- Agaton — A Romanian masculine baptismal name of Greek origin, historically borne by several Christian saints, hierarchs, and monks, including Pope Agatho in the 7th century. Within hagiographical and cultural contexts, the name evokes the concept of spiritual goodness, gentleness, and moral purity, frequently utilized within Orthodox monastic environments as a monastic name.
- Achillius — A hagiographic, archaic, or popular Romanian variant of the name Achilles, historically used primarily in the Orthodox calendar and church texts to designate Saint Achillius, the 4th-century bishop of Larissa. This name circulated in the medieval rural environment as a rare masculine given name, borne by individuals dedicated to the protection of this saint renowned for his miracles and participation in the First Ecumenical Council.
- Antipascha — A theological and liturgical name for the first Sunday after the Resurrection of Christ, also known in Eastern Christian tradition as Thomas Sunday. This structural feast does not signify an opposition to Holy Easter, but translates from Greek as 'instead of Easter' or 'the renewal of Easter', marking the closing of the Easter octave and the renewal of the Resurrection celebration through the confession of Apostle Thomas.
- Astion — The name of a 3rd-century Christian martyr saint who suffered and was decapitated in the fortress of Halmyris (today in Dobrogea, Romania) alongside the priest Epictetus, being considered the oldest documented martyrs on Romanian territory. In an onomastic sense, it represents a rare male given name of Greek origin, celebrated in the Orthodox calendar on July 8th.
- Astrenie — A rare onomastic or hagiographical variant, historically used in Romanian church manuscripts as a local adaptation for the feminine proper name Asteria or to denote an abstract regional form linked to stellar-astral influence in popular beliefs. In a religious context, it can refer to Saint Asteria (Astrenie), a virgin and martyr from the early Christian centuries, commemorated in synaxaria.
