Some, following Luther, have questioned whether James is part of Scripture.
I take the view that it is part of Scripture, as do virtually all the Reformers after Luther and all the Reformers before Luther.
An objector asserted various points against James.
1) That it contradicts Paul's epistles and can only be reconciled by mental gymanstics.
2) That it was not relied upon for the first 400 years of the church.
3) That James was notoriously anti-Pauline, citing the proceedings of the council of Jerusalem.
I disagree with each of these contentions.
In terms of early use of James' epistle in the church, Irenaeus (died 202), "Against Heresies" Book IV, Chapter XVI quotes James 2:23.
In terms of reconciling James and Paul, James speaks of justifying oneself in the eyes of men ("show me thy faith") whereas Paul speaks of justification before God ("... by the deeds of the law there shall no flesh be justified in his sight..." ... "if Abraham were justified by works, he hath whereof to glory; but not before God." ... "no man is justified by the law in the sight of God,"). Thus, Paul explains the importance of faith in salvation, and James explains a way to identify whether we and others have faith (and therefore have been saved), teaching what the Lord taught: "by their fruits ye shall know them." After all, the engrafted word will bear fruit in us.
As it is written "... the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart." 1 Samuel 16:7
I'm not sure if the objector views that as gymnastics - but I don't think it is.
As for the council of Jerusalem, we see James' instruction in Acts 15:20 of what to write. We see it being written in Acts 14:29 (with an assertion that it is inspired in verse 28), and we see confirmation that it was written in Acts 21:25 and we see Paul confirming by deed his submission to the Holy Spirit in Acts 21:24-26.
In fact, while Paul was not afraid to oppose Peter and to record his opposition in Scripture, there is no record of Paul and/or Barnabus opposing the council. Instead, we see that they were sent out by the council (headed by James) and they came back and reported back to the council.
So, I do respectifully disagree with the objections, and I do not believe that they are factually supported.
Nevertheless, I welcome any comments.
May the God of peace bless all of us,
P.S. Today, James Swan has posted an interesting article that touches somewhat on this issue, and is worth reading:
