In summary: celebrating Holy Mass in the traditional manner, ad orientem, which Cardinal Ratzinger has called "not something accidental" but "a rediscovery of something essential, in which Christian liturgy expresses its permanent orientation," is at the very least a legitimate option "in accord with liturgical law" and "to be considered correct." No bishop is able "to exclude or mandate the use of a legitimate option."
Which Way to Turn? A Tale of Two Citations October 10, 2001
By Rev. Joseph Fessio, SJ
o WASHINGTON, DC (CNS)--The Vatican Congregation for Divine Worship and the Sacraments July 28 issued the first revision in 25 years of the General Instruction of the Roman Missal.
The new Latin-language instruction--released simultaneously in Washington in an English study translation--introduces numerous minor changes in the way Mass is to be celebrated.
It also makes a clear legislative decision on a controversy of recent years by declaring that it is "desirable whenever possible" for the priest to celebrate Mass facing the people.
o But what about the altar? In what direction should we pray during the Eucharistic liturgy? … When the altar was very remote from the faithful, it was right to move it back to the people…. It was also important to distinguish the place for the Liturgy of the Word from the place for the properly Eucharistic liturgy…. On the other hand, a common turning to the east during the Eucharistic Prayer remains essential. This is not a case of something accidental, but of what is essential. (Cardinal Joseph Ratzinger, The Spirit of the Liturgy, Ignatius Press, 2000.)
Can these two citations be reconciled? What is the mind of the Church? Is it "essential" to face east during the Eucharistic Prayer? Or has there been a "clear legislative decision" that it is undesirable?
