No, not the Mass of Paul VI. The Chaldean Catholic Church, which apparently has a very chaotic liturgical situation, is in the midst of promulgating new texts for the celebration of Mass. They are calling it a "New Mass," but being no expert in the Chaldean rite I cannot say how much is this is genuine restoration, de-Latinization, neo-Latinization, or, as they are saying, a "return to our roots." This article, which covers the more pastoral points of the reformed liturgy, indicate that ad orientem worship will be restored as a mandatory rubric! I wish the Chaldeans well!
