According to Procopius, what are three contributions of Justinian?

1) Justinian I was one of the most important emperors in the history the Orthodox Church, the official church of the empire. He was described as a nursing father of the church. He put the church on a more solid footing and redefined its structure. He wanted to protect its purity and persecuted dissident Christian sects. He secured the rights of the church and the clergy and protected and expanded the monastic orders. He granted the monks the right to inherit property from private individuals and to receive annual gifts for the state and banned the confiscation of monastic property. He gave the canons of the church legal force and issued laws regarding the administration of church property, the elections, rights and obligations of the clergy, the conduct of service and episcopal jurisdiction. 2) Justinian I commissioned the Corpus Juris Civilis (Body of Civil Law) which was dubbed Justinian code in the 16th century. It came in four parts. The Codex Justinianus was a review of imperial laws going back 400 years (to the time of Hadrian). It scrapped obsolete or unnecessary laws, made changes when necessary and clarified obscure passages.
