Eph 2:8 - the "faith" used in this scripture, is Jesus's faith, not man's. "and that not of yourselves" reinforces it.
Actually, it doesn't, because neither the sentence structure nor the context permit that conclusion. Nowhere in the preceding 30 verses does "the faith of Christ" appear.
Let's see what chapter 1
does say:
12 That
we should be to the praise of his glory,
who first
trusted in Christ.
13 In whom
ye also
trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that
ye believed, ye were sealed with that holy Spirit of promise,
...
15 Wherefore I also, after I heard of
your faith in the Lord Jesus, and love unto all the saints,
...
19 And what is the exceeding greatness of his power to
us-ward
who believe, according to the working of his mighty power,
We who trusted in Christ,
ye trusted,
ye believed,
your faith in the Lord Jesus,
us who believe. Does that sound like "the faith of Christ", or the faith of humans
in Christ?
Let's look again at chapter 2:
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.
Paul is contrasting faith with works. Let's pause here to ask
whose faith and works? Is Paul contrasting the faith of Jesus with the works of Jesus? Are we saved by Jesus' faith but not by Jesus' works? I hope you agree that whole question is silly.
Rom 5:1 - This scripture harmonizes with Gal 2:16, if you do not change the wording of the scriptures.
Let's see...
KJV
Romans 5:1 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:
Galatians 2:16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
Yes, they harmonize, but that harmonization does not support the idea that Jesus' faith is that which justifies.
-NIV
----Rom 5:1 Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ,
----Galatians 2:16 know that a person is not justified by the works of the law, but by faith in Jesus Christ. So we, too, have put our faith in Christ Jesus that we may be justified by faith in Christ and not by the works of the law, because by the works of the law no one will be justified.
These harmonize perfectly.
-NASB
----Rom 5:1 Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ,
----Galatians 2:16 nevertheless, knowing that a person is not justified by works of the Law but through faith in Christ Jesus, even we have believed in Christ Jesus, so that we may be justified by faith in Christ and not by works of the Law; since by works of the Law no flesh will be justified.
As do these.
The newer versions harmonize
far more clearly than the KJV.
Regarding your comment "if you do not change the wording of the scriptures", nobody
changed them; they translated them differently. You would have to establish that the KJV is the original wording (good luck with that) before you can make the charge that anyone "changed" them.
