The valid Orthodox bishops keep things okay, the invalid Anglican and Lutheran do not.
I came from the Lutheran church to Catholicism and then Traditional Catholicism. I was born just after the "Green Hymnal" (Lutheran Book of Worship) came out. Lutherans take forever to change things, and started writing the order of worship in that hymnal shortly after Vatican II in an effort to bring themselves into closer union with Rome, possibly even looking to reunion.
It was based in large part on Luther's original "German Order of Mass" which was a shortened, clarified version of the hodge-podge that some pre-council-of-Trent masses were. Remember that prior to the council of Trent, you could find as many abuses in some Medieval masses as you could in a Novus Ordo mass today, they were just different abuses. These abuses of the mass were things that led directly to the illicit selling of indulgences and extortion of money by the church which Luther's 95 theses were concerned with.
To make a long story short, the two churches passed each other. The Lutheran church became liturgically rigid and quite orthodox among its more educated members, while the Novus Ordo church moved into the more liberal, feel-good, man-centered mass we all know and love
. This condition persisted until the early- to mid-nineties, when the Lutheran church released the "with one voice" liturgy and once again began allowing the exclusion of the more "catholic" elements of the Lutheran service (Litanies instead of the Kyrie, Angus Dei, and Sanctus, adding some sort of "sign of peace," and other things that were similar to the NO mass, but still different.) This is what drove me out of the Lutheran church and into atheism.
Lutherans (for the most part) want to rejoin the Catholic church (outside the Missouri Synod, they leave the word "catholic" in the Apostles' and Nicene Creeds), but want to know that they're going to be protected from the abuses that Luther was so worried about. A well-educated Lutheran will admit to believing in:
- A purgative process (maybe the actual place of purgatory, maybe simply a process God puts imperfect souls through before joining perfect union with Him in heaven, but fully under God's control, not in any way subject to the will of the Church Militant, except through prayer to Him.)
- The primacy of the Pope among Bishops (more than most of the schismatic Orthodox admit to.)
- The miracle of the transubstantiation (if you describe it, but if you call it "the miracle of transubstantiation, the Lutheran might stick, but if you say "do you believe that the bread and wine truly are the body and blood of Christ during the Eucharist" a well-educated Lutheran will answer yes.)
- That the BVM is worthy of veneration (the rosary is coming back into vogue among more conservative Lutherans. This is largely a result of John Paul the Beloved's push to bring people back to the rosary.)
- That the Saints are worthy of veneration (again to the Creeds "the Communion of the Saints")
I'm sure there are others, but I have to run to a meeting. I'll simply conclude by saying that a Traditional Catholic and a Lutheran who fell in love with the "Green Hymnal" liturgy will have a lot more in common, religiously, than a Traditional Catholic and a Catholic who is devoted to the Novus Ordo mass.
