The LCMS response? Paraphrased, “There can be no talks until Rome admits that it is and always has been wrong on all issues, and that all Catholics are damed beyond Redemption.”
Really? I was Lutheran when the JDDJ was signed. I don’t remember this.
In fact, here’s what the LCMS actually says:
QUESTION: A non-Lutheran Christian friend of mine recently stated he believes Catholics are not saved and should not be considered Christians. What is the Synod’s belief regarding the salvation of Catholics who adhere to Roman dogma?
ANSWER: The LCMS recognizes all Trinitarian church bodies as Christian churches (in contrast to “cults,” which typically reject the doctrine of the Trinity and thus cannot be recognized as Christian).
In fact, a primary “objective” listed in the Synod’s Constitution (Article III) is to “work through its official structure toward fellowship with other Christian church bodies” — which explicitly assumes that these “other church bodies” are “Christian” in nature.
That does not lessen the Synod’s concern for the false doctrine taught and confessed by these churches, but it does highlight the Synod’s recognition that wherever the “marks of the church” (the Gospel and Sacraments) are present—even where “mixed” with error—there the Christian church is present. Such a church is a heterodox church, that is, a church that teaches false doctrine.
Of course, personal salvation is not merely a matter of external membership in or association with any church organization or denomination (including the LCMS), but comes through faith in Jesus Christ alone.
All those who confess Jesus Christ as Savior are recognized as “Christians” by the Synod—only God can look into a person’s heart and see whether that person really believes. It is possible to have true and sincere faith in Jesus Christ even while having wrong or incomplete beliefs about other doctrinal issues.
This explains why former Synod President A.L. Barry called members of the Roman Catholic Church “our fellow Christians” in his statement Toward True Reconciliation, which at the same time identifies and laments the false teachings of the Roman Catholic Church.
The great danger is that believing things contrary to God’s Word can obscure and perhaps even completely destroy belief in Jesus Christ as one’s Savior. We pray this will not happen to those who confess Jesus Christ as Savior and yet belong to heterodox church bodies, including fellow Christians in the Roman Catholic Church.

Hopefully, you’re just mistaken.
