You are misinformed if you believe salvation is first and last found anywhere but He on the Cross.
The bare cross is quite barren of Salvation, without Him.
A discussion of your resurrection without Him first on the Cross is secondary without that Work.
Salvation is found THROUGH the cross, not Jesus forever dead hanging on the cross.
Jesus DIED. He rose from the dead.
The cross is empty because His work is FINISHED. He’s not still dead hanging on the cross forever.
He’s risen, glorified, and seated at the right hand of the Father in heaven now.
If your Jesus is still hanging on the cross, dead, then He was not buried, He is not risen, and He did not conquer death.
Your argument is with the Scripture that you claim your church wrote. And I think that Saint Paul is a better theologian than any lay Catholic.
