Shared ground
Hebrews 2:9–10 says Jesus truly entered a lowered human condition (“a little lower than the angels”) and then is “crowned with glory and honor” because he endured death’s suffering. The text treats his death as a real, personal experience (“tasted death”) and says it happened “by the grace of God” and “for everyone.”
It also says this path matches God’s purpose. God—described as the one “for whom” and “through whom” all things exist—is “bringing many sons to glory,” and God brings the “leader” of their deliverance to completion “through sufferings.” The passage connects Jesus’ suffering with God’s plan to bring many others to glory.
Where interpretation differs (only where needed)
1) What “a little lower than the angels” means. Some read it mainly as a temporary stage (Jesus was lowered for a time in becoming human). Others think it includes a real status of lowliness, not only a time marker (sharing human weakness and vulnerability).
2) What “for everyone” means. Some take “everyone” to mean every human being without exception (the death is for all). Others read it as “everyone” within the group God is bringing to glory (the death is for all those who become part of the “many sons”). Either way, the text itself stresses broad scope and representative action.
3) What it means that God made the “leader” “complete” through sufferings. Some hear this as role-completion: suffering qualifies Jesus to fully function as the saving leader he is. Others worry it could imply a change in Jesus’ inner moral quality; they answer that the wording is about reaching the intended goal of his mission rather than correcting a flaw.
Why the disagreement exists
The key phrases can naturally be taken in more than one way without changing the basic storyline. “A little lower” can point to time or to status. “Everyone” can be read in a maximally inclusive sense or in a context-limited sense (“many sons”). And “made complete” can mean “made morally perfect” in everyday English, while in context it can mean “brought to full fitness for a role.”
What this passage clearly contributes
Explicitly, the passage teaches that Jesus’ exaltation is tied to his suffering and death, not despite it. It portrays his death as gracious and representative (“for everyone”) and frames the whole movement as consistent with God’s wise purpose: God is bringing many into glory and has a “leader” who reaches his mission’s full goal through suffering. The passage also reinforces Hebrews’ larger theme that Jesus shares the human condition while remaining the one through whom God brings others to their intended destiny (see Hebrews 2:8–9).
