The Maronite liturgy is older than that of the Latin Church. Following the Ascension of our Lord, the Apostles set out to bring the good news to the world. St. Peter went to Antioch where he served as bishop. The Antiochene-Syriac Maronite liturgy dates back to that time. Of all the Catholic Churches, the Maronite Church retains the jewish heritage more than the others, as evidenced by the use of Syriac Aramaic, the everyday language of Jesus, in its liturgy.
A Roman rite Catholic may attend any Eastern Catholic Liturgy and fulfill his or her obligations at any Eastern Catholic Parish. A Roman rite Catholic may join any Eastern Catholic Parish and receive any sacrament from an Eastern Catholic priest, since all belong to the Catholic Church as a whole. I am a Roman Catholic practicing my faith at a Maronite Catholic Church. Like the Chaldeans, the Maronites retain Aramaic for the Consecration. It is as close as one comes to being at the Last Supper.

There was a Marionite Church in San Antonio. We always wanted to attend Mass there, but somehow never did.
