Parish Background

A small Orthodox community forms in Chicago consisting of Russians, Greeks, Serbs, and other Eastern Europeans.  Fr (St) Alexis Toth of Minneapolis occasionally conducts services for the fledgling group.

St Vladimir’s Orthodox Church, located near present-day Racine and Madison, consecrated on June 7.  First permanent priest is Fr Nicholas Grinkevich, later followed by Fr Ambrose Vretta.

Fr (St) John Kochurov of St Petersburg, Russia, becomes priest at St Vladimir’s.  The community by this time is predominately Carpatho-Russian and Russian.

Fr John Kochurov, with the blessing of Bishop (St) Tikhon, commissions architect Louis Sullivan to construct a new home for St Vladimir’s parishoners on the corner of Leavitt and Haddon.

First service in new Holy Trinity Orthodox Church is held on March 25, with Bishop Tikhon in attendance.  The Bishop consecrates the Church in August.

Bishop Tikhon and Fr John Kochurov return to Russia.

Fr John Kochurov murdered by Bolshviks in Tsarskoye Selo, Russia.  Bishop Tikhon is elevated as Patriarch of Russia.

Holy Trinity becomes the Cathedral of the new auxiliary bishop of Chicago, Theophilus.

Patriarch Tikhon dies in imprisonment in the Soviet Union.

Archbishop John (Garklavs) elected to Diocese of Chicago and Minneapolis.

Bishop Boris consecrated at Holy Trinity Cathedral to serve the Diocese of the Midwest.

Fr Sergei Garklavs becomes priest at the Cathedral.

Patriarch Tikhon is canonized a Saint in Russia.

Holy Trinity celebrates its Centennial.

His Grace, Bishop Job, is appointed as Bishop of the Diocese of the Midwest.  Also in this year, Patriarch Alexis II of Russia serves at Holy Trinity Cathedral as part of Bicentennial of Orthodoxy in America celebrations.

Fr John Kochurov is canonized a Saint in Russia.

Holy Trinity Cathedral thrives as a diverse and dedicated Orthodox community including descendants of the founders, immigrants from Eastern Europe and downstate, and converts from other faiths.
