c.133 - c.190
Athenagoras was a Greek Platonist who converted to Christianity. He went to Alexandria and established a kind of Christian academy. He addressed a response to the emperor Marcus Aurelius against charges levelled at Christianity within the empire.
Aurelius had high regard for philosophy and Athenagoras used Greek rationality to make the case for Christian dogmas.
Athenagoras developed the principles to proof the existence of a single God (monotheism) a concept which made the doctrine of Trinity necessary. He suggested multiple persons in a single nature and potency.
