The Lukan Jump is related to the chronological proximity of the Elevation of the Cross to the Conception of the Forerunner (St. John the Baptist), celebrated on September 23. In late Antiquity, this feast marked the beginning of the ecclesiastical New Year. Thus, beginning the reading of the Lukan Gospel toward the middle of September can be understood. The reasoning is theological and is based on a vision of Salvation History: the Conception of the Forerunner constitutes the first step of the New Economy, as mentioned in the stikhera of the matins of this feast. The Evangelist Luke is the only one to mention this Conception ().
