St Gregory Thaumaturgus
In his written oration on Origen, Gregory describes the method employed by that master to win the confidence and esteem of those he wished to convert, how he mingled a persuasive candour with outbursts of temper and theological argument put cleverly at once and unexpectedly. Persuasive skill rather than bare reasoning and evident sincerity and an ardent conviction, were the means Origen used to make converts. Gregory took up at first the study of philosophy, theology was afterwards added but his mind remained always inclined to philosophical study, so much so indeed, that in his youth he cherished strongly the hope of demonstrating that the Christian religion was the only true and good philosophy. For seven years he underwent the mental and moral discipline of Origen (231 to 238 or 239). There is no reason to believe that his studies were interrupted by the persecutions of Maximinus of Thrace, his alleged journey to Alexandria, at this time, may therefore be considered at least doubtful and probably never occurred
