Regarding the Chaldean Church, the Holy Synod recently approved a liturgical reform that accomodates the liturgy more according to the Assyrian practice, they have removed many Tridentinizations (the words "mystery of faith" in the consecration) and have restored the traditional possition of the priest facing the altar when celebrating the liturgy, at least during the second part of the liturgy.
http://www.kaldu.org/14_Reformed_ChaldeanMass/ReformEssay.htmlI think all will applaud the removal of Tridentinizations. However, it is also clear from the presentation of the Chaldean "liturgical reform" -- which, according to the essay quoted, is only in the first of three projected stages -- that the Chaldean Divine Liturgy has had some of its "inconsistencies" and "redundancies" eliminated, including supposedly repetitive prayers and merely "devotional" prayers (such as the the prayers before Communion and the "Kushape", which is reminiscent of the Franco-German "Apologiae" which existed in medieval Latin Missals). Many very old liturgical rites -- many of them apparently more than a millenia old -- were removed in order to "conform" to the writings of certain Syriac commentators.
Meanwhile, the Assyrians continue to use the "unreformed" liturgy, neither "Tridentinized" nor "Reformed and Purified":

Compare this with the Reformed Chaldean Mass:

All of this might seem innocuous at first, but for Latin-rite Catholics like me, this rings alarm bells. The reform of the Chaldean Mass proceeds along principles directly borrowed from the Roman liturgical reforms of the 1950's and 1960's.
The principles being used to reform the Chaldean Mass are exactly the same as those which were used to begin the reform of the Roman Liturgy in the late 40's and early 50's, leading to the 1955 Reform of Holy Week (further "reformed" in 1957, 1959 and 1960 and now embodied in the 1962 Missal) which even traditionalist liturgists loyal to Rome consider to be a liturgical disaster, hence the increasing number of requests for indult to celebrate according to the pre-1955 and not the 1962 Holy Week. Of course, it didn't end there, but led onwards to the 1969 Novus Ordo.
But what are these principles? These are:
1) Archaeologism / "Repristination" -- rites that are themselves already ancient are removed in order to conform to what was said to have been in place in the first centuries of Christian antiquity.
2) The removal of "accretions" and "redundancies" which are supposed to have no value. Much of the Chaldean reform consists of the elimination of these. Frankly, is the threefold repetition of the Our Father -- which existed in the old Chaldean liturgy but now removed -- such a bad thing? And is the removal of the remnants of the ancient monastic psalmody from the beginning of the liturgy -- as has now been accomplished in the new Chaldean liturgy -- really necessary?
3) "Rationalizations" of the Rite -- removal or rearrangement of ceremonies that are said to have little or no meaning in their current assignations.
4) Simplification and shortening of rites
Roman Catholics have had the hard and painful lesson in the past 40 years of knowing that these principles can, in the end, cause great harm for the liturgy of the Church. Much of the best liturgical scholarship of the past decade has shown that many "redundancies" and "irrational" elements in the old liturgies -- Eastern and Western -- actually have very rich meanings and are of great value. And here are the Chaldeans imitating the Roman reform... albeit without the "ad populum".
Eastern Christians, please, think LONG AND HARD before you imitate us Romans!
Just imagine what would happen if the principles of the Roman and Chaldean reforms were to be applied to the Byzantine liturgy....

At the very least, I hope that the CHaldean liturgical reform commission is dead-on accurate about all their info on the ancient East Syrian liturgy. Please remember that many of the Latin-rite liturgical reforms of the 1950's and 1960's purported to revive ancient patristic features in the liturgy -- features that, in the 1980's and 1990's, were proven to have existed only in the imagination of the liturgical reformers themselves.
