Religion and the Church

The conquest of the Bulgarian state and the destruction of the Bulgarian Patriarchate had a profoundly negative impact on the religious life of the Bulgarian people. The loss of native ecclesiastical protection and the gradual infiltration of Byzantine clergy particularly affected monasteries, which had been centers of both financial support and cultural mission. The eastern parts of the kingdom suffered first from these hardships, marking a decline in the autonomy and vitality of Bulgarian religious institutions.

Throughout the 14th century, Bulgaria experienced significant spiritual activity, closely connected to broader Orthodox developments such as hesychasm. Bulgarian rulers, especially Ivan Alexander, actively engaged with hesychastic teachings, establishing ties with prominent figures like Gregory of Sinai, who had spent considerable time within Bulgarian territory. This spiritual engagement was part of a larger religious policy that also included protecting monasteries and combating heresies.

Heresies, particularly dualist ones such as the Bogomil and earlier Paulician movements, posed a serious challenge to the Bulgarian Church and society. These heresies rejected key orthodox doctrines, criticized the institutional church, and promoted ascetic and anti-materialist lifestyles. The Bogomils, organized into communities with elders and teachers, rejected the Bible as influenced by the devil, denied the sanctity of churches and sacraments, and opposed the clergy's mediating role. Their presence and spread, especially after the weakening of state borders, alarmed ecclesiastical authorities and prompted active opposition.

The Church's struggle against heresy intensified in the second half of the 14th century, marked by church councils convened in the capital in 1350 and 1360, which condemned groups like the Bogomils, Varlaamites, Adamites, and Jews. Patriarch Evtimiy of Tarnovo emerged as a tireless anti-heretical fighter, rigorously punishing heretics and those deviating from true Christian faith, while also combating remnants of pagan beliefs preserved among the Bulgarian people. His efforts were both spiritual and practical, aiming to strengthen the faith as a weapon against external enemies, particularly the advancing Turks.

The external threat of the Turks was a dominant concern in religious and political discourse. Hymnographers like Ephrem composed prayers and canons invoking divine protection for the king, the capital city (likely Tarnovo), and the people, seeking a peace that would bring salvation rather than mere temporary truce. Ephrem's works distinguish between the king's enemies, identified as the Turks, and the internal enemies of the Church, the heretics, reflecting the dual challenges facing Bulgaria.

Socially, medieval Bulgarian society was structured into three main estates: the clergy (oratores), the nobility and warriors (bellatores), and the common people (laboratores). This tripartite division was reflected in literature and ecclesiastical texts, underscoring the interconnectedness of church, state, and society. The clergy included patriarchs, metropolitans, bishops, priests, and monks, with monastic reform and moral correction being pressing concerns due to widespread laxity and violations of monastic rules.

Despite the challenges, Bulgarian religious culture flourished with the production of liturgical, canonical, and theological works, as well as hagiographies and hymnography. However, the daily life of Bulgarian society, especially its struggles with pagan remnants, moral decay, and heresies, was less frequently depicted. The efforts of church figures like Evtimiy and Ephrem provide valuable insights into the spiritual and social realities of the time, highlighting the Church's central role in preserving identity and faith amid political decline and external threats.
