The call of Christ is answered by individuals through the work of the Holy Spirit in the Word.
Not by the “unification” pronounced by self-worshipping parrots preening their vestigial Roman plumage from a perch in Saint Louis.
Your opinion is in contrast to what Jesus prayed. There is no unification in play and won't be whilst others develop doctrine outside of the Word. Kind of like those who can read John 17 and come away with a wrong opinion.
