The Holy Father, Pope Benedict celebrating the Traditional Catholic Mass, these two happen to be in the Ordinary Form:
I think I agree with Pater Ignotis on this one. The Mass when celebrated according to the mind of the Church and her promulgation of it is traditional. There are many forms of the Mass down through the ages both in the East and in the West. These are all traditional as the Mass re-presents in an unbloody way the One Sacrifice of the Mass as the bread and wine become the Body, Blood, Soul and Divinity of the crucified and risen Lord Jesus. That is the Tradition with a capital "T". The manner in which this occurs from antiquity to the present and in the East and in the West is celebrated in a variety of traditions with a little "t."
The Ordinary Form of the Mass has only minor changes in both the order and rubrics of the Mass. What has exacerbated its celebration is all the things that liturgical theologians shoved down the throats of bishops and then to priests and congregations. These innovations, such as stripping of altars and churches and even standing for Holy Communion and reception in the hand while considered traditional from the little "t" perspective should have been challenged and not allowed. But that is what happens when the river spills over during any period of reform in the Church. It happened after the Council of Trent too.
The major differences between the OF and EF Mass occur at the "prelude" in terms of the Introductory Rite, the prayers at the foot of the altar which at one time occurred in the sacristy as private prayers for the clergy (and to this day the EF Mass truly begins with the Kyrie) has been replaced in the OF with a shorter Penitential Act. The Kyrie and Gloria are still there.
The offertory rite has been simplified and is more like, from what I understand, is the offertory of the traditional Ambrosian Rite of the Latin Rite Church, thus very traditional a pre-dating the OF Mass as such.
Apart from some other minor tinkering, not much has changed except for the vernacular. If the OF Mass were celebrated Ad Orientem and in Latin with kneeling for Holy Communion, the typical lay person, even one who attends the EF Mass would not see much of a difference.
