “this world” (this present age) and among its top decision-makers.
This wisdom is explicitly called God’s wisdom. It was not obvious to ordinary human evaluation, because it was “hidden” and described as a “mystery”—something God had in view and later brought to light, rather than something people could confidently infer from public power and success.
Paul also ties this wisdom to God’s long-range plan (“before the worlds/ages”) and to an outcome he summarizes as “to our glory” (glory). The rulers’ failure to recognize it is highlighted by the crucifixion of Jesus, whom Paul calls “the Lord of glory.”
Where interpretation differs
Who are “the mature/full grown”? Some read this as a spiritual category: people shaped enough by the message of the cross to grasp its “wisdom.” Others hear a more basic contrast: believers versus outsiders, since the surrounding context contrasts God’s revelation with normal human evaluation.
Who are “the rulers of this world”? Some take this mainly as human authorities involved in Jesus’ death (local and imperial leadership). Others think Paul also has in mind broader “powers” behind political structures, since he speaks of “this age” and of rulers “coming to nothing.” The passage itself stresses their real-world role in crucifixion, but its language can sound wider than one courtroom.
What does “coming to nothing” mean? Some understand it as their eventual collapse/irrelevance in God’s plan (their supposed wisdom will not last). Others hear a stronger claim: their authority is being nullified already through what God has done in Christ.
Why the disagreement exists
Paul compresses several big claims into a few lines (“this age,” “rulers,” “mystery,” “glory”). Those terms can be read narrowly (mostly about human leadership and historical events) or more broadly (including unseen forces and an already-started overturning of power). The immediate evidence he gives—“they crucified”—leans historical and concrete, while the bigger framing (“before the ages,” “to our glory”) pushes readers toward a larger horizon.
What this passage clearly contributes
Textually, Paul’s claims are clear: (1) he speaks wisdom “among the mature,” (2) that wisdom is not sourced in the present world’s status system or its rulers, (3) God’s wisdom was hidden and planned long ago, (4) it aims toward “our glory,” and (5) the rulers’ ignorance is exposed by their role in crucifying the “Lord of glory.”
Theologically (by inference), the passage supports the idea that God’s plan in Christ runs on a different logic than public power, and that the cross is not a setback to God’s purpose but the event through which the world’s leaders showed they did not truly “know” what God was doing (1 Corinthians 2:6–8).
