Diataxeis

Diataxeis (διατάξεις), a word anciently used for liturgies, or forms of prayer. Gregory Nazianzen calls the liturgy of St. Basil, composed by the direction of his bishop while he was presbyter of Cesarea, εὐχῶν διατάξεις, the order of prayers; and those forms and orders of divine worship collected by the author of the Apostolical Constitutions were styled διατάξεις.
