You see, the LCMS sees itself as being what Roman Catholicism out to be

.
I think that the papacy is precisely part of the problem. The fact that the Jesuit order has been able to preach liberal Christianity for at least 100 years now with the agreement of different popes sent the signal that it is OK to preach deviant forms of Christianity as long as it is done while acknowledging the pope as nominal “Supreme Leader”.
The LCMS has been a staunch defender of true Christianity while the popes were cozy with Notre Dame or Jesuit types. Take the Notre Dame invite of pro abortion, pro gay marriage president Barack Obama. The attitude of the Vatican, was one agreement. And the new pope is even more cozy with American liberalism than previous popes. No way Obama will ever deliver a commencement speech at any of the colleges of the Concordia system.
So, I think we should thank God for the LCMS, and other protestant traditions, that still teach true Christianity.
The Catholic Church is holy; that holiness is not affected by the holiness of Catholics in a given time or place (though that
is important to those individuals). Likewise, the Catholic Church preaches the Truth. The truthfulness of Catholic doctrine is not affected by how many Catholics happen to agree with it at a given time. No college is the Catholic Church, and Catholicism is not cozy with liberalism or conservatism.
The LCMS, to its credit, affirms Christianity. As it should, as it is
bolstered by
Scripture, The Creeds,
The Ancient Church Councils, The Early Church Fathers, The Foundational *Documents of Lutheranism, and The Prayerful Guidance of Godly *
Leaders and Pastors. No danger of them going astray!
So you can see with such a powerful safety net the LCMS is in a
much safer situation from other Lutheran groups that have drifted away from historic Christianity, and become subordinate to the secular culture. Those other Lutheran groups were, sadly, limited to the guidance of only scripture, the creeds, the ancient church councils, the foundational documents of lutheranism, and prayerful guidance of godly leaders and pastors. The ELCA, etc, did the best they could with what little they had; but obviously it just isn’t enough.

I sincerely honor the LCMS and WELS and agree they maintain much fidelity. I want to know more about their strengths. But what is the standard or template for “fidelity”? To a large extent, it was, and continues, to be, Catholicism. You are correct to applaud LCMS as mostly right; now take a closer look at the template - their template - for “rightness”.
