Following the 2000 agreement a former bishop may still return to the work of a local pastor, but he or she now retains the status of bishop, even if not exercising that ministry. Worship Published in 2006, Evangelical Lutheran Worship is the main hymnal used in congregations. Some congregations, however, continue to use the older Lutheran Book of Worship published by the Inter-Lutheran Commission on Worship in 1978, and some even continue to use the older Service Book and Hymnal (SBH) of 1958 or its antecedent precedent-setting Common Service of 1888 which laid out a traditional American Lutheran liturgy and later was included in subsequent worship books and hymnals of various churches especially The Common Service Book of 1917, adopted by the old United Lutheran Church in America, a predecessor of the LCA to 1962, and The Lutheran Hymnal (TLH-1941) of the LCMS. Many congregations also make use of supplementary resources recently published as well besides those authorized for the LBW by Augsburg-Fortress, Publishers. Many ELCA congregations are classically liturgical churches. Their liturgy is rooted in the Western liturgical tradition, though recent international Lutheran-Orthodox dialog sessions have had some minimal influence on Lutheran liturgy.

On special rare occasions even a bishop's cross/crozier and mitre (bishop's headpiece) have been used to designate the ancient robes and traditions of the Church originating in Roman times of which Luther and his fellow Reformers like Philip Melanchthon considered as "adiaphora" or of permissive use. Since the Second Vatican Council of the 1960s, most major parts of the ELCA's popular liturgies are worded exactly like the English language Mass of 1970 of the Roman Catholic Church. Many ELCA congregations use informal styles of worship or a blend
