Was the rite of "brother-making" exclusive to two individuals, or could a man make more than one other man his brother? Is there any part of the rite that requires you to be nonunited previously?
Adelphopoiesis, or Ordo ad Fratres Faciendum as it may have been known in the Western Church, was used to unite two men as brothers in spirit. Some sources that I have read have described this rite as a method of establishing familial bonds where they did not previously exist, for the legal purpose of extending an inheritance to a close friend for example, much like adoption, but an adoption of a sibling instead of a child.
The customs apparently differed in different areas and locations. But generally the rite existed wherever sworn kinship was practised, and may have also been practiced as a pact between soldiers or "brothers-of-arms".
Modern interpretations have tried to illustrate the rite as a union of homosexual couples, but there are cases where individuals were both heterosexually married and united to a brother. There are also many arguments that distinguish the rite from marriage, even though the ceremony has many aspects that are similar to a marriage ceremony.
My question is: Can you have more than just one brother by this rite?
