The Reformers rebelled against the post-schism Church of Rome. You stated that they accept the first three Councils, which (in order)
1. Established the Creed and rejected Arianism;
2. Clarified the creed into its present (non-philioque) form; and
3. Renounced Nestorianism and proclaimed it appropriate to refer to Mary as Θεοτόκος, or Theotokos.
I can see no reason why they would reject the subsequent 4 councils, but, oh, well. Much of the Protestantism that I grew up with was simply a rejection of anything Roman.
You do know that a group of Lutheran scholars reached out to the Patriarch of Constantinople in the late 16th century?

Sorry, my, error, Most protestants accept the first 7.
