I voted never. It's not that I never have. It's just that I never will. I only attend the Traditional Latin Mass after SOOOO many years of the Novus Ordo Mass (post-Vatican 2 Mass). It's is a long story about how I got to the point of being a (as they say) Traditional Catholic. But, it is the sure way.
Without opening a can of worms...unless I just did =) ... I must respectfully correct Trigger in her statement:
Vatican II reforms were instituted to make the rituals and Sacraments more open & accessible to the Communicants/the Body of the Church (i.e., the congregation). Prior to that, Mass was more like a "priest's performance" and there wasn't a lot of active participation from the congregation ... the priest even celebrated Mass with his back to the community.
Jesus didn't celebrate the Last Supper above and beyond His disciples, turning His back to them. He literally surrounded Himself with them, washed their feet, and then fed them - spiritually as well as physically. He was their humble servant.
I am not too good with words or apologetics. But, I know what is true. Please read this brief info about the WHYs of our faith. The more you can know about the Catholic faith and its origins, the richer your faith life will be. I have pasted this info below but, also, here is the link: http://frcoulter.com/presentations/ad-orientem.html
Besides the change in the Mass after the Second Vatican Council, we have learned that Latin is still used by the Church and has a proper place in our worship. Therefore I want to discuss a second change made after 1965, the direction which the priest faces during Mass. We will examine three points: one, what is the teaching of the Church about the orientation of the priest at Mass; two, what is some of the history and tradition of the priest facing toward the East; three, what can the priest's position teach us about the Mass and our participation in it.
What does the Church teach about the priest's orientation at Mass? After the Second Vatican Council, one most evident change was the construction of freestanding altars. The celebration versus populum (towards the people) was adopted throughout the Latin Church, and it became the prevailing practice during Mass for the celebrant to stand behind the altar facing the congregation. This has led to a widespread misunderstanding that the priest's "turning his back on the people" is characteristic of the Tridentine rite, the old Latin Mass of Pope Saint Pius V; whereas the priest's "turning towards the people" belongs to the New Mass of Pope Paul VI. It is also widely thought that the celebration of Mass "facing the people" was required, even imposed, by the liturgical reform of Vatican II.
In reality, the Council did not even mention the issue, only an instruction afterwards said it was desirable to set up a main altar separate from the back wall, so that the priest can walk around it and a celebration facing the people is possible. Contrary to what often took place, the Church never instructed that the old high altars should be torn down, rather that a freestanding altar should be present in the sanctuary - perhaps in addition to the high altar.
The Sacramentary we use, the Missal of the renewed Mass, it gives the instruction at several points during Mass that the priest should turn towards the people.* In order for the priest to turn towards the people, this implies that beforehand the priest and people were facing a common direction, that is, towards the altar for the core of the Eucharistic liturgy.
So why did the priest used to always celebrate Mass facing the other direction? What is the reason for this orientation?
The first thing to remember is that the Eucharistic sacrifice is offered to the one and triune God, just as all Christian prayer is an act of worshipping God. So how this can be communicated most fittingly in liturgical gesture? When we speak to someone, we obviously face that person. Accordingly, if whole liturgical assembly, priest and people, face the same way, they turn towards God to whom prayers and offerings are addressed in this common act of worship. It is a mistaken idea that in this case the celebrating priest is facing "towards the altar", "towards the tabernacle", or even "towards the wall". (cf. Ratzinger, Feast of Faith: Approaches to a Theology of the Liturgy (San Francisco: Ignatius Press, 1986), 139-143)
I have often heard the phrase that Mass is being celebrated with the priest "turning his back on the people". This is confusing theology with physical position. The crucial point is that the Mass is a common act of worship where priest and people together, representing the pilgrim Church, reach out for the transcendent God. The priest isn't turning his back on the people; he is joining the people in prayer. At Mass, all of us are praying together to God through Jesus Christ. Whether the priest celebrates towards the people or not, all of us - both you and me - are turned towards God as our first spiritual movement in prayer.
The physical position must be distinguished from the interior spiritual orientation of all. It would be a grave error to imagine that the principal orientation of the sacrificial action is towards the community. (CDW, 25 September 2000, Cardinal Jorge Arturo Medina Estévez)
Notice that during the Eucharistic prayer, the prayers are not addressed towards you - but to the Father. At that moment in the Mass, the priest is not speaking to the faithful; he is offering prayer to the Father as a representative of the entire Church.
This is why, since the earliest times, Mass has been celebrated with both the people and priest facing the same direction, ad orientem, toward the East. Even after Churches were built where it was not literally possible to face East, then at least symbolically the priest and people were turned toward the Lord. It had nothing to do with trying to obstruct people's view of what is happening, or of the priest turning his back on the people. Nor is it even primarily for the sake of facing the altar or tabernacle. Rather, when the priest and faithful together face the same way, it manifests our common act of worship; it symbolizes our common pilgrimage toward the returning Lord, the Sun of Justice and our hope in the resurrection and the world beyond the here-and-now, our pilgrimage to the Promised Land.
Furthermore, it is with a heart of charity that I point you toward more information about our beautiful faith. I wish someone had told me 20 years ago (or more!) what I have just come to know in the last 3 or 4 years. I don't want to derail this thread. But, if you are serious about your Catholic faith, please read more at the links below:
1) This site is my favorite and has almost EVERYTHING you need to know about Catholicism, not base on opinions, but on fact, history, tradition and the Magesterium.
2) This link gives you a quick overview of the Traditional Mass vs. the Novus Ordo mass
Again, I don't mean to open a big discussion but want to direct you to further reading. It is very valuable, not just for the sake of knowledge but for the sake of your immortal soul. If I sound dramatic, it is because it is somewhat of a dramatic subject. =)
