In that Byzantine Liturgy, (1) the Liturgy of the Word and (2) the Baptismal Liturgy with simultaneous. That is, the Baptismal Service took place in the baptistery, a separate attached building, usually round, with a pool in the middle; and simultaneously, the faithful in the Church followed the Liturgy of Seven Readings. Effectively, the whole community was kept "entertained" while waiting for the baptisms to be completed and the newly baptized to be solemnly processed in for their first experience of the Eucharistic Liturgy.

Although a brilliant book on the Byzantine service was available in German, Roman liturgists are still today largely unaware of it, and thus they reconstructed our Easter Vigil with two parts in sequence that were meant to occur simultaneously.

The spirit of Dix's genius for studying all liturgies comparatively appears to have been lost.
