Fixed it.
It is probably wise to offer a precise definition of “Open Communion” since that term can mean the extreme of offering our Lord’s Body and Blood to any and all who present themselves—even pagans and other non-Christians (as is practiced in some Episcopal congregations)—or the more restictive practice of most ELCA congregations of inviting “all Baptized persons who believe in the Real Presence of Christ for the forgiveness of their sins...”
It is argueable that the ELCA has departed from the Galesburg Rule by opening Lutheran Altars to non-Lutheran communicants. It is equally argueable that the LCMS has departed from the Galesburg Rule by not opening their Lutheran Altars to all Lutherans communicants. The practice is more restrictive than Rome (which communes all who are in communion with the Bishop of Rome, regardless of Rite) and Orthodoxy (which communes all who are Chrismated, regardless of ethnicity).
In the LCMS's view, the Bible does not contain errors. The creation story is told as fact, rather than as an analogy. If we start with the Bible as inerrant, then what else can we believe than that God created the world in 6 days and rested on the 7th?
The LCMS accepts the possibility that the world may have been created mature. I believe the term "Young Earth" is a misnomer. A better term would be "Recent Creation".
Furthermore, Adam's sin not only changed man, but all of creation. The rules after sin entered the picture may not be consistent with the rules before sin entered the world.
