text: Proper canon law answer is that this rite is both valid and licit.
  
    In 2001, seven years after the Vatican's common declaration of faith with the (formerly Nestorian) Assyrian Church of the East, the Pontifical Council for Promoting Christian Unity issued its Guidelines for admission to the Eucharist between the Chaldean Church and the Assyrian Church of the East, in order to improve relations between Catholics and schismatics of the Chaldean rite. This document is most noted for its surprising affrimation of the sacramental validity of the Assyrian anaphora of Addai and Mari, a Eucharistic Prayer that does not literally recount the words of Christ at the Last Supper. The product of years of careful analysis, this declaration has been widely misinterpreted, though understandably, as denying the Church's millennial doctrine that the words of Christ spoken by the priest are the form of the sacrament that effects transubstantiation.
