Since you brought up the four marks of the Christian church, I would wonder what you think of the following:
How are we "one" if there are differences of opinion on beliefs and differences in community?
Such as the differences that existed between East and West even before the year1054? Or the differences between those in the Latin Rite or the various Eastern Rites even today?
Doesn't even Rome acknowledge that, by virtue of baptism, those outside of communion with Rome are still--if their baptism is valid and licit--some sense connected to the Church Catholic?
That, I'd argue, is the starting place for that conversation.
How is the Lutheran church catholic if it cannot show an attempt to be truly universal? This does not allow one to adopt a bunker mentality.
How can the Lutheran church claim apostolic descent if there is a break in the lineage from the apostolic church?
I would first argue that there is no such thing as "the Lutheran Church". The term "Lutheran" was given by those who wanted to call us heretics. The name has stuck, and we have accepted it inasmuch as we call ourselves "Lutheran" as a helpful way of identifying ourselves within the broader sea of Christians.
But there is no such thing as a "Lutheran Church" as opposed to the one, holy, catholic, and apostolic Church of Jesus Christ.
As far as apostolic descent is concerned, in some places Apostolic Succession was retained, in other places it was not. We have argued that apostolicity is not merely by virtue of having ministers with Apostolic Succession, but in the faithful preaching and maintaining of the apostolic teaching. Wherever the apostolic word is preached, there apostolicity is maintained. Conversely, if one with otherwise valid apostolic succession does not preach the apostolic faith, they cannot claim apostolicity--a heretic cannot claim to represent the apostolic faith of the Church even if they have the "credentials" to back it up. So while Apostolic Succession is certainly a good thing when and where it safeguards the faith from heresy, false teaching, and abuses; but if it does not do that, then it is more necessary to be faithful to Christ's word and the word of His apostles than to merely claim linear descent from the apostles. To preach the word rather than merely claim the word; to believe the faith and confess the faith rather than merely claim the faith.
In this way apostolicity is maintained in the churches of the evangelical reform of the Church, whether through Apostolic Succession or without. If our confession is true, then it is true. If our faith is faithful, then let it be faithful. If we are persisting and enduring in the faithful deposit of faith given from the beginning, and if we are teaching and professing what has been believed and have Christ and His Gospel front and center--then we are Christian, we are Catholic. For the Catholic and Apostolic faith is that we confess and believe i
n one God, the Father Almighty, Maker of heaven and earth, and in Jesus Christ His only-begotten Son our Lord, et al.
I am not trying to throw rocks at the Lutheran church only. I see some of the same issues in claims by the Catholic Church centered in Rome and the Orthodox church. I hope the members here can address these common problems without making this about who is right and who is wrong.
Understood. Since we don't believe that there is a "Lutheran Church" as something distinct or other than the one Church of Jesus Christ, then that is about the sum of it. We don't see our Church as anything other than the same Church that's been from the beginning. No church was founded by Luther or any of the Evangelical Reformers. We never left the Catholic Church. The Church of 1516 is the same Church in 1517.
To believe that there is a distinct and separate "Lutheran Church" apart from the Catholic Church would mean recognizing the claims and authority which condemned Luther as a heretic--and we don't recognize that; we consider it an illicit authority.
