The Divine Liturgy of the Blessed Apostles (Addai and Mari)

The East Syriac anaphora of Saints Addai and Mari — possibly the oldest extant Christian eucharistic prayer. Still served by the Assyrian Church of the East and the Chaldean Catholic Church. The original form famously contains no explicit Words of Institution; the Catholic Church affirmed its sacramental validity in 2001.

3rd century (East Syriac)
