'''Anthony, John, and Eustathius'''
(Eustathios or Eustace) are 14th century [[martyrs]] (1347) of the [[Russian Orthodox Church]].
They were attached to the Muscovite mission in the court of the pagan warlord, Algirdas (Olgierd) of Lithuania. Grand Duke Algirdas was married to the Russian [[Christian]] Princess Yaroslavna, and the missionaries were present to minister to the religious needs of the princess and her retinue. The Grand Duke had nominally converted to Orthodoxy, but upon the death of Yaroslavna, he apostasised and resumed his pagan ways. All [[evangelism|evangelizing]] became strictly proscribed. The three youths, all popular and promising courtiers, were apprehended for preaching in public and brought before Algirdas, who ordered them to consume meat during a solemn [[fast]]. When they refused, he had them tortured and killed. Their incorrupt [[relics]] are now enshrined in the crypt chapel below the [[altar]] of the [[cathedral]] [[church]] in the [[Monastery]] of the Holy Spirit in Vilnius (Vilna), Lithuania.
Their [[feastday]] is celebrated on [[April 14]].
