Pyotr Ivanovich Konardov was born in 1870 in the village of Troitskoye, Moscow Province, into a priest's family.
After graduating from the theological seminary, he was ordained a deacon and later a priest. He served in the Church of the Ascension of the Lord on Gorokhovoye Pole in Moscow.
Shortly before his arrest, he was transferred to the Church of John the Baptist in the village of Ivanovskoye (in the Reutov District of the Moscow Region), where he served until the end of 1936.
On December 26, 1936, he was arrested following a denunciation and placed in Butyrka prison in Moscow. He was accused of "hostile attitude towards the actions of the Party and Soviet power" and sentenced to five years of exile in Kazakhstan. He served his exile at Shcherbakty station in the Kazakh SSR. There, Father Pyotr met other repressed clergy and laity. The martyrs did not abandon prayer and tried to regularly hold services as much as possible.
On November 20, 1937, he was arrested in exile as a "member of a church-sectarian counter-revolutionary group consisting mainly of clergy and sectarians of all orientations." He was involved in the group case "The Case of Archbishop Agapit (Borzakovsky) and others, Pavlodar, 1937." During interrogation, he categorically denied any involvement in sectarian groups but did not deny participating in services conducted by the Orthodox clergy in apartments.
On November 25, 1937, the NKVD Troika for the East Kazakhstan Region sentenced him to the highest measure of punishment.
He was executed on November 28, 1937, at 2 AM. His burial place is unknown.
On April 14, 1990, he was rehabilitated by the Prosecutor's Office of the Pavlodar Region for the repressions of 1937.
He was canonized among the New Martyrs and Confessors of the Russian Church at the Bishops' Council of the Russian Orthodox Church in August 2000.
