Mainstream denominations have been less inclined to allow lay people to preside over the sacrament, preferring to use ordained ministers or priests for this role.
In some cases, individuals who have received a pastoral call are authorized to celebrate the Lord's Supper prior to their eventual ordination, although this practice is not in accord with the denomination's own worship statement, The Use of the Means of Grace.
Lay presidency of any kind would seem to be in conflict with Called to Common Mission, the full communion agreement between the ELCA and the Episcopal Church, which prohibits the practice.
Theological opinions around the appropriateness of lay presidency are not uncommon in the ELCA, which is a merger of traditions that include both quasi-sacramental and purely functional understandings of ordained ministry.
Lay presidency would also seem to contradict Article 14 of the Augsburg Confession, which states that "no one should publicly teach in the Church or administer the Sacraments unless [he/she] be regularly called."
