I strongly agree with the bolded. Particularly for Lutherans (at least well-catechized Lutherans), simply hopping to another communion is difficult. We have little in common with many to most other protestant communions regarding, centrally, the sacraments.First, I am just a regular church go-er, trying to educate myself, and continue to “faith build”. I do not have an advanced degree, nor have I been able to devote a lot of time to theological study, though I do look forward to one day. That said, I can (as of now) just give answers on what I have seen and experienced first hand.
**It is not quite that easy or common to just float between denominations. The theology between various denominations is not so similar that our churches are interchangeable; **that is offensive to say, though I’m not sure it was meant to be. I hope it was not. That said, you are correct that it would not be seen as changing religions. Someone who would leave the Methodist church to become Presbyterian (or vice versa) would still be Christian. That is the most important thing.
This Lutheran, however, would be more likely to become Catholic or Orthodox than any other kind of protestant, with the possible exception of Anglo-Catholic.
