The Rite of the Holy Union is one of the Rites of the Metropolitan Community Churches all over the world as stated in Article III, Section C, paragraph 3 of the Universal Fellowship of Metropolitan Community Churches Bylaws and it says:
The RITE OF HOLY UNION is the spiritual joining of two persons in a manner fitting and proper by a duly authorized clergy, Interim Pastoral Leader (Lay Pastoral Leader) of the Church, Ministry leader or Deacon or UFMCC Elders of an affiliated MCC Church. After both persons have been counseled and apprised of their responsibilities one toward the other, this rite of conferring God’s blessing may be performed.
The essence of the Rite of Holy Union is the vow; the pledging of deepest fidelity of each other. It is the spiritual joining of two persons regardless of sexual orientation and gender identity. It is a celebration of love witness and affirmed by their friends, family, and the Church.
