Cyril V Karakallos (Greek: Κύριλλος Καράκαλλος; died 27 July 1775) was Ecumenical Patriarch of Constantinople for two periods from 1748 to 1751 and from 1752 to 1757.
A controversial figure, often blamed for his ideas about the baptism,[1] in 1755 he issued the Oros, a canonical document which, superseding the previous use of accepting Christian converts by Chrismation, stated that all non-Orthodox (including Catholic) baptisms were not valid and all converts needed to be re-baptized.[2]
