Hi, JonNC
We certainly do agree on a lot!

Now, let me see if I can address that pesky disagreement item.
Agreed, and the Lutheran confessions agree. The question, of course, is what the definition of “authorized” is. We acknowledge that yours are. You don’t share that acknowledgement of ours. And yet, even Cardinal Ratzinger recognized the “salvation granting presence” of Christ in our Eucharist.
This is where we disagree, that only
in apostolic succession is there validity.
So, in keeping with the thread, Lutherans regard the words of Christ, “This is my Body” as Him actually changing common bread and wine into His Body, Blood, Human Soul and Divinity." There is no argument, like with some other Protestants, that Christ was using a metaphor or that the Jews misunderstood Him or ‘The flesh profits nothing…’ really means that Christ’s Flesh is worthless. The words of consecration are accepted as valid with the meaning as clearly expressed by Christ in John 6 and at the Last Supper.
Moving on… I did a bit a research (on Catholic Answers, of all places…

) and it seems like this question has come up before. After reading a number of responses, I copied the one I thought fit best. Here it is:
"For Catholics, the Real Presence in the Eucharist in which the change is described by transubstantiation can only be had if the one who presides over the celebration is a priest ordained in Apostolic Succession. In Lutheran theology, the ministry of believers acting at the Eucharist does not see any authority or power given through the Sacrament of Holy Orders.
For words of the minister to be effective, the minister must have the authority of ordination that is only found in those Bishops and Priests ordained in direct Apostolic Succession, since the authority is that of Christ himself who directly gave this authority to the Apostles and who in turn only transmitted this authority by the laying of hands in Holy Orders.
During the Reformation, the Lutheran ministry was separated from the sacramental episcopate and lost the historical succession of bishops from the apostles. Without this historical succession by laying of hands that has its authority from Christ, the Lutheran minister lacks the priestly character and the authority to preside at the Eucharist.
Without ordination that has a line that can be traced to Christ’s authority given to the Apostles, the priestly character is not given, and the Eucharist cannot be consecrated into the Body and Blood."
My understanding is this actually has it roots in Luther’s idea of the “Priesthood of all believers”. And, he specifically rejected the Catholic Prieshood.
And, here is my own personal focused opinion: for 15 centuries, ordained priests have been validly consecrating common bread and wine into the RP. Luther leaves the Catholic Church and creates several novel doctrines, possibly Sola Scriptura being his most famous, but, this priesthodd of all believers probably comes in second (?). Keeping the words is important, the issue is in changing their meaning. Since Luther rejected the CC, he very well could not go back to have his followers ordained, or have any further use for the CC as simply a practical matter. So, things were either done locally (nothing from Rome) or they were dropped.
Is there anything here that we can agree on?
God bless
