If the three Christian churches (Catholicism, Protestantism and Orthodoxy) were broth

If the three Christian churches (Catholicism, Protestantism and Orthodoxy) were brothers, what would they do?

They were called One Holy Catholic Church not until 1000 schism. The orthodox and the protestants maybe will continue insulting their mother, the in fighting and all this sibling rivalries.

If they were brothers it would be because all of them decided to follow the New Testament only and left their own opinions and laws that man added or subtracted from the word.

We are brothers it's just that we have a dysfunctional family for the time being.
