Interestingly enough, you can actually view the text of the
Ecumenical Grail Psalms and the
Revised Grail Psalms on the GIA website.
Here’s Psalm 1:1–2 in the RGP:
1 Blessed indeed is the man
who follows not the counsel of the wicked,
nor stands in the path with sinners,
nor abides in the company of scorners,
2 but whose delight is the law of the LORD,
and who ponders his law day and night.
And here it is in the EGP:
1 Blessed indeed are those
who follow not the counsel of the wicked,
nor stand in the path with sinners,
nor abide in the company of scorners,
2 but whose delight is the law of the LORD,
and who ponder God’s law day and night.
It looks pretty similar except for the inclusive language in the EGP.
