Metropolitan Cornelius (Russian: Митрополит Корнилий, Estonian: Metropoliit Kornelius or secular name Vjatšeslav Vassiljevitš Jakobs, or Vyacheslav Vasilyevich Yakobs, Russian: Вячеслав Васильевич Якобс; 19 June 1924 – 19 April 2018)[1] was an Estonian metropolitan bishop of Tallinn and All Estonia, the head of the Estonian Orthodox Church of Moscow Patriarchate.
In 1943, he finished school and served as a psalm reader in the Church of the Nativity of the Mother of God in Tallinn.
On 27 February 1957, he was arrested by the KGB and charged with "anti-Soviet agitation" (due to his possession of religious books and conversations with believers).
In November 1960 he returned to Estonia and became rector of John the Forerunner Church in Tallinn.
On 21 August 1990, he took monastic vows in the Monastery of the Dormition at Pechery near Pskov and obtained the name of Cornelius; on 6 September 1990 he was elevated to the rank of archimandrite.
