Synodal Letter to the Bishops of Africa

This synodal letter was issued late in Athanasius's career, between 368 and 372, written in Greek in the name of a synod of Egyptian and Libyan bishops gathered around him and addressed to the bishops of the African provinces. It responds to a specific agitation: parties sympathetic to Homoian or Arian positions were pressing African bishops to treat the Nicene Creed as still open to debate and to convene a fresh council that might revisit or soften its terms, above all the word homoousios. Athanasius writes to stop this proposal before it gains ground.

The letter's argument is structural rather than merely polemical. Athanasius insists that the very call for a new synod to reconsider Nicaea is itself the danger, since it concedes that a matter settled by the whole Church under the guidance of the Holy Spirit remains uncertain. He rehearses the history of the Council of Nicaea in 325, defends the precision of homoousios against charges of ambiguity or innovation, and argues that the bishops who framed it did so with full deliberation, not under duress or confusion. Running beneath the specific vocabulary dispute is a claim about conciliar authority itself: a council that has rightly confessed the apostolic faith does not require periodic re-litigation, and the demand for endless reconsideration is a tactic for destabilizing the truth rather than a genuine search for it.

This letter belongs to a small cluster of synodal writings from Athanasius's final years, alongside the Tomus ad Antiochenos and his letter to Jovian, in which he works to consolidate the Nicene settlement after decades of imperial pressure and shifting creeds. It shows him acting less as a combatant defining new terms and more as an elder statesman securing what had already been won, and it became an important witness for how the ancient Church began to think about ecumenical councils as closed and authoritative rather than perpetually revisable. Later writers on conciliar theology and the reception of Nicaea drew on precisely this claim.

Who should read this: students of the fourth-century Trinitarian controversy and of the early development of conciliar authority will find it a compact, sharply argued primary source. It is not devotional reading and assumes familiarity with the Arian controversy and the Nicene Creed; readers wanting an introduction to Athanasius's theology should start elsewhere, such as On the Incarnation, before coming to this late and highly occasional piece.
