People who have withdrawn from the Cause because they no longer feel that they can support its Teachings and Institutions sincerely are not Covenant-breakers—they are non-Bahá’ís and should just be treated as such. Only those who ally themselves actively with known enemies of the Faith who are Covenant-breakers, and who attack the Faith in the same spirit as these people, can be considered, themselves, to be Covenant-breakers. As you know, up to the present time, no one has been permitted to pronounce anybody a Covenant-breaker but the Guardian himself.
