The
Tridentine recension of the Roman Rite is considered to be
acceptable is changes are made (no filioque, add
an epiklesis, etc), since the Tridentine rite represents the old
Western Orthodox liturgy.
Following
the great schism in 1054 AD, the Churches of East and West began to
drift apart in both theology and praxis. Most Western Rite churches
use a liturgy which more closely resembles the Mass of Pope Pius V,
otherwise known as the Tridentine Rite. However distinctions in
vestments and rubrics, as well as commemoration of saints during the
liturgy are apparent to visitors. Additionally the use of a stronger epiclesis marks the strongest distinction
between traditional Catholic masses and the Divine Liturgy of the
Western Rites.
