About Agrippa Castor
Agrippa Castor was an Ancient Greek writer active around AD 135, during the reign of Emperor Hadrian. He holds a significant place in early Christian literature as the earliest recorded writer against heresy. His primary claim to recognition is the composition of a work exclusively devoted to the refutation of Basilides, a prominent Gnostic figure who died around AD 132, and his twenty-four books of 'Exegetics'.
Little is known about Agrippa Castor's life directly, with information derived from secondary ancient historical references. Both Eusebius and Jerome mention him as an author who critiqued Basilides. Eusebius references Agrippa within the context of early Gnostic successions and schools, though without further biographical detail. Jerome, in his writings, alludes to Agrippa Castor when discussing Quadratus and Aristides, and notably likens Agrippa to the first Christian 'apologists,' placing him in the company of figures like Hegesippus and Justin Martyr.
From the limited passages available, it is understood that Agrippa Castor accused Basilides of espousing teachings that diminished the moral significance of actions such as consuming food offered to idols and suggested that followers could renounce their faith during periods of persecution without serious consequence. He also noted Basilides' adherence to numerology and his use of the name 'Abrasax' for his most high God, a name found on magical gems and papyri. These criticisms highlight Agrippa Castor's role in the early theological debates and the defense of Christian orthodoxy.
