Supported by the Lutheran World Federation and World Council of Churches, ELCA worshiping communities are encouraged to celebrate this new day, using the lectionary texts provided by the Consultation on Common Texts.  Since the seventh century, September 1 has symbolized the day of the creation of the world in the Byzantine tradition and has been the opening feast of its liturgical year (known as the Feast of the Indiction), in parallel with Rosh Hashanah marking the Jewish New Year. Creation in Christ celebrates the ongoing creation of the world in and through Christ, who sustains, unites, and holds all created things.
