Most of the Orthodox delegates wanted to just get the reunion over with as quickly as possible, so that they could secure help for their people. However, one Orthodox Bishop - Mark of Ephesus, wanted a real theological dialogue to take place. He believed that there were serious theological controversies that had to be discussed, and he was appalled that his fellow Orthodox bishops put political expedience over issues of faith. After the Council was over, and reunion was officially proclaimed, the Orthodox bishops returned home. Upon his return Mark of Ephesus wrote vehemently against the Council, calling it a “false union,” and he stirred up public opinion against it. However, the Orthodox leadership remained in full communion with Rome right up until Constantinople fell (the promised military aid from the West never materialized). When the Muslims took over the city, they appointed Orthodox bishops who were opposed to the union, and it was officially dissolved.
