Abstract
The intention here is to propose a new critical edition of the so-called Epistula synodalis a text traditionally attributed to Amphilochius of Iconium, but which the Author considers to be spurious. Alongside the Italian translation of the letter, based on a comparative commentary with the writings of Basil, a strong dependence of this text on Cappadocian Fathers’ Trinitarian theology and pneumatology is brought to light. However, its origin is probably an anonymous work, only subsequently associated with Amphilochius.
