There is a lot in this canon as well.
either by the sole imputation of the justice of Christ
This is saying...
If one believes justification comes from imputed transfer.......or imputed righteousness
This is building a case for "Infused grace"
The RCC says grace is given and we remain in a state of grace only as long we continue in
cooperation,
{synergistic} with the infused righteousness of that grace. Grace is a supernatural gift, meaning it does not come from us, our bodies cannot make it, but it can dies, or be hurt by our sin. So if we do not
cooperation with grace, it will not remain with us.
The RCC does not teach that our relationship with God continues FULLY after we sin. It does not undo baptism, which they teach does away with the sin nature. (If I understand it right). but the grace we once had is damaged. So the RC must reestablished by the sacrament of reconciliation. They must confession the sin, repent, and ask forgiveness.
Reformers saw God as a father, who continues to care for the elect even when they sint. Like a human father, he does exercise discipline. This is unconditional love. We still are in a state of righteousness because our righteousness is not based on what we do. It is based on what Christ has done, and his righteousness is given to us...placed on us..imputed.
We remain in a state of grace only as long as by our continuing cooperation, this infused righteousness continues to be present. It is a supernatural gift, meaning that it's not something we could develop on our own. That's the reason that it ceases to be present after mortal sin.
The Reformed view says that "imputed righteousness" or "forensic justification"represents Christ's righteousness being accredited to our account even through we NOTHING.
While I am a Calvinist and John Calvin was the one that set this doctrine in words for the church so I disagree with the RCC, at least they don't jump back and forth on synergist teaching. Some, hav god in full control at times, and other times man must work with God.
