“Redemptionism: The doctrine that all of humanity was redeemed (i.e., saved, sanctified) through the death and resurrection of Jesus Christ and asserting that the redemption of all was completed and concluded in his resurrection.”
There are some very plain teachings in the NT that blow that doctrine to smithereens. However, the tactic of avoiding those teachings by claiming they do not apply to us does eliminate the smithereening: but at what cost ? And what is the basis of that tactic?
Especially - all of humanity was SANCTIFIED by the death and resurrection of Jesus? Sanctification is a process, not a gift, and it is our high privilege to work out our salvation.
Work out our salvation - it actually says that in the NT post-resurrection. We are not saved by our ‘works’ - I don’t know anyone who believes that - but certainly our call is to life-long faithfulness - stemming from God’s faithfulness - and as Paul said “seeking glory and honor etc.” through well-doing.
I’m still working on understanding. Maybe if I wasn’t so deep into Romans right now this would not be pushing any buttons; but I am, and feeling the weight and wisdom of Paul, I think there are some real misunderstandings here. However, if the scriptures are not on the playing field because they are ‘not for us’, we have no chance of convincing each other.
