Sigh. I really didn't intend for that to go that way. I got annoyed when you corrected me based on a nuance, but that happened out of my own lack of humility. Sorry. Forgive me, a sinner.
With the topic of the number, as Melanchthon said - "No prudent person will struggle concerning the number or the term, if only those objects are kept which have God's command and promises." I don't really think the dispute between Constantinople and Tubingen over the number of sacraments is a "real" problem, per se, certainly not in modern terms as the nuanced Lutheran position is more or less the same as the Orthodox.
And for that reason I wish Melanchthon had been alive when the discussion between Tubingen and Constantinople had been ongoing, or able to talk to Jeremias in person or by letter. It would have been absolutely marvelous if they had been able to come to an agreement, and from what I've read of Melanchthon he was a whole lot more Orthodox than not (indeed the original letters to Constantinople were written titled "A Defense of the Orthodox Faith" with the expectation from the Lutherans that they would find complete agreement).
