When the Antiochian Western Rite Edict was issued, it became necessary to determine what additions or corrections to western liturgies would need to be made to bring those rites into conformity with the 1904 Russian Synodal decree as well as the Ukase of 1936. To that end, the Antiochian Western Rite Commission was convened in 1958 composed of Fr Paul Schneirla, Stephen Upson, Alexander Schmemann and John Meyendorff for the purpose of determining "the mode of reception of groups desiring to employ the Western Rite, and the character of the rites to be used, as well as the authorization of official liturgical texts." Meyendorff, Schmemann, and Schneirla were already familiar with the Western Rite both from having been in contact with members of the ECOF while teaching at Saint Sergius Theological Institute. Schmemann actively followed the Liturgical Movement in the Roman Catholic and Anglican Church and was an advocate for renewal of the Orthodox liturgy.
