A few points.
The Lutheran Church did not reject a clerical state, but it did make the nature of the clerical state a bit more loose, especially in the Germanic lands. While the Scandanavian Lutherans kept bishops, priests, and deacons in apostolic succession (and do to this day, save their error in women’s ordination), the Germanic Lutherans took a temporary out that Luther gave and made it an ecclesiastical norm. He himself said he did not wish to abolish the episcopate, and yet those Lutheran bodies that are Germanic in origin never did restore the Episcopate. Lutherans definately believe in a real and substantial presence (well, orthodox Lutherans do, anyway) in the Eucharist, but they believe that, following the example of the Incarnation, that the Christ is consubstantially present. The phrase a Lutheran seminarian I know is most fond of using is that Christ is truly and substantially present in, with, and under the forms of bread and wine. Essentially, orthodox Lutherans believe that the body and blood of Christ and the bread and the wine occupy the same space at the same time, but do not accept the concept of the annhilation of the physical composition of the bread and wine.
The Anglican Church’s chief error that resulted in more grief than it could imagine later on was the 1552 Book of Common Prayer and, more specifically, the Black Rubric. What is ironic is that as late as 1570, Rome was still making reunion overtures to the Anglican Church - including an offer to allow them to use the BCP as long as the Black Rubric was struck. While the BR was softened in 1662 and by 1850 was generally ignored by Tractarians, it did not stop the condemnation of Anglican Orders in 1896. That beign said, the justification for said condemnation is pretty weak, citing a fable concerning early Anglican ordinations and essentially invalidating ordinations conducted in the Iberian Peninsula (which used a form almost identical to Cranmner’s Ordinal). Either way, since Apostolicae Curae, the Anglican Church has kept slipping and slipping - first contraception, then women’s ordination to the priesthood, and now, well… we all know where things are headed now.
Both the Lutherans and Anglicans, with some nudging and some cleaning of house, could be reunited with the Catholic Church without too much difficulty.
It’s the Reformed folks that really botched up things beyond any illusion of simplicity in restoration. With views on the Eucharist that are downright nuts, double predestination, and (at one point) the constant preaching of law, law, law, law as opposed to law and gospel… to utter abandonment of anything resembling a clerical structure that could be called apostolic, and the outright rejection of all tradition (save that invented after 1530).
Just some random thoughts.
