IOW - United, we stand; divided, we fall.
Unity among Catholics, Eastern Orthodox, Oriental Orthodox, Anglo-Catholics and certain groups of Lutherans may have enough in common to possibly unite with the Holy Spirit’s aid, but I don’t know if unity with those who who reject apostolic succession is possible.
>> “IOW - United, we stand; divided, we fall.” <<
According to our Lord, its the opposite of that:
Matthew 10:
34] Think not that I am come to send peace on earth: I came not to send peace, but a sword.
[35] For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law.
[36] And a man’s foes shall be they of his own household.
[37] He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me.
[38] And he that taketh not his cross, and followeth after me, is not worthy of me.
[39] He that findeth his life shall lose it: and he that loseth his life for my sake shall find it.
[40] He that receiveth you receiveth me, and he that receiveth me receiveth him that sent me.
