Not UU, as they may accept others that are not trinitarian Christians, but it does reflect a level of unionism.
Well, no, of course not. I know Protestants have standards. I assume the Nicene Creed? But some even reject that. Where does one draw the line? And if one draws the line at “Jesus Christ is the Son of God” and “the Bible is God’s Word”, well, how far the lines of latitude go! There’s the OSAS crowd, there’s us Catholics, there’s the Calvinists, the Baptists, the Christians who don’t believe baptism saves us, a thousand other significant differences in the consequences of believing those two things.
Again, where does one draw the line? Why be a Lutheran, then, if it’s just as good to be Once Saved, Always Saved? I’m not saying you approve of such things, or the LCMS does. I don 't know for sure, and that’s only an example.
Our answer would be: Catholicism has baptism, but it has other sacraments and practises which flesh out the faith the vast majority of Protestants only receive in Baptism and the Bible - if that, sometimes. In other words, it is the Gospel in the fullest, and other Christians possess some of the Gospel, in varying degrees, but not all. They have the cornerstone at least, but not the whole building.
Would the LCMS say something similar?
Actually, for a Lutheran, it should be things we personally agree with, but things our communion agrees with.
…fair enough.
Although, if the LCMS began teaching something you personally didn’t agree with, what would you do? Would you stay with them because the LCMS is, as far as you know, the OHCAC?
For example, I personally am not sure Mary is such a necessary part of Christian prayer life. But I try to pray the Rosary, and I teach as the Church teaches on the issue. I would never teach contrariwise.
The bolded I disagree with because, taking that position, leaves no room for dialogue. In fact, I would contend that was the character of relationship between our communions, to a large degree, prior to Vat II.
Oh, not necessarily. You and other Protestants have pieces that we also have. I think, though, some of those pieces are out of their proper contexts. For example, the Calvinists and their relative obsession with St. Augustine, to the neglect of other Church Fathers. The goal of ecumenical dialogue, to some degree, is to get all our pieces into right context. Sort of like putting a barbecue grill together. We’d say Lutherans have thrown some pieces of the grill to the side, some other Christians perhaps up to 3/4s of the parts away. The goal is to get a functioning barbecue grill.
