For it is we who are the circumcision, we who serve God by his Spirit, who boast in Christ Jesus, and who put no confidence in the flesh — though I myself have reasons for such confidence ... But whatever were gains [κέρδη] to me I now consider loss for the sake of Christ. What is more, I consider everything a loss because of the surpassing worth of knowing [ὑπερέχω ὁ γνῶσις] Christ Jesus my Lord, for whose sake I have lost all things. I consider them garbage, that I may gain Christ [Χριστός κερδαίνω] and be found in him, not having a righteousness of my own that comes from the law, but that which is through faith in Christ—the righteousness that comes from God on the basis of faith. [Phil 3:7 - 9]
Clearly the heretics talked about 'gaining Christ' (Χριστός κερδαίνω) and the being was personified as a heretic.
