He is known for his role in establishing the Moscow Patriarchate during his trip to Russia in 1589. Jeremias initially suggested himself as a candidature for the first Patriarch of Moscow, but Boris Godunov suggested that his residence should be Vladimir, a largely impoverished town at this time. Jeremias instead consecrated Boris's associate, Metropolitan Job, as Patriarch.
Patriarch Jeremias also obtained certain privileges for the Greek communities within the Ottoman Empire, one of which was the establishment of schools. Until Jeremias' time, there was only one Greek-language school in the Ottoman Empire, the "Great School of the Nation". With Patriarch Jeremias' influence seven schools opened in the late 16th century, in Athens, Livadia, Chios, Smyrna, Kydonies, Patmos and Yanina. Subsequently, another 40 schools opened across Greece and Asia Minor: in Skopje, Philipopolis, Andrianople, Sozopolis, Anchialos, Constantinople, Aenos, Serres, Giannitsa, Korytsa, Vlachokleisoura, Veria, Thessaloniki, Kalipolis, Kozani, Hieromerio, Tirnavo, Trikala, Paramytha, Agrafa, Arta, Karpenisi, Varnakova, Aetoliko, Thebes, Chalkida, Argos, Nafplio, Koroni, Monemvasia, Methoni, Kythera, Kerkyra, Zakynthos, Chandax (Heraklion in Crete), Rodes, Kos, Patmos, S. Lemonias and Myrtinisiotisses (Lesvos), Mykonos, Naxos. (See "Holy David and School Master Monks of Varnakova during Turkish Rule" by Holy Metropolis of Phocis, page 89.)
