# Latinisation of liturgy

Latinisation of liturgy refers to the process by which non-Latin Christian traditions, particularly those of Eastern Churches, adopted elements of the Latin Church's liturgical practices, theology, and customs. This phenomenon was often driven by ecclesiastical or political pressures and has left a lasting impact on global Christianity, sparking both unity and controversy. While it facilitated closer ties with the Roman Catholic Church, it also led to the suppression of local liturgical traditions and significant debates over ecclesial identity.

## Background

The origins of Latinisation trace back to the early consolidation of the Latin Church's influence in Western Europe during the Early Middle Ages. As Christianity spread, the Roman Rite became synonymous with Catholic identity. Non-Latin Christian communities, such as the Goths and Celts, encountered pressures to align their liturgical practices with those of the dominant Latin Church.
During the Crusades (11th–13th centuries), encounters between Western and Eastern Christians introduced Latin customs to the Eastern liturgical sphere. Following the Union of Florence (1439) and the establishment of Eastern Catholic Churches in the wake of the Protestant Reformation, Latinisation intensified as Eastern Churches came into communion with Rome. These Churches were permitted to retain their liturgical traditions but were often compelled or encouraged to adopt Latin practices to emphasize their allegiance to the papacy.

## Notable Latinisations
### Synod of Diamper

The Portuguese colonial authorities and Jesuit missionaries convened the Synod of Diamper to bring the Saint Thomas Christians of India into the Latin Padroado system. The synod prohibited East Syriac practices, replacing them with Latin customs, including changes in liturgical texts, vestments, and hierarchical structures. These actions eventually led to the Coonan Cross Oath in 1653, which split the community into factions.

### Maronite Church

The Maronite Church underwent a gradual Latinisation process following its communion with Rome in the 12th century. Western liturgical elements, such as the prohibition of infant communion and the introduction of Latin sacramentals, were integrated into its West Syriac liturgy. By the 19th century, the Maronite liturgy was considered highly Latinised, prompting modern reforms to restore its ancient traditions.

### Ruthenian Uniate Church

The Synod of Zamość authorized the addition of Latin elements to the Byzantine Rite, including the insertion of the Filioque clause into the Nicene Creed and commemorations of the pope in the Ektene. These changes aimed to solidify unity with Rome but were criticized by Orthodox counterparts and some Catholic theologians for diluting the Byzantine tradition.

### Chaldean Catholic Church

The adaptation of the Anaphora of Addai and Mari to include an explicit consecration narrative is another example of Latinisation. The unmodified version of this East Syriac liturgy lacks the Words of Institution traditionally required for Eucharistic consecration in the Latin Church. This modification was criticized for altering an ancient rite but later approved for ecumenical use by the Vatican in 2001.

## Debates and controversies

Latinisation has been a source of significant theological and cultural debates. Critics argue that it marginalized local liturgical practices and created divisions within Christian communities. For example, the Coonan Cross Oath of 1653, a direct response to Latinisation, led to a schism among the Saint Thomas Christians, resulting in the formation of independent and Orthodox-aligned churches.
Theological concerns have also been raised about the imposition of Latin elements on Eastern liturgies. Many Eastern Christians viewed these practices as foreign and intrusive, disrupting the organic development of their traditions. Some Catholic theologians have criticized Latinisation for undermining the principles of inculturation and ecclesial diversity.

## Modern perspectives

The Second Vatican Council marked a turning point in addressing the legacy of Latinisation. The decree Orientalium Ecclesiarum emphasized the importance of preserving the authentic traditions of Eastern Catholic Churches. It called for a return to their ancient liturgical, theological, and spiritual practices while discouraging further adoption of Latin customs.
Efforts to reverse Latinisation have been uneven across Eastern Catholic Churches. For example, the Syro-Malabar Church has made strides in restoring its East Syriac heritage, though internal resistance persists. The Maronite Church has similarly undertaken reforms to recover its Syriac roots while retaining some Latin influences.

## Cultural impact

Latinisation has had a profound impact on the cultural and artistic expressions of Christian communities. Western influences, such as Renaissance-style iconography, Baroque church architecture, and polyphonic choral music, became prominent in many Eastern Churches. These adaptations were often seen as a mark of Roman Catholic identity but have sparked debates about their appropriateness within Eastern liturgical contexts.
The adoption of Western practices, such as pews and altar arrangements, has also been controversial. Some Eastern Orthodox and Oriental Orthodox communities that incorporated Latin-inspired elements later abandoned them in favor of their traditional practices, reflecting a broader trend of reclaiming authentic heritage.
