A couple weeks ago, we were pleased to visit a PCA church while travelling that used the PCA/OPC Psalter. This is the first time I was aware of this- it looks just like the Hymnal.

Is it different from the Scottish Psalter in regards to wording, etc.?
Yes, quite.

Having had about a month now to look at the new Psalter, I must say that there are a few things in it that are disturbing to me:
1. From Psalm 8: "Yet You created him to be Just less than one divine; You gave him honor as a crown and made his glory shine".
This suffers under two problems in my opinion 1)It is a flat contradiction of the inspired interpretation of this Psalm in Hebrews 2 and lends itself to an Arian reading if somehow one tries to reconcile it to Hebrews 2. I could not sing this verse in good conscience. 2) You will notice the "him" is not capitalized. Now I have never been a fan of the NKJV cpatilization of references to the divine (the same sort of idea applied in the psalter) because it leads to confusion. By not capitalizing the "he" the "translators" of this psalm are indicating they do not believe it is a Messianic reference (again contra Hebrews 2). Doubly problematic.
2. From Psalm 24B: "Hallelujah, Hallelujah, Hallelujah, Hallelujah, Hallelujah, Amen, Amen, Amen." This is
not found in Psalm 24. This is an unispired addition to this psalm rendering. For shame. In my opinion this is not only dangerous it is flat out dishonest.
3. From Psalm 150D: "O Praise Him! O praise Him! Allelujah! Allelujah! Allelujah! Allelujah!" Again this is an
insertion into the psalm. How can people promoting exclusive psalmody not see the disingenuity here?
4. There are various other places where the historic Reformed understanding of verses has been translated away. But for the moment, I forebear.
I caution people very strongly before buying into this new psalter just because it is new. Old doesn't always mean better, I admit. But neither does new.
