Filioque clause

Theological meaning

At stake in the dispute is the language used to describe the relations among the three persons of the Trinity. Supporters of the Filioque say the Holy Spirit proceeds from the Father and from the Son as from a single principle, which they argue safeguards a close relation between Son and Spirit. Opponents contend that the original creed, as formulated by the early ecumenical councils, names the Father alone as the principal source of the Spirit’s procession and that adding Filioque alters the balance of Trinitarian wording and raises theological problems about origin and monarchy within the Trinity.

Historical development

The Filioque originated in the Latin-speaking churches of the West during the early Middle Ages and gradually became part of the Creed in many Western liturgical traditions. Its adoption was uneven and occurred in different regions at different times. The insertion of Filioque into the Creed used in the West contributed to growing tensions between Western and Eastern Christians and is commonly cited among the causes associated with the Great Schism between Rome and Constantinople in the eleventh century. Over subsequent centuries the phrase was defended by Western theologians and criticized by Eastern theologians, each appealing to different theological emphases and ecclesial practices.

Uses, examples and contemporary status

Today the Filioque appears in many versions of the Creed recited in Western churches. The Protestant traditions that follow Western liturgy typically retain it, as do many in the Anglican Communion. Some Eastern Catholic churches, which are in communion with Rome, continue to use the original form of the Creed without the Filioque in their languages and rites while accepting Roman theological formulations. Modern ecumenical dialogues have tried to clarify the underlying theology and to seek language that respects both traditions; these discussions have reduced polemical rhetoric though they have not produced a universal change of practice.

Key distinctions and notable points

• Textual difference: The single phrase "and from the Son" distinguishes the Western and Eastern liturgical texts.
• Theological emphasis: Western theology has tended to stress relational formulations that include the Son in the Spirit’s procession; Eastern theology has emphasized the Father as the unique source or "monarchy" of the Godhead.
• Ecumenical impact: Filioque is both a doctrinal question and a question about authority and how changes are made to ecumenical creeds.
• Ongoing dialogue: Churches continue to discuss historical context and theological language to find mutual understanding.
