Early Life and Education
Aleksandr Mikhaylovich Grenkov was born on December 5, 1812 (November 23 OS) in Bolshaya Lipovitsa, Tambov guberniya, into a family with a strong clerical tradition: his father, Mikhail Fyodorovich Grenkov, was a sexton, his mother was Marfa Nikolayevna Grenkova, and his grandfather had served as the village priest.
He was the sixth of eight children and received a strict religious upbringing. At about age twelve he entered the Tambov clerical school and advanced to the Tambov theological seminary, where he ranked among the top students. Before entering monastic life he worked as a private tutor and taught at the Lipetsk clerical school.
Monastic Life at Optina
A severe illness in 1835, shortly before he completed his studies, led him to vow that he would become a monk if he recovered. Though he recovered he delayed for several years, until a meeting with the hermit Elder Hilarion of Troekurovo, who counseled him, 'Go to Optina and you will be experienced.'
He entered Optina Monastery in Kaluga guberniya in October 1839 and was formed under two of its great elders, Starets Leonid and Starets Makary, sharing a cell with the latter. He was tonsured in 1842 and given the name Ambrose in honor of Saint Ambrose of Milan, and was ordained a hieromonk in 1845.
Under Makary he assisted in the work of translating the writings of the Church Fathers, including The Ladder of Divine Ascent by John Climacus, contributing to Optina's celebrated program of patristic publishing.
Chronic Illness
The journey to Kaluga for his ordination in 1845 brought on a grave illness that permanently compromised his health. By 1846 he had received Holy Unction, and by 1848 he required a cane to walk.
This lasting infirmity forced him into semi-reclusion for several years. Rather than ending his spiritual labor, the constraint deepened his interior life and his practice of the Jesus Prayer and hesychasm. Even when physically exhausted he continued to receive countless visitors throughout his years as elder.
Eldership and Influence
On the death of Starets Makary in September 1860, Ambrose became the principal elder of Optina, serving for roughly thirty years. He was celebrated for gifts of clairvoyance and healing, which he sought to conceal through humility.
His reputation drew visitors from across Russia, including prominent figures of the age. Leo Tolstoy visited on multiple occasions, and Fyodor Dostoevsky visited in 1878; Dostoevsky drew on Ambrose as the primary model for the Elder Zosima in The Brothers Karamazov.
In 1884 he founded the Shamordino Convent (Kazanskaya Amvrosievskaya pustyn), an inclusive community that welcomed women who were poor, sickly, or blind regardless of personal wealth — a departure from convents that required a dowry. After the death of its first abbess, Mother Sophia, he traveled to Shamordino in June 1890 to manage its affairs, where illness prevented his return to Optina.
Relics & Shrines
St. Ambrose died at the Shamordino Convent on October 10, 1891 (OS) / October 23 (NS), and his relics were initially placed in the Vvedensky (Introduction of the Theotokos) Church at Optina Monastery.
On June 24 / July 7, 1998 his relics were uncovered and transferred to the Church of the Vladimir Icon of the Mother of God at Optina, where they are venerated. He is commemorated on October 10 (OS) / October 23 (NS), the day of his repose, with a secondary feast on June 27 (OS) / July 10 (NS) marking the finding of his relics.
Veneration and Legacy
Ambrose was canonized in 1988 by the Local Council of the Russian Orthodox Church during the celebrations of the Millennium of the Baptism of Rus'; the Russian Orthodox Church Abroad added its recognition in 1990.
As the most famous of the Optina Elders, his pastoral counsel and the literary portrait drawn from him in The Brothers Karamazov gave him an enduring place in Russian religious and cultural memory.
