You are making the same mistake over and over again. We have told you numerous times that we are not saved by the Mosaic Law and neither was David or any other OT figure. Everyone from both the old and new covenants is saved by Jesus.
You are attempting to paint us as legalists, and this simply will not fly. If you think that David or any other person of the OT that committed grievous sins such as murder would be saved without repentence then you do not have a grasp of the OT scriptures. Try reading Psalm 51 where David asks for God’s mercy and forgiveness.
I will attempt one last time to explain the relationship issue that is crucial to understanding why we cannot engage in sinfulness and expect to be saved. This explanation is something that we partially share with our non-Catholic brothers and sisters, but it is something that is not well articulated or sometines understood on their part.
Catholics do not believe that we are saved by keeping the ten commandments. Please lock that into your consciousness before we proceed.
We are saved by the redemptive work of Christ on the cross. He is the redeemer and we are the redeemed.
God gives us grace to believe and to thus receive the application and benefit of that redemptive work of Jesus as a free gift.
It is by this that we come into the right relationship with God through grace by faith. In other words we become “justified.” Please lock that into your consciousness before we proceed.
We are at that point in time a "new creation in Christ Jesus for good works which the Father prepared beforehand*
We are not a new creation in Christ Jesus for breaking the ten commandments or for any form of evil.
We are now in a family relationship with God as “Abba” Father. Jesus is our brother. The Holy Spirit dwells within us. Sin and God are not compatible with one another.
The law and the decalogue point out sin but have no saving power.
Grace has power and that is why Phillippians 2:12-13 says:
“Therefore, my beloved, as you have always obeyed, so now, not only as in my presence but much more in my absence, work out your own salvation with fear and trembling; for God is at work in you, both to will and to work for his good pleasure.”
Paul likewise tells us in Romans “…that we are to be conformed to the image of His Son[Jesus]”
Sin is not the work of God within us, and is not the will and work for the good pleasure of God. Sin does not conform us to the image of Jesus. God’s grace saves us and changes us.
The “royal law” per James, and the “law of Christ” per Paul, are one in the same thing. They have to do with grace and being members of the family of God. They have to do with “being righteous” The apostle John puts it this way:
1 John 3:7
“Little children, let no one deceive you. He who does right is righteous, as he is righteous.”
John doesn’t tell us to break the ten commandments or to sin. Instead, he tells not to sin[see all of 1 Jn 3] Likewise, Paul and James don’t tell us to break the ten commandments either. Instead, they tell us that as Christians living in the Spirit that we actually uphold the law. They say this because loving God and neighbor fulfill the law and righteousness which is the “royal law” and the “law of Christ.”
It isn’t the letter of the law. It isn’t legalistic. It’s all about living in the Spirit, by way of the Spirit, living in Christ, living by grace, doing the works of the Father by way of grace in our new creation in Christ Jesus. Sin is incompatible with this life in Christ.
Legalism is dead but so is our life in sin*. It is in this last point, that we actually uphold the law by faith in Jesus Christ.
The wages of sin is still death[Rom 6:23]. We are finished with sin[Rom 6:2] We are no longer enslaved to sin; we are freed from it. We are freed from breaking the decalogue. We live to the Father, Son, and Holy Spirit and we do this as adopted sons and daughters, and brothers and sisters in Christ by way of grace.
It is all about relationship. In our family relationship as Christians we cannot be members of the holy household if we live a life of sin. Fornication, murder, thievery and the like are banished and cannot be part of our lives. The prodigal son left the Father’s household in order to live a life of dissipation in the flesh. He could not live that life within the household of grace. He had to turn from the life in the flesh and return to the household in repentence.
That is why James says, “My brethren, if any one among you wanders from the truth and some one brings him back, let him know that whoever brings back a sinner from the error of his way will save his soul from death and will cover a multitude of sins.”[James 5:19-20]
That is also why Jesus says, “Just so, I tell you, there will be more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance.”[Luke 15:7]
This joy in heaven is in keeping with the feast offered by the father for the prodigal son “who was dead but is now alive.”
